QUALITY

 By using management methods based on ISO 9001 and ISO/IEC 17025 standards, KMTL responds to the requirements of a wide variety of fields including the nuclear and aircraft industries.

 We are accredited to Nadcap (a special process accreditation program in the aerospace industry) as the first Nadcap-accredited material testing laboratory in Japan and the quality management system is of the utmost importance for us to satisfy customer needs.

 We will continuously meet the expectations of customers worldwide by providing our testing, machining, designing and analysis services based on our quality assurance.








JIS Q 9001 and JIS Q 9100

 In addition to ISO 9001:2000 (Quality Management System), which gives us high credibility as a laboratory, we obtained certification to JIS Q 9100 for higher trust from the aerospace industry.

 JIS Q 9100 was established in Japan as the quality management system standard for the aerospace industry and is applicable worldwide like AS 9100 and EN 9100 and is technically equivalent to both standards of AS and EN.

JIS Q 17025(ISO/IEC 17025)【Mechanical Testing, Chemical Testing】

 ISO/IEC 17025:2005 is an international standard, which specifies general requirements for the competence of testing and calibration laboratories. This accreditation, officially ensuring that a laboratory has the competence to carry out specific tests and/or calibrations, provide customers with a useful means to select reliable testing and calibration to meet their needs. Test certificates based on the accreditation from JAB are recognized worldwide through mutual recognition agreements.

 KMTL was first accredited to this standard in 1998. The present accreditation scope is as shown below.

JIS Q 17043:2011(ISO/IEC 17043:2010)
【Mechanical testing; Chemical testing】

  JIS Q 17043 is a Japan Industrial Standard created without changing the technical content and structure of ISO / IEC 17043. Accreditations to this standard are given by accreditation bodies 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 that provides specific types of proficiency testing. This official approval provides customers with a convenient means of identifying and selecting reliable proficiency testing providers that satisfy the customer needs.

  KMTL Edge Tech Co., Ltd, a subsidiary of Kobe Material Testing Laboratory Co., Ltd. has been accredited to JIS Q 17043 since February, 2016. On February 26, 2018, it expanded the accreditation scope for the second time to perform proficiency testing for the following.
