ACCREDITATIONS/APPROVALS
KMTL’s management method is based on globally recognized ISO 9001 and ISO/IEC 17025 to meet the requirements of the nuclear industry, aircraft industry, and a wide variety of fields. Also, we are the first material testing laboratory in Japan to be accredited to Nadcap (a special process accreditation program in the aerospace industry).,
We believe the quality management system is of utmost importance in meeting the needs of our customers. The quality assurance is at the core of our services– testing, machining, designing and analysis–to continuously meet the expectations of customers worldwide.
In addition to ISO 9001:2000 (Quality Management System)confirming our, credibility as a laboratory, we obtained certification to JIS Q 9100,which has higher trust from the aerospace industry,in 2005.
JIS Q 9100 was established in Japan as the quality management system standard for the aerospace and defense industry.Equivalent standards are AS 9100 in North America and EN 9100 in Europe. JIS Q 9100 includes requirements specific to the aerospace and defense industry in addition to requirements of ISO 9001.

ISO/IEC 17025 is an international standard specifying, general requirements for the competence of testing and calibration laboratories. This accreditation, officially ensures that a laboratory has the competence to carry out specific tests and/or calibrations. Test certificates issued by a laboratory accredited by based on the accreditation from JAB are accepted worldwide through mutual recognition agreements.
KMTL was first accredited to this standard in 1998. The present accreditation scope is as shown below.

JIS Q 17043 is a Japan Industrial Standard created without changing the technical content and structure of ISO / IEC 17043. Accreditation bodies grant accreditation to this standard to proficiency testing providers that satisfy the requirements.
The proficiency test provider accreditation is one of the means to determine the competence of a proficiency test provider providing specific types of proficiency testing. Customers can use this official approval as a convenient means to identify and select a reliable proficiency testing provider that satisfies their needs.
KMTL Edge Tech Co., Ltd, a group company of Kobe Material Testing Laboratory Co., Ltd. has been accredited to JIS Q 17043 since February, 2016. The accreditation scope was expanded on February 26, 2018,for the second time to perform proficiency testing for the following.

Nadcap is a global cooperative accreditation program for special processes* for aerospace engineering, defense and related industries administrated by the Performance Review Institute (PRI). Nadcap’s membership consists of “Prime Contractors” including Boeing, Airbus, GE, and Rolls Royce. Nadcap accreditation is mandatory for their suppliers.
* A special processes refers to the process where the product as a result of the process cannot be readily or economically inspected.
