New amendment to gasfitting standard AS/NZS 5601 Part 1
The new Amendment 3 to AS/NZS 5601.1: 2013 General Gas Installations, published on 24 April 2020, includes a new baseline conditions test, which must be performed as part of the spillage test requirements under Appendix R – Spillage Test for Flued Appliances.
Open-flued gas appliances can be affected by external temperature conditions or wind gusts, which can impact the smoke pattern seen during a smoke test.
By establishing a baseline smoke pattern for each appliance, gasfitters can determine whether the smoke pattern observed during a negative pressure test is a result of external weather conditions or the operation of exhaust fans and kitchen rangehoods.
All gasfitters working on gas appliances must familiarise themselves with the new, updated test procedure.
