Adaptor fittings for use with plastics and multilayer pipes may combine press ends with fitting ends defined in the other parts of EN 1254.
Press fittings for use with plastics and multilayer pipes may also have flanged end connections according to EN 1092-3.
Press fittings for use with plastics and multilayer pipes may also have a plated or other decorative surface coating.
Fittings can be produced by machining, metal forming, casting, or fabrication.
Products covered by this document are intended to be used in:
a) liquid applications:
- hot, cold or combined hot and cold water, including systems according to EN 806;
- closed heating systems according to EN 12828;
- cooling systems;
- drainage systems;
- fire protection systems including sprinkler systems according to EN 12845;
- supply systems for points of consumption with liquid fuels according to EN 12514.
b) gas applications:
- natural gas and liquefied petroleum gas systems with a maximum operating pressure less than or equal to 5 bar according to EN 1775;
- compressed air systems.

Overview

SIST EN 1254-8:2021/oprA1:2024 is a European standard developed by CEN that specifies requirements for press fittings made from copper and copper alloys designed for use with plastics and multilayer pipes in plumbing systems. This standard defines the product characteristics, assessment methods, and conformity criteria for fittings with radial and axial press ends, covering nominal diameters ranging from 10 mm to 160 mm. These fittings are engineered for a service lifetime of up to fifty years, ensuring long-term reliability in various applications.

This amendment (prA1:2024) updates normative references, introduces wall thickness requirements for copper alloy fittings used in specific piping systems, and refines testing and conformity evaluation processes to align with the latest industry practices.

Key Topics

• Material Specifications: Applies to copper alloys listed in CEN/TS 13388, including variants suitable for press fittings.
• Fitting Types: Covers radial and axial press fittings, adaptor fittings combining press ends with other EN 1254 parts, and fittings with flanged connections compliant with EN 1092-3.
• Surface Finishes: Allows for fittings with plated or other decorative coatings.
• Manufacturing Methods: Includes machining, metal forming, casting, or fabrication methods.
• Wall Thickness Requirements: Newly introduced in the amendment for fittings used with systems under EN ISO 15874, EN ISO 15875, EN ISO 15876, EN ISO 15877, EN ISO 21003, and EN ISO 22391 series.
• Testing and Assessment: Specifies detailed procedures for evaluating wall thickness and other product characteristics using precise instruments like gauges and micrometers.
• Conformity Evaluation: Outlines sampling methods and compliance criteria for assessing product quality based on test results.
