1.1 使用1到5的色阶，本规程描述了测定未染色尼龙或用阳离子可染上浆剂制备的非阳离子可染聚酯纱线制成的织物中上浆的存在和相对量的程序 1.2 经买方和供应商同意，可使用本标准中规定以外的程序和仪器，具体偏离报告中承认的标准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 根据本规程，染色织物的颜色深度与织物上浆量有关。本规程采用1到5的染色等级，该等级与织物上浆的相对量成反比。浅色染色表示上浆浓度低，并保证较高的数值评级，而深色染色表示上浆浓度高，并保证较低的数值评级。 5.2 本规程的准确性取决于测试人员将着色剂的颜色与AATCC 9步色度转移量表中的颜色相匹配的能力。

1.1 Using a color scale of 1 to 5, this practice describes the procedures for determining the presence and relative amount of sizing in fabrics made of undyed nylon or non-cationically dyeable polyester yarns prepared with a cationically dyeable sizing 1.2 Procedures and apparatus other than those stated in this standard may be used by agreement of purchaser and supplier with the specific deviations from the standard acknowledged in the report. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The depth of color achieved in dyeing fabric according to this practice is relative to the amount of sizing in the fabric. This practice employs a chromatic staining scale from 1 to 5 which is inversely proportional to the relative amount of sizing in the fabric. A light color stain indicates a low concentration of sizing and warrants a high numerical rating, while a dark color stain indicates a high concentration of sizing and warrants a low numerical rating. 5.2 The accuracy of this practice depends upon the ability of the testing personnel to match the color of the stain to the colors in the AATCC 9 Step ChromaticTransference Scale.
