QB/T2210-1996
This standard is formulated on the basis of the former Light Industry Ministry Standard SG226-1981 "Hand-made Drill". This standard supplements the product type and makes corresponding adjustments to its basic dimensions. The inspection rules of the product adopt the sampling method specified in GB/T2828-1987 "Batch Inspection Count Sampling Procedure and Sampling Table (Applicable to Continuous Batch Inspection)", and further improve the product packaging, marking, transportation and storage requirements in accordance with the provisions of GB/T5305-1985 "Packaging, Marking, Transportation and Storage of Hand Tools".
This standard will replace SG226-1981 from the date of implementation. This standard is proposed by the Quality Standards Department of the China Light Industry Federation. This standard is under the jurisdiction of the National Tool Hardware Standardization Center. The responsible drafting unit of this standard: Shanghai Tool Industry Research Institute; participating drafting unit: Shanghai Automobile Tool Factory. The main drafters of this standard: Lin Meide and Wang Wei. 580wwW.bzxz.Net
