IAPMO IGC 306-2016 Brass Compression Fittings for Multilayer Piping Systems

0 Introduction
This Standard was developed and is intended for the India market.

1 Scope

1.1 General

1.1.1 This Standard covers brass compression fittings for polyethylene/aluminum/polyethylene (PE-AL-PE) and polyethylene/aluminum/cross-linked polyethylene (PE-AL-PEX) composite pressure piping in nominal sizes 1014, 1216, 1620, 2025, 2532, 3240, 4050, 5063, 6375, 7590, and 90110 and specifies requirements for materials, physical characteristics, performance testing, and markings.
Note: The first two digits of the nominal size indicate the approximate inside diameter, in mm, and the following digits indicate the nominal outside diameter, also in mm. For example, a 2025 pipe means the inside diameter is approximately 20 mm (0.75 in) and the outside diameter is approximately 25 mm (1 in).

1.1.2 Compression fittings covered by this Standard have threaded compression nuts and compression split rings or split compression clamp halves with bolts and nuts to effect their internal sealing.

1.1.3 Compression fittings covered by this Standard are intended to be used in hot- and cold-water distribution systems with a rated pressure of 690 kPa (100 psi) at
(a) 95 ºC (203ºF) for PE-AL-PEX pipes; and
(b) 80 ºC (176ºF) for PE-AL-PE pipes.

1.1.4 Compression fittings covered by this Standard are intended to be used in potable water distribution systems for residential and commercial applications, water service, underground irrigation systems, radiant panel heating systems, baseboard, snow- and ice-melt systems, compressed-air piping systems and piping systems for gases that are compatible with the composite pipe and fittings
