On June 26, 2013, the National Automobile Products Industry Federation, the National Automotive Standardization Technical Committee Body Attachment Subcommittee and Guangdong Dongjian Group jointly issued the industry standard for China's "Car Protection Bar". This standard was drafted by Guangdong Dongjian Group. Many domestic research institutes and professional institutions participated in the demonstration and passed the examination and approval of the Ministry of Industry and Information Technology. It is reported that the official announcement of China's "automobile protection bar" industry standard marks a breakthrough in the "zero" industry standard for car protection bars, filling the gap in domestic standards. The standard will be officially implemented nationwide on September 1, 2013, causing great concern to industry manufacturers and distributors.
