1 范围和目的 IEC721的这部分标准研究自然界中出现的环境条件,特别涉及地震振动与冲击的条件。 目的在于确定产品在贮存和使用期间可能遭受到的表征地震特性的一些基本性质与参数严酷程度用的背景材料。规定的加速度值仅用于地表条件。涉及与建筑物有关的条件,但仅限于一般情况的描述。 2 标准的依据 构成IEC721中的这部分内容,全部包括在本标准中。一俟颁布,版本就生效。各个标准修订再版时,要与IEC721的这部分保持一致关系,并要研究应用下面列出标准的最新版本的可能性。IEC和ISO的会员应持有目前有效国际标准的登记册。
1 Scope and purpose This part of IEC721 standard studies the environmental conditions that occur in nature, with particular reference to the conditions of seismic vibrations and shocks. The purpose is to determine some of the basic properties and harshness of the seismic characteristics that may be encountered during storage and use of the product. The specified acceleration values are for surface conditions only. It refers to the conditions related to the building, but it is limited to the general description. 2 standards based on the composition of this part of IEC721, all included in this standard. Once promulgated, the version will take effect. Revision of each standard revision, to be consistent with this part of IEC721, and to study the possibility of applying the latest version of the standard listed below. Members of IEC and ISO should have registries of currently valid international standards.
