QB/T2212.5-1996
This standard is revised on the basis of the former professional standards of the Ministry of Light Industry ZBJ47001--1985 "Terms of Construction (Masonry) Tools", ZBJ47002--1985 "General Technical Conditions of Construction (Masonry) Tools", and ZBJ47003--1985 "Inspection Rules, Marking, Packaging and Transportation of Construction (Masonry) Tools", and converted into the light industry standard. In the overall structure of the standard, the terminology, general technical conditions and product standards of construction tools are retained, and the original ZBJ47003-1985 "Inspection Rules, Marking, Packaging and Transportation of Construction (Masonry) Tools" are cancelled, and some of its relevant provisions are merged into the general technical conditions. The product standards are retained according to the numbers in the terms, and the product standard of "Diamond Grinding Shovel" is added. This standard changes the word "brick" in the brackets of the original name to "brick type", and puts it behind the standard name "construction tools", so that the hand tools used in construction work are more standardized, and a clear limitation is made in the applicable scope. This standard is a supporting standard, and the terminology and general technical conditions are based on it. The technical content in the original standard that has been proven to be suitable for my country's situation is retained. The main dimensions in the product standard have been optimized, several specifications have been added, and the limit deviation has been indicated. This standard has modified and improved some quality indicators.
From the date of implementation of this standard, ZBJ4700147003--1985 will be abolished at the same time. This standard is proposed by the Quality Standard Department of China Light Industry Association. This standard is under the jurisdiction of the National Tool Hardware Standard Promotion Center. The drafting units of this standard are: Shanghai Tool Industry Research Institute, Shijiazhuang Industrial and Agricultural Machinery Factory, Dalian Housing Equipment Tool General Factory, Shanghai Fengxian Gongzhen No. 3 Factory, etc.
The main drafters of this standard are: Cheng Yongfeng, Zuo Zhenjiang, Tian Limin, Qin Delin, Wang Chende. This standard is entrusted to the National Tool Hardware Standardization Center for interpretation. 596
