Scope
This standard specifies the classification and evaluation method of product quality grades for hydraulic CY type axial piston pumps. 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 mass-produced products, and does not perform grading evaluation for one-off variant products and special products.
