Recently, China National Center for Quality Supervision and Test of Standard Parts, with another four companies, formed a working group to develop standards for ball/ roll-pin antitheft nut. The four companies are Zhe Jiang Long You Kang Long Circuit and Line Equipment Industry Co., Ltd., Zhejiang Aide Power Fittings Manufacturing Co., Ltd, Guangdong Zisheng Power fittings Manufacturing Co., Ltd. and Hebei Xinde Fittings.
The draft of the standards was finished and got approved by Standardization Administration of the People's Republic of China (SAC) in 2007 and was listed in the fifth batch of amendments to the national standard system plan. To make the work more efficient, scientific and comprehensive, the Centre set up the standard-setting group. The national standard is expected to be completed in October 2008.
