纺织玻璃增强塑料 预浸料、模塑料和层压板 煅烧法测定纺织玻璃和矿物填料含量

[中文适用范围]： 本文件规定了两种用于测定玻璃增强塑料中纺织玻璃和矿物填料含量的煅烧方法： — 方法 A：用于测定无矿物填料时的纺织玻璃含量。 — 方法 B：用于测定两种成分均存在时的纺织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、胶带或织物制成的预浸料； — SMC、BMC 和 DMC 模塑化合物； — 纺织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： — 含有除纺织玻璃以外的增强材料的塑料； — 含有在测试温度下不会完全燃烧的材料的塑料（例如，基于硅树脂的塑料）； — 含有在低于最低煅烧温度的温度下降解的矿物填料的塑料。 注：对于这些材料，可以使用 ISO 11667。 [外文原描述]： 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.
