NF EN ISO 580
Plastics piping and ducting systems - Injection-moulded thermoplastics fittings - Methods for visually assessing the effects of heating
ISO 580:2005 specifies two methods for assessing the effects of heating on injection-moulded thermoplastics pipe fittings -- method A, using an air oven, and method B, using a liquid bath. In case of disagreement, method A is the reference method. ISO 580:2005 is applicable to cement-welded fittings as well as to flanged fittings and fittings incorporating elastomeric seals and to fittings consisting of the assembly of several moulded parts (e.g. union connectors). It is applicable to both pressure and non-pressure fittings.
