Scope
This standard specifies the classification and evaluation methods of product quality grades for hydraulic gas-loaded accumulators (hereinafter referred to as accumulators). This standard is a unified regulation for measuring the grade level of product quality (including design quality and manufacturing quality), and serves as the basis for product assessment, product grading, enterprise upgrading, and high-quality and high-price products. This standard applies to accumulators produced in batches; for one-time modified products and special products, grading evaluation is not performed. For the quality assessment of imported products, it shall be carried out according to the import requirements or contracts, but the product quality grade shall be evaluated according to this standard.
本标准规定了液压隔离式蓄能器(以下简称蓄能器)的产品质量等级的划分及评定方法。本标准是衡量产品质量(包括设计质量和制造质量)等级水平的统一规定，是考核产品、产品分等定级、企业升级、产品优质优价的依据。本标准适用于批量生产的蓄能器产品，对于一次性变型产品和专用产品不作分等评定。对于引进产品的质量考核按引进要求或合同进行，但产品质量等级应按本标准评定。
