BS EN ISO 11337:2023 - TC
This standard BS EN ISO 11337:2023 - TC Tracked Changes. Plastics. Polyamides. Determination of ε-caprolactam and ω-laurolactam by gas chromatography is classified in these ICS categories:
83.080.20 Thermoplastic materials
This document specifies a method for determining ??caprolactam and ??laurolactam in polyamides by gas chromatography. It is applicable particularly to the determination of ??caprolactam in polyamide 6 and ??laurolactam in polyamide 12. Two variants of the basic method are specified. — Method A is an extraction method with boiling methanol, and the extract is injected into a gas chromatograph. — Method B is a method using a solvent, and the solution is injected into a gas chromatograph.
