标准范围

本文件规定了测定玻璃增强塑料的纺织玻璃和矿物填料含量的两种煅烧方法:—？方法？答:用于在不存在矿物填料时测定纺织品玻璃含量。—？方法？B:当两种成分都存在时，用于测定纺织品-玻璃和矿物-填料含量。本文件适用于以下类型的材料:—？由纱线、粗纱、带或织物制成的预浸料；—？SMC、BMC和DMC模塑料；—？纺织品-玻璃增强热塑性模塑材料和颗粒；—？用热固性或热塑性树脂制成的填充或未填充的纺织玻璃层压板。这些方法不适用于以下类型的增强塑料:—？含有纺织玻璃以外的增强材料的那些；—？含有在测试温度下不完全烧掉的材料的那些(例如，基于有机硅树脂的那些)；—？含有在低于最低煅烧温度的温度下降解的矿物填料的那些。

This document specifies two calcination methods for the determination of the textile glass and mineral filler content of glass-reinforced plastics:

—     Method A: for the determination of the textile glass content when no mineral fillers are present.

—     Method B: for the determination of the textile-glass and mineral-filler content when both components are present.

This document is applicable to the following types of material:

—     prepregs made from yarns, rovings, tapes or fabrics;

—     SMC, BMC and DMC moulding compounds;

—     textile-glass-reinforced thermoplastic moulding materials and granules;

—     filled or unfilled textile-glass laminates made with thermosetting or thermoplastic resins.

The methods do not apply to the following types of reinforced plastic:

—     those containing reinforcements other than textile glass;

—     those containing materials which do not completely burn off at the test temperature (for example, those based on silicone resin);

—     those containing mineral fillers which degrade at temperatures below the minimum calcination temperature.
