Communication cables - Part 2-25: Common design rules and construction - Polypropylene insulation compounds
N EN 50290-2-25
Annotation
This European Standard gives specific requirements for PP compounds to be used for multi-element metallic data cables for indoor application. Type 1 is typically a copolymer with better low temperature properties. Type 2 is typically a homopolymer with superior hardness giving better crush resistance.
Using compound and type test data as outlined in this standard, the compound supplier will have sufficient data to demonstrate compliance and warrant that the material is suitable for the specified application.

Коммуникационные кабели - Часть 2-25: Общие правила проектирования и конструкция - составные объекты изоляции Полипропилена
Этот европейский стандарт дает определенные требования для составных объектов PP, которые будут использоваться для многоэлементных металлических кабелей для передачи данных для внутреннего приложения. Тип 1 обычно является сополимером с лучшими низкими температурными свойствами. Тип 2 обычно является homopolymer с превосходящей твердостью, дающей, лучше сокрушают сопротивление.
