AS/NZS 1462 Methods For test of plastics pipes and fittings

Part 1: Methods of test for plastics pipes and fittings - Method for determining the dimensions of pipes and fittings

Part 4: Methods of test for plastics pipes and fittings - Method of determining reversion of UPVC pipes

Part 8: Methods of test for plastics pipes and fittings - Method of testing the leak tightness of assemblies

Part 13: Methods of test for plastics pipes and fittings - Method for the determination of elastomeric seal joint contact width and pressure

Part 22: Methods of test for plastics pipes and fittings - Method for the determination of pipe stiffness

Part 23: Methods of test for plastics pipes and fittings - Method for determination of ring flexibility

Part 25: Methods of test for plastics pipes and fittings - Determination of slow-crack-growth of PE (polyethylene) resins - Notched, constant ligament-stress (NCLS) method

AS/NZS 1462.1 sets out a method for determining the dimensions of plastics pipes and fittings (i.e. outside diameter, wall thickness, length, squareness of pipe ends and internal length, mouth diameter and root diameter of sockets).

AS/NZS 1462.4 sets out the method for determining the degree of residual extrusion stress in plastic pipes by immersion in a heat transfer medium or exposure in a hot air oven. Temperatures of test, times of immersion/exposure and specifications for degree of residual stress shall be as specified in the relevant product standard.

AS/NZS 1462.8 specifies a method for testing the leak tightness of assemblies of plastics pipes and fittings with elastomeric sealing-ring socket joints or inspection openings that may be subject to diametric distortion and/or angular deflection. It includes, but is not limited to -

  1. single sockets on pipes,
  2. double sockets,
  3. sockets on fittings, and
  4. inspection openings on fittings.

It is also applicable to elastomeric sealing-ring sockets made of other materials, e.g. ductile iron, intended for use with plastics piping.

AS/NZS 1462.13 sets out a procedure for determining the contact width and contact pressure profile of an elastomeric seal joint. It allows for both spigot-mounted and socket-mounted elastomeric seal joints.

AS/NZS 1462.22 sets out a procedure for determining the pipe stiffness of PVC pipes with structured walls.

AS/NZS 1462.23 sets out a procedure for determining the ring flexibility of plastics pipes with structured walls.

AS/NZS 1462.25 sets out a method to determine the susceptibility of polyethylene resins to slow-crack-growth under a constant ligament-stress in an accelerating environment.

This test method is intended as an index test to assess slow-crack-growth (SCG) resistance for PE compounds. It measures the failure time associated with a given test specimen at a constant, specified, ligament-stress level.
