The State Administration of Market Supervision and Administration of China and the National Standardization Administration issued seven updates on national standards for fasteners on May 23, 2023 to replace the previous standards. These seven new national standards for fasteners will be implemented on December 1, 2023. This is an important event in the fastener industry. The full implementation of the new standard will continue to improve the technical level of the fastener industry and play an indicator role in improving the quality of fastener products.
Seven standards:
The updated seven standards cover many aspects of fasteners, including acceptance inspection and plating. Among them, there are several standards more than 20 years since the last update.
Of the seven standards, the earliest version was released in 1985, and 38 years have passed since then. In the past nearly 40 years, each standard version of the update is condensed with the wisdom and hard work of the predecessors.
