Location Test Certificate

Any location which stores 2.1.1A substances in quantities of greater than 100kg (non-permanent gases) / 100m3 (permanent gases) and stores them for periods longer than 18 hours, requires a Location Test Certificate. 

A Location Test Certificate must be issued by a Test Certifier and is usually valid for one year.  If you require a Location Test Certificate, please contact RLNZ’s Test Certifier:
