2. Basis of Contract

2.1 Formation

These Terms and Conditions constitute the entire basis upon which Astell provides Services. They supersede all prior representations, negotiations, and agreements whether oral or written. No variation to these Terms shall be effective unless agreed in writing and signed by an authorised representative of Astell.

2.2 Order Acceptance

A contract for Services is formed when Astell issues a written confirmation of an order, or when an Astell engineer commences work at the Customer's site, whichever is earlier. Quotations issued by Astell are valid for 30 days from the date of issue unless otherwise stated.

2.3 Precedence

In the event of any conflict between a Service Contract and these Terms, the terms of the Service Contract shall prevail. These Terms shall otherwise prevail over any terms or conditions issued by the Customer.

2.4 Third-Party Equipment

Astell may provide Services on Equipment of other manufacturers at its discretion. In such cases, Astell's liability is limited to the work actually carried out and does not extend to any pre-existing condition, defect or original design of the third-party equipment.

3. Scope of Services

Astell provides the following Services to customers in the United Kingdom and internationally:

UKAS Single-Point Calibration

Verification that the autoclave chamber reaches and maintains the required sterilisation temperature for the agreed hold time. Carried out under Astell's UKAS accredited laboratory scope.

UKAS Multi-Point Calibration (Validation)

Full temperature mapping of the autoclave chamber using calibrated thermocouple probes. See Section 5 for full details.

Non-UKAS Calibration Check

Informal calibration verification outside UKAS accreditation scope, provided at the Customer's request. Results are advisory and do not carry UKAS accreditation status.

Planned Preventative Maintenance (PPM)

Scheduled servicing to maintain equipment reliability, safety and compliance. Frequency defined in the Service Contract or quotation. See Section 6.

Breakdown Response

Reactive attendance to Equipment faults for both service contract and non-contract customers, subject to availability and applicable charges.

Spare Parts Supply

Supply of genuine Astell spare parts and approved components for UK and international distribution. See Section 9.

Technical Support

Remote and on-site technical assistance, operational guidance and troubleshooting for UK and international customers.

4. Single-Point UKAS Calibration

4.1 Purpose and Process

Single-point UKAS calibration confirms that a sterilisation cycle achieves the agreed sterilisation temperature and maintains that temperature for the agreed hold time. This service verifies that the load reaches temperature and that the cycle is performing as specified.

4.2 Certificate Issuance

Upon successful completion of single-point calibration, Astell will issue a UKAS Calibration Certificate under its accredited laboratory scope. Certificates will be provided electronically as standard. Hard copy certificates may be requested and will be supplied by post or handed to site personnel on the day of the visit.

4.3 Scope Limitations

Single-point calibration confirms temperature performance at the specified setpoint and hold duration. It does not confirm temperature uniformity or distribution throughout the chamber. Where full chamber temperature mapping is required, customers should request multi-point calibration (Validation) as described in Section 5.

4.4 Non-UKAS Calibration Checks

Where a customer requests a non-UKAS calibration check, Astell will carry out the relevant measurements and provide an advisory report. This activity falls outside Astell's UKAS accreditation scope. Non-UKAS calibration check results do not constitute UKAS accredited certification and should not be used for regulatory or compliance purposes requiring UKAS accreditation.

4.5 Pressure Checks — Important Notice Regarding Accreditation Scope

Pressure Checking — Accreditation Limitation

Astell is not UKAS accredited to check or verify pressure against a traceable measurement standard. Any pressure checks carried out by Astell engineers during service or maintenance visits are performed solely as a practical operational aid — for example, to assist with fault diagnosis, to confirm that the autoclave is functioning within expected operating parameters, or to support the completion of a service task.

Such pressure checks do not constitute accredited calibration of pressure, do not produce a UKAS certificate for pressure, and must not be used or represented as a formal pressure calibration result for regulatory, compliance, or quality management system purposes. Customers requiring accredited pressure calibration against a traceable standard must arrange this through a suitably UKAS-accredited third-party provider.

5. Multi-Point Calibration (Validation)

5.1 Purpose

Multi-point calibration, commonly referred to as Validation, provides comprehensive temperature mapping of the entire autoclave chamber. Its purpose is to confirm that the entirety of the chamber achieves and maintains the required sterilisation temperature throughout a full sterilisation cycle, thereby confirming that every part of the load receives an effective sterilisation treatment.

5.2 Process

The validation process comprises the following activities:

• Placement of calibrated thermocouple probes at multiple points throughout the autoclave chamber to monitor temperature distribution across the full chamber volume.
• Where a load sense probe is fitted to the unit, this will be used in conjunction with the thermocouple array to provide representative load temperature data.
• The autoclave is run through a complete sterilisation cycle whilst all probe data is continuously recorded.
• Temperature distribution data is analysed to confirm that the entire chamber achieves the required sterilisation temperature for the required duration.
• Where the temperature distribution data indicates that calibration adjustments are required, Astell's engineer will make the necessary calibration adjustments to the Equipment so that the entirety of the chamber reaches and maintains the correct temperature value, thus ensuring a fully and completely sterilised load.
• Where adjustments are made, the cycle will be re-run as necessary to confirm the adjusted performance.

5.3 Validation Report and Certificate

Upon successful completion of the validation process, Astell will produce and issue the following documentation:

• Validation Certificate: A UKAS accredited certificate confirming that the Equipment has been validated to the agreed parameters. The Validation Certificate is valid for a period of twelve (12) months from the date on which validation was first performed on the autoclave, unless a shorter validity period is specified in the relevant contract or protocol.
• Validation Report: A detailed technical report presenting all recorded temperature data from the validation exercise. The report includes graphical representations and charts of temperature performance across the chamber throughout each stage of the sterilisation cycle, providing a complete and transparent record of the Equipment's thermal performance.

Hard copies of the Validation Certificate and Validation Report may be requested and will be supplied by post or handed to site personnel on the day of the visit. Electronic copies are provided as standard.

5.4 Re-Validation

Re-validation will be required in any of the following circumstances:

• Upon expiry of the twelve-month validation period.
• Where any significant modification has been made to the Equipment or its sterilisation cycle parameters.
• Where there has been a material change to the load type or load configuration.
• Where Equipment has been relocated or reinstalled.
• Where a fault or repair has been carried out that may have affected calibration or temperature performance.
• Where the Customer's quality management system, regulatory body or contractual obligations require re-validation.

Where customers are uncertain whether a change requires re-validation, they are encouraged to contact Astell's service team for guidance.

5.5 Customer Protocols

Where the Customer has specific validation protocols, qualification requirements (IQ/OQ/PQ) or site-specific documentation requirements, the Customer must communicate these to Astell in writing prior to the validation visit. Astell will endeavour to accommodate such requirements; however, additional charges may apply where non-standard protocols or documentation significantly extend the scope of the service.

6. Planned Preventative Maintenance (PPM)

6.1 Purpose

Planned Preventative Maintenance is designed to maintain Equipment reliability, maximise operational uptime, safeguard the Equipment's lifespan, and ensure continued safe operation in accordance with applicable regulations and the manufacturer's specifications.

6.2 Activities

PPM activities will be defined in the relevant Service Contract or quotation. They may include, but are not limited to, the following:

• Full functional test of the autoclave, including all cycle types fitted.
• Visual and physical inspection of mechanical and electrical components.
• Inspection and testing of all safety devices, including pressure relief valves, door interlocks, over-temperature cut-outs and other protective devices.
• Inspection and replacement of service items including door seals, filters, gaskets and consumables as required.
• Inspection of steam generator, water quality, and associated pipework where applicable.
• Calibration verification (single-point, non-UKAS temperature) unless UKAS calibration is separately specified.
• Operational pressure checks to assist with the service task (see Clause 4.5 regarding the accreditation scope of pressure checks).
• Review of fault logs and cycle data where accessible.
• Completion and issuance of a Service Report.

Regular servicing and timely replacement of service parts is strongly recommended to protect the life expectancy of the Equipment.

6.3 Service Report

Upon completion of each PPM visit, Astell will issue a Service Report documenting the work carried out, the condition of the Equipment, any parts replaced, and any recommendations for further action. The Customer will be asked to sign the Service Report to confirm completion of the visit.

6.4 Frequency

PPM frequency will be specified in the Service Contract. Where no service contract is in place, PPM frequency will be agreed at the time of booking. Astell recommends annual PPM as a minimum for most laboratory autoclave applications, subject to Equipment type, usage frequency and applicable regulatory requirements.

7. Service Contracts

7.1 Contract Benefits

Customers holding a Service Contract with Astell will benefit from scheduled and prioritised service provision. Contract terms will be specified in the individual service agreement and may include:

• Agreed number of PPM visits per annum.
• Priority response to breakdown calls ahead of non-contract customers.
• Agreed response time targets for breakdown attendance.
• Discounted rates for labour and/or spare parts.
• Calibration or validation services included or offered at preferential rates.
• Technical support access.

7.2 Contract Duration and Renewal

Service Contracts are typically offered on an annual basis and will automatically lapse at the end of the contract term unless renewed. Astell will endeavour to contact the Customer in advance of contract expiry. Astell reserves the right to review contract pricing at renewal.

7.3 Contract Suspension

Astell reserves the right to suspend or terminate a Service Contract in the event that:

• Payment obligations are not met in accordance with Clause 12.
• The Customer fails to provide safe access or suitable conditions for service attendance.

