Scope
This standard specifies the classification and evaluation methods for the quality grades of gear pumps with pressures of 2.5MPa and 10~25MPa. This standard is a unified regulation for measuring the grade level of product quality (including design quality and manufacturing quality), and is the basis for assessing product quality, product grading, enterprise upgrading, and high-quality products with high prices. This standard applies to products produced in batches. For one-time produced variant products and special products, grading evaluation is not performed. The quality assessment of technology-introduced products shall be carried out according to the introduction requirements or contracts, but the product quality grade shall be evaluated according to this standard.
本标准规定了压力为2.5MPa、10～25MPa 齿轮泵产品质量等级的划分和评定方法。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，是考核产品质量、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产品。对于一次性生产的变型产品和专用产品不作分等评定。对技术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。
