1.范围1。1本标准概述了一种确定暴露在模拟土壤中对模制和/或预制制品、管材、棒材、板材和薄膜形式的塑料性能影响的方法。视觉、化学和机械性能的变化可通过适用的方法确定（见附录A）。1.2本标准是塑料评级的定性测试程序，要求对视觉效果进行主观解释。1.3本标准并非旨在解决与其使用相关的所有安全问题。用户有责任建立适当的安全和健康- 使用本标准前的相关措施和任何监管限制。1.4以SI（公制）单位给出的数值为标准。括号中给出的值仅供参考。

1. Scope1.1This Standard outlines a method for determining the effect of exposure to a simulated soil on the properties of plastics in the form of moulded and/or fabricated articles, tubes, rods, sheets, and film. Changes in visual, chemical, and mechanical properties may be determined by the applicable method (see Appendix A).1.2This Standard is a qualitative test procedure for the rating of plastics and calls for somewhat subjective interpretation of visual effects.1.3This Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user to establish appropriate safety and health-related measures and any regulatory limitations prior to use of this Standard.1.4The values given in SI (metric) units are the standard.The values given in parentheses are for information only.