8. Breakdown Response and Non-Contract Service Calls

8.1 Service Contract Customers

Contract customers will receive priority breakdown response subject to the terms of their Service Contract. Astell will use reasonable endeavours to meet agreed response times but accepts no liability for delays caused by circumstances outside its reasonable control, including Force Majeure Events, parts availability, or access issues.

8.2 Non-Contract Customers

Non-contract customers may request breakdown attendance on a chargeable basis, subject to engineer availability. Response times for non-contract customers are not guaranteed. Charges may include:

• Engineer call-out fee.
• Travel time and mileage at rates applicable at the time of visit.
• Labour charges at Astell's standard or applicable rate.
• Spare parts at list price plus applicable handling charges.
• Accommodation where an overnight stay is reasonably required.

8.3 No-Fault Visits

If an engineer attends site following a reported breakdown and no fault is found with the Equipment (including where the fault cannot be replicated, has resolved prior to attendance, or results from operator error), the visit will remain chargeable at applicable call-out and labour rates.

8.4 Remote Diagnosis

Where possible, Astell will attempt remote diagnosis prior to arranging an on-site attendance in order to minimise disruption and cost to the Customer. Remote diagnosis does not guarantee that a physical attendance will not subsequently be required.

9. Spare Parts Supply

9.1 Genuine Parts

• Direct to the Customer for self-installation (where Astell considers self-installation appropriate and safe for the part in question).
• During a service visit by an Astell engineer.
• Via Astell's UK or international distribution network.

9.3 International Supply

Astell supplies spare parts internationally. International customers are responsible for all import duties, customs clearance, local taxes and any regulatory requirements applicable to parts shipment in their jurisdiction.

9.4 Retention of Title

All spare parts supplied by Astell remain the property of Astell until payment is received in full. Until title passes, the Customer shall hold the parts on behalf of Astell, keep them identifiable as Astell's property, and not dispose of, pledge or otherwise encumber the parts. Risk in the parts passes to the Customer on delivery.

9.5 Parts Availability

11.3 PSSR Compliance

The Customer, as user and/or owner of the Equipment, carries legal responsibility for compliance with the Pressure Systems Safety Regulations 2000 (PSSR). This includes maintaining a valid Written Scheme of Examination (WSE) for each qualifying pressure system, ensuring periodic thorough examinations are carried out by a competent person, and keeping records as required. Astell does not act as a competent person under PSSR unless explicitly contracted to do so in writing.

11.4 Data and Records

The Customer is responsible for maintaining their own copies of all calibration certificates, validation reports and service records. Astell will retain service records for a minimum of ten (10) years from the date of the relevant service activity, but this does not relieve the Customer of their own record-keeping obligations.

11.5 Postponement and Cancellation

At least two (2) Working Days' notice should be provided to cancel or postpone a scheduled service visit. Astell reserves the right to charge a cancellation or abortive visit fee where insufficient notice is given or where an engineer is unable to carry out work due to factors within the Customer's control.

12. Charges and Payment

Astell may use anonymised, aggregated Service data for internal performance analysis and quality improvement purposes.

18. Data Protection

Astell will process any personal data collected in connection with the Services in accordance with applicable data protection legislation, including the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018. Astell's Privacy Notice is available on request or at astell.com. The Customer warrants that it has the necessary authority to share any personal data provided to Astell in connection with the Services.

19. Force Majeure

Neither party shall be in breach of these Terms or liable to the other for any failure or delay in performing its obligations where such failure or delay results directly or indirectly from a Force Majeure Event. The affected party shall notify the other as soon as reasonably practicable and shall use reasonable endeavours to mitigate the effects and resume performance. Where a Force Majeure Event affecting Astell continues for more than sixty (60) days, either party may terminate the affected arrangement on written notice, save that the Customer shall pay for all Services actually performed up to the date of termination.

20. Termination

20.1 Termination for Cause

Either party may terminate a Service Contract or specific service arrangement immediately by written notice if the other party commits a material breach and (where remediable) fails to remedy it within fourteen (14) days of written notice, becomes insolvent or enters any analogous insolvency process, or ceases or threatens to cease to carry on business.

20.2 Consequences of Termination

Upon termination, all sums owing by the Customer shall become immediately due and payable, the Customer shall return or destroy any Astell Confidential Information in its possession, and any clauses that by their nature ought to survive termination shall continue in force.

21. General Legal Provisions

21.1 Governing Law and Jurisdiction

These Terms and Conditions shall be governed by and construed in accordance with the laws of England and Wales. The parties irrevocably submit to the exclusive jurisdiction of the courts of England and Wales for the resolution of any dispute, save that either party may seek urgent injunctive relief in any court of competent jurisdiction.

21.2 Dispute Resolution
