The amendment follows Commerce Commission investigations which identified that some mesh marketed in New Zealand as Grade 500E ductile steel mesh was not achieving the required 10 per cent elongation when tested to the Standard.
Amendment 14 came into effect on 4 November 2016 and provides clarification on the testing methodology. It affects Acceptable Solution B1/AS1 and Verification Method B1/VM1.
The existing Amendment 13 will continue to have effect until 30 May 2017. This allows the use of mesh that has already been manufactured and meets the current requirements in Amendment 13.
Amendment 14 introduces a requirement that only accredited laboratories carry out testing of ductile steel mesh to AS/NZS 4671:2001. This requirement will take effect on 1 January 2017 to allow laboratories time to adjust their processes and gain accreditation.
