标准摘要
[中文适用范围]： ISO 16365的这一部分规定了酯类的测定方法，包括酯类热塑性聚氨酯(TPU)和醚类TPU，用于质量控制，无需复杂的仪器，并避免或最大限度地减少对TPU材料的长期微生物测试。 所描述的方法用于区分主要 TPU 类型并表征 TPU 混合物。 该方法适用于所有基于 4,4'-二苯基甲烷二异氰酸酯 (MDI) 的线性聚氨酯，旨在最大限度地减少与微生物耐受性和水解相关的长期测试。 [外文原描述]： ISO 16365-3:2014 specifies a method for the determination of esters including ester thermoplastic polyurethanes (TPU) and ether TPU for quality control without the necessity of sophisticated instrumentation and avoids or minimizes long-term microbial testing for TPU materials. The method described is used to distinguish major TPU types and characterize TPU mixtures. The method is applicable to all linear polyurethanes based on 4,4'-diphenylmethane diisocyanate (MDI) and is intended for instance to minimize long-term tests related to microbe resistance and hydrolysis.
