International Accreditation Japan (IAJapan)

About JNLA


JNLA stands for the Japan National Laboratory Accreditation System which refers to a testing laboratory accreditation system based on the JIS Law enforced in September 1997 and October, 2004.
At the 196th ordinary session of the Diet in 2018, the Bill for the Act of Partial Revision of the Unfair Competition Prevention Act, etc. (Act No. 33 of 2018) was approved and the Act was established. In line with this, the Industrial Standardization Act was partially revised to newly entitle data and services as targets of standardization under the Japanese Industrial Standards (JIS) and to change the title of the Industrial Standardization Act from the “Kogyo Hyojyunka Ho” to the “Sangyo Hyojyunka Ho” in Japanese as well as the title of The Japanese Industrial Standards (JIS) from the “Nihon Kogyo Kikaku” to the “Nihon Sangyo Kikaku” in Japanese.


JNLA was internationally accepted to have been operated based on these standards and consequently became a signatory of APLAC (Asia Pacific Laboratory Accreditation Cooperation) /MRA (Mutual Recognition Arrangement) in October 1998, then of ILAC (International Laboratory Accreditation cooperation) / MRA (Mutual Recognition Arrangement) in November 2000 and later as IAJapan which was formed from a restructure of JCSS and JNLA on 1 April 2002. This was a further step forwards to an international One-Stop-Testing which means results tested once are valid worldwide. Under the JNLA program, an accredited testing laboratory can issue a test certificate with a special JNLA symbol described in above figure.


A assessment for accreditation examines a testing
laboratory whether its management system, competence
testing facility and equipment are appropriate for specific
JIS test according to the results of document review, on-site
assessment and proficiency testing. An accredited testing
laboratory shall accept the follow-up surveillances to confirm its continuous competence for testing.

On 1 January 2019, the Asia Pacific Accreditation Cooperation (APAC) was established by the amalgamation of two former regional accreditation cooperations – the Asia Pacific Laboratory Accreditation Cooperation (APLAC) and the Pacific Accreditation Cooperation (PAC). IAJapan which operates JNLA is a signatory of ILAC MRA and APAC MRA.
