2 Standard Documents Need to Conform to Claim Conformity to the Quality Requirements
2.1 General principles
To claim conformity to the quality requirements of GB/T 12467.2, GB/T 12467.3 and GB/T 12467.4, the product standards of a manufacturer is required to conform either to the standards listed in 2.2 or to other standards that provide technically equivalent conditions.
