This document has been prepared by the ISO/TC 256 Technical Committee on Pigments, Dyes and Fillers.

The first version of ISO 1247-1, 与 ISO 一起 1247-2, 取消并取代了技术修订后的ISO 1247-1974. It also incorporates the amendment to ISO 1247-1974 /Amd 1:1982.

The main changes from the previous edition are as follows:

— An introduction is added, explaining the reason for the division;

– The addition of a third article, 术语和定义, and the inclusion of terms such as “non-volatile substances” 和 “masking power”;

– The distinction between surface treated and surface untreated aluminium pigments is introduced in articles 4 和 5;

— “Class” in paragraph 4.2 is deleted;

— Change “105°C volatile substance” 到 “non-volatile substance”;

— The original article 6 “包装” is deleted;

– Article 7, 采样, has been reduced to a reference to ISO 15528;

– In Table 1, requirements and test methods of “specific surface area of pigment”, “particle size distribution” 和 “遮盖力” and corresponding test methods are added and renamed as “要求及测试方法”;

— The test method of “锰” is deleted from the metal impurities in Table 1;

Flame atomic absorption spectrometry was introduced to determine metal impurities.

— The original article 13 “unregulated blade force test” is deleted;

– 桌子 3, the test section, 已被删除;

— Article 16 was added to determine concealment force;

— The normative references have been updated, and the texts have been edited and revised.

介绍
Since the beginning of the new millennium, with advances in technology and product development, new aluminum pigments have flourished, and these aluminum pigments are used in a wide range of industrial sectors as heat or rust resistant coatings or colorants. Aluminium pigments can be conveniently divided into two groups according to their form: general aluminium pigments produced during milling and vacuum metallized aluminium pigments (VMPS) (参见 ISO 1247-2). Because of the different technical requirements for aluminium pigments used in different fields, it is necessary to develop an international standard for each of these two groups.

To meet the needs of the marketing of aluminium pigments, this document describes the characteristics of “particle size distribution” 和 “遮盖力” and their corresponding testing methods.

ISO 1247-1-21st 油漆用铝颜料 – 部分 1: 通用铝颜料

To improve the safety of aluminium pigments, low flash point organic solvents and additives have been replaced by high flash point reagents, “105°C volatile substances” has been replaced by “non-volatile substances”, and test methods have been developed in accordance with ISO 3251.

The previous edition (IE. 国际标准化组织 1247:1974) used different spectrophotometric methods for the determination of lead, iron and copper content, and ethylenediamine tetraacetic acid (EDTA) titration for the determination of zinc. These methods are cumbersome to operate. The method used to determine lead involves the use of potassium cyanate, a highly toxic agent rarely used since the 1990s. The method used to determine zinc is only suitable for samples with a total zinc content of 0.10% or more and is not suitable for the current status of the aluminum pigment industry. While these old methods are retained in this document, flame atomic absorption spectrometry is introduced as a new option for the determination of the above-mentioned metal impurities. This method is faster, easier to operate, has a wider detection range, and is becoming increasingly popular.

In order to use as few toxic agents as possible, this document uses 2-butoxy-ethyl alcohol or n-butyl acetate instead of acetone, which is now banned or restricted in many countries as a material that can be used in the manufacture of illicit drugs.

就本文件而言, ISO 中给出的术语和定义 18451-1, 国际标准化组织 18451-2 并且以下文章适用.

3.1 Non-volatile substances

Mass residue obtained by evaporation under specified conditions

笔记 1: In place of the term “non-volatile substance”, different terms such as solids, dry residues, dry matter, solid matter, baking residues are often used together with their respective abbreviations. 期限 “non-volatile substances”, which is also applicable in ISO 3251, should be used with the abbreviation “NV” instead of these terms.
