Technical Insights

In examining these five new standards, several shared technical requirements and best practices emerge:

• Conformity Assessment: Both PE piping (CEN/TS 12201-7) and modern valve/actuator standards emphasize the necessity of integrating testing regimes—type, batch, and audit—directly into the QMS, with robust documentation to enable traceability and third-party certification.

• Performance Testing: VRF heat pumps and HVAC systems (ISO 18107) mandate precise laboratory setups, climate-specific test cycles, and controlled reporting procedures; valve gearboxes (ISO 22109) require defined endurance and structural tests.

• Mechanical Interfaces: Valve actuator attachment (ISO 5210, ISO 5211) demands strict adherence to dimensional standards and specified tolerances for flanges, keyways, and spigots, supporting interchangeability and safety.

Best practices for implementation

1. Conduct a gap analysis – Compare current equipment designs and supplier specs to new requirements.
2. Engage with accredited test labs and certification bodies early for products or systems where conformity declaration is essential.
3. Update procurement and supplier qualification processes to align with standard nomenclature and documentation expectations.
4. Train design, engineering, and QA/QC staff on revised procedures, especially regarding new materials (like PE100-RC) or mechanisms (e.g., new gearbox classes).
5. Implement periodic review cycles to keep pace with further revisions, ensuring ongoing compliance.

Certification and testing recommendations

• Utilize accredited laboratories with recognized traceability for product and batch testing
• Maintain comprehensive documentation, including audit trails and test records
• Engage in industry working groups or user communities to stay informed of best practices and updates
