标准摘要
[中文适用范围]: 1.1 声暴露是一个物理量,通过瞬时频率加权声压平方的时间积分,考虑了给定位置的声音压力及其持续时间。 1.2 本国际标准适用于测量由稳态、间歇、波动、不规则或脉冲声音产生的A频率加权声暴露的仪器。符合本标准规范的仪器旨在佩戴在人身上测量声暴露。工作场所的声暴露测量可能有助于根据ISO 1999和ISO 9612确定职业噪声暴露。 1.3 本标准规定了个人声暴露仪器的声学和电气性能要求,适用于一个精度等级。该精度等级对应于符合IEC 60804类型2要求的积分声级计,适用于A加权声压级范围为80 dB至130 dB,标称频率范围为63 Hz至8 kHz。 1.4 仪器性能与设计目标偏差的容差代表了实际仪器的性能能力。个人声暴露仪器要求在规定的环境条件范围内在本标准的容差范围内运行。 [外文原描述]: IEC 61252:1993+A1:2000+A2:2017 applies to instruments for measurement of A-frequency-weighted sound exposure resulting from steady, intermittent, fluctuating, irregular, or impulsive sound. Specifies acoustical and electrical performance requirements for personal sound exposure meters of one accuracy grade. This consolidated version consists of the first edition (1993), its amendment 1 (2000) and its amendment 2 (2017). Therefore, no need to order amendment in addition to this publication.
