In the fourth quarter of 2013, a quality inspection was conducted on 90 batches of lock products from 90 companies across four provinces and municipalities directly under the Central Government, including Shanghai, Zhejiang, Shandong, and Guangdong. The inspected products included marble mortise locks, ball locks, bicycle locks, and exterior door locks. These products were tested according to relevant standards such as GB 21556-2008 "General Technical Conditions for Lock Safety" and QB 1001-2006 "Bicycle Lock." A total of 12 to 18 items were examined depending on the product type, covering aspects like mutual opening ratio, lock tongue extension length, static load resistance, handle torque, anti-dial safety devices, and more.
The inspection found that 10 batches of products failed to meet the required standards. Issues were identified in several key areas, including the interlocking rate of marble mortise door locks, the mutual opening ratio of external door locks, the protruding length of the lock tongues, axial and lateral static loads, handle torque, and other critical performance indicators. These deficiencies raised concerns about the security and reliability of the affected products.
Following the findings, the General Administration of Quality Supervision, Inspection and Quarantine instructed the relevant provincial quality and technical supervision departments to take appropriate actions against the non-compliant products and their manufacturers in accordance with existing laws and regulations. This step aimed to ensure consumer safety and maintain market order.
