SIST EN 12201-3:2011/kFprA1:2012

Overview

EN 12201-3:2011/FprA1 is the CEN draft amendment to EN 12201-3:2011 covering polyethylene (PE) fittings for plastics piping systems used in water supply and drainage and sewerage under pressure. Prepared by Technical Committee CEN/TC 155, this final draft amendment (FprA1, May 2012) introduces a targeted technical change to the standard’s requirements for mechanical testing. Note: as a draft amendment it is subject to review and is not a final European Standard until formally adopted.

Key topics and technical requirements

• Scope focus: Polyethylene (PE) fittings for pressurized water distribution and external sewerage systems (EN 12201 series - Part 3: Fittings).
• Amendment summary: The amendment modifies Subclause 7.3 (Requirements) and specifically updates Footnote c in Table 4 - Mechanical characteristics.
• Test pressure calculation: The previous sentence about stress calculation is replaced. The new requirement states: "The test pressure shall be calculated using the design SDR of the fitting."
• Standards governance: The amendment was prepared by CEN/TC 155 and provided in English, French and German for the unique acceptance procedure across CEN member bodies.
• Classification codes: Relevant ICS references include 23.040.45 (plastic fittings), 91.140.60 (water supply systems) and 93.030 (external sewage systems).

Practical applications and users

This amendment and the EN 12201-3 standard are directly relevant to:

• Product manufacturers of PE fittings who must design and test fittings to comply with mechanical characteristic requirements.
• Test laboratories and quality assurance teams that calculate and apply test pressures during type testing and certification.
• Design engineers and specifiers writing procurement documents and ensuring system components meet harmonized European testing rules.
• Contractors and asset owners responsible for pressurized water distribution or sewerage collection systems seeking compliant components.
• Regulatory and standards bodies monitoring conformity and incorporation of amendments into national standards.

Related standards

• EN 12201 series (polyethylene piping systems) - Part 3 is the dedicated part for fittings; related parts of the series cover pipes, joints and system performance (consult the EN 12201 family for full system requirements).
• Draft amendment status means national bodies will incorporate the change into their national versions following CEN/CENELEC internal regulations once approved.

This amendment emphasizes consistent, design-based test pressure calculation (using the fitting’s design SDR) to align mechanical testing with the intended structural dimensions of PE fittings.
