ASTM D5215测试标准

ASTM D5215是烯基地板用胶黏剂着色的仪器评定的试验法，本标准是于1993年被采用，并且于2012年重新复审的：

1.1ASTM D5215描述准确测量由于接触胶粘剂而发生在乙烯基地板染色程度的过程和方法。乙烯基地板样品接触胶粘剂和未接触到粘合剂之间颜色差异可以从CIELAB颜色刻度测得。

1.2本试验方法提供了可能出现的乙烯基地板接触胶粘剂染色过程中的视觉评价。

ASTM D5215英文简介

Significance and Use

Certain substances in adhesives may cause discoloration of vinyl flooring. This test method provides a means of measuring the discolorations that may occur in the vinyl as a result of contact with these adhesives. Vinyl flooring specimens, either contacting or not contacting the adhesive, are exposed to heat and UVA light to accelerate discoloration. By means of colorimeter or spectrophotometer, color differences between exposed specimens are accurately measured. Therefore, instrumental evaluation rather than personal subjective evaluation is used to determine the amount of discoloration an adhesive may produce in vinyl flooring. This test method does not attempt to simulate or duplicate the heat and sunlight conditions that may impact vinyl floor coverings while in service.

1. Scope

1.1 This test method describes procedures and instrumentation for accurately measuring the degree of staining that may occur in vinyl flooring as a result of its contact with adhesives. Measured color differences between vinyl flooring specimens contacting the adhesive and not contacting the adhesive are expressed in the CIELAB Color-Scale System.

1.2 This test method provides for visual evaluation of staining which may occur when vinyl flooring contacts adhesives.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
