Give guidance for value-based decision-making

Interpretation guidelines are given in BS EN IEC 60034-27-1 and are applicable only if all the following requirements are fulfilled:

The Hot Set cable test is a straightforward means of determining if the material used in insulation or sheathing has been sufficiently cross-linked

Plastics. Polyamides. Determination of e-caprolactam and w-laurolactam by gas chromatography Ingestion-build-47934 BS EN 1422 outlines requirements1 Scope This International Standard specifies a method for determining caprolactam and laurolactam in polyamides by gas chromatography. It is suitable particularly for the determination of caprolactam in polyamide 6 and laurolactam in polyamide 12. Bearing in mind that gas chromatography offers a wide range of possible conditions, the method specified is that shown to have been suitable in practice. Two variants of the basic method are specified:
