This standard specifies the quality grades, test methods, and sampling and evaluation methods for compressor products.
Compressor products are divided into three grades: qualified product, first-class product, and premium product, based on their quality level and use value.
Compressors shall comply with the provisions of JB/T 4359, and the assessment items and indicator requirements for each grade are specified in Table 1.
When measuring vibration during the mechanical running test at the specified speed, either the permissible vibration velocity RMS value at the bearing or the permissible shaft vibration displacement peak-to-peak value near the journal may be met.
The quality grade of a product shall be determined in accordance with all assessment items specified in this standard; otherwise, it shall be graded according to the lowest indicator achieved, and no grade shall be assigned if any item is missing.
