抽象化

The specification defines the requirements for the composition, 物理的特性, ガッシュ顔料の性能と表示. 顔料, carriers and additives are included here, including requirements for pigment identification, light fastness and consistency. This article lists some pigments that meet the light resistance requirements in this manual. 加えて, in order to identify other pigments that meet these requirements, instructions for test sample preparation and corresponding test methods for determining relative light resistance are given. Conditions that are not covered in this manual that affect gouettes are substrate, 環境条件, ストレージ, carrier, 顔料, additives, inert gases, サンプルの準備, coarse particles, dispersion fineness, 一貫性, freeze-thaw stability, 等.

意味と使い方

4.1 This specification sets out quality requirements and provides a basis for consensus among producers, distributors and users.

4.2 Not all compliant coatings are the same in all respects, nor are they uniform. Changes in manufacturing (not covered by this specification) may cause some artists to prefer one brand over another, either of which may be accepted under this specification.
