Practical Performance Accreditation System JLMA Testing Laboratory
The Japan Lock Manufacturers Association (JLMA), of which we are a member, strives to operate a “Practical Performance Certification System” that enables the standardization of product quality and appropriate product selection for the conditions of use.
In 2014, we established a testing laboratory to constantly monitor, supervise, and evaluate whether the performance of products manufactured and sold comply with JIS standards and meet quality grades, and obtained approval as a “Product Performance Testing Center” after a rigorous examination. In operating the Product Performance Testing Center, we have also strengthened the management of facilities and the training of test personnel, and are contributing to the stable supply of even higher quality products based on safety and security.
