This Standard specifies methods for visually assessing the effects of heating on injection-moulded thermoplastics fittings, including cracking or splitting induced by residual stress. It is applicable to fittings for pressure and non-pressure applications, e.g. flanged fittings, fittings incorporating elastomeric sealing rings and fittings consisting of the assembly of a number of moulded parts. The modifications of ISO 580 are: - no material is mentioned except in annex A, which is informative, concerning the setting of test temperatures and periods for fittings of PVC-U; - the method using a liquid bath is incorporated as a standardized method (method B) as an alternative to the method using an air oven (method A), with the air oven method remaining the reference method; - test parameters, except those common to all plastics, are omitted; - no material-dependent requirements are given; - editorial changes have been introduced.
