标准摘要
[中文适用范围]： ADOPTED_FROM:ISO 7574-4:1985 ISO 7574 的这一部分提供了贴标者确定标示值 Lc 的指导原则，并规定了用于验证一批（一批）机器设备的噪声排放是否符合其标示值的统计抽样程序。ISO 7574 的这一部分旨在协助那些负责为特定机器系列起草特定标签规范的缔约方。它也旨在为希望其机器批次符合验证程序的贴标者提供帮助，该验证程序符合基于第 7 条的特定标签规范中给出的规范。ISO 7574 的这一部分不涉及如果未确认一批（一批）机器的标示值已得到验证而产生的后果。 [外文原描述]： Provides guidelines for determining the labelled value by the labeller and specifies statistical sampling procedures for checking compliance of noise emitted of a lot of machines with its labelled value. Does not deal with the consequences that ensue if the specified value is not confirmed as checked for a lot of machines.
