前言
国际标准化组织 (国际标准化组织) 是国家标准机构的全球联盟 (ISO成员机构). 国际标准的制定通常通过ISO技术委员会进行. 对已成立技术委员会的主题感兴趣的每个成员机构都有权在委员会中派代表参加. 与标准化组织联络的政府和非政府国际组织也参与了这项工作. ISO 与国际电工委员会密切合作 (国际电工委员会) 关于电气标准化的所有问题.

用于制定本文件的程序以及用于进一步维护的程序在第 1 部分中进行了描述。 1 ISO/IEC 指令的. 尤其, 应注意不同类型ISO文件所需的不同批准标准. 本文件根据部分编辑规则起草 2 ISO/IEC 指令的 (请参阅 iso.org/directives).

介绍
Sampling depends on the size of the product and container, but not on the type of product, 比如油漆, 清漆, paint powders, 粘合剂, 颜料, fillers or solvents. 国际标准化组织 1513 specifies procedures for the preliminary examination of individual samples received and for the preparation of test samples by mixing and reducing a series of samples representing a batch of paints, 清漆或相关产品. Samples of the product to be tested have been collected in accordance with this document.

Correct sampling is the basis for subsequent tests and their results. Operators with the required knowledge and experience need to perform the various sampling procedures with great care. The general instructions in this document are intended to complement this knowledge and experience and apply to most situations. 然而, some products may require special sampling precautions not provided in this document; 所以, operators need to be particularly vigilant to pay attention to any abnormal characteristics exhibited by these products. Operators should be aware of product specifications and national safety regulations that may require special precautions.

1 范围
The document specifies procedures for sampling paints and varnishes, including paint powders, and raw materials used in their manufacture. Such products include liquids and materials that are not chemically modified and can liquify when heated, as well as powders, granules and pastes. Samples may be taken from containers, such as cans, barrels, tanks, tank cars or ship tanks, or from barrels, sacks, large bags, silos or silo cars or conveyors.

This document does not address sample preparation for testing or reducing samples thus collected, which is covered in ISO 1513.
