CE標準解讀：EN ISO 1183-1《塑料 - 非泡沫塑料密度的測定方法 - 第 1 部分》

This document specifies three methods for the determination of the density of non-cellular plastics in the form of void-free moulded or extruded objects, as well as powders, flakes and granules. a€” Method A: Immersion method, for solid plastics (except for powders) in void-free form. a€” Method B: Liquid pycnometer method, for particles, powders, flakes, granules or small pieces of finished parts. a€” Method C: Titration method, for plastics in any void-free form. NOTE Density is frequently used to follow variations in physical structure or composition of plastic materials. Density can also be useful in assessing the uniformity of samples or specimens. Often, the density of plastic materials depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation method are intended to be included in the appropriate material specification. This note is applicable to all three methods.

本文件規定了測定無空隙模制或擠出物體以及粉末、薄片和顆粒形式的非泡沫塑料密度的三種方法。 – 方法 A：浸泡法，適用于無空隙的固體塑料（粉末除外）。 – 方法 B：液體比重瓶法，適用于顆粒、粉末、薄片、顆粒或小塊成品零件。 – 方法 C：滴定法，適用于任何無空隙形式的塑料。 注：密度經常用于跟蹤塑料材料的物理結構或成分的變化。 密度還可用于評估樣品或樣本的均勻性。 通常，塑料材料的密度取決于樣品制備方法的選擇。 在這種情況下，樣本制備方法的細節應包含在適當的材料規范中。 本注釋適用于所有三種方法。
