This Practice Note provides guidance on the use of junction fittings installed in gravity discharge sanitary and drainage systems.

Specifies requirements for the design, installation and commissioning of a system of sutomatic smoke/heat release vents in conjunction with associated smoke reservoirs in buildings.

This Act may be cited as the Plumbing and Drainage Act 2018. (QLD legislation.)

Specifies the apparatus and test method for determining the flammability index of a material. Main changes in this edition of the Standard are the inclusion of a statistical evaluation of the test results, a change to the speed factor formula so that the flammability indices form a continuous range and a more detailed form of test report.

Sets out test procedures and criteria for the determination of fire-resistance of elements of building construction.

Sets out a test method for the determination of ignitability, heat release rates, mass loss rates, effective heat of combustion and smoke release of materials and products when exposed to controlled levels of radiant heating.

Describes a single test method for grading building materials on the basis of ignition tendency, flame spread, heat development and tendency to produce smoke.

Specifies a test method for determining the combustibility of building materials and is one of a series of test methods of evaluating the potential fire hazard of building products; the test is for building materials other than coated, faced or laminated materials which, although not completely inert, produce only a limited amount of heat and flame when exposed to temperatures of approximately 750 °C.

To inform industry and the community about the compliance requirements under the National Construction Code (NCC) 2022 for grading floors to floor wastes with showers and other wet areas of dwellings.
