AS/NZS 1562.3:1996 Design and installation of sheet roof and wall cladding, Part 3: Plastic
Standards Australia/Standards New Zealand
Supersedes: AS 2921-1987 Unplasticized polyvinyl chloride (UPVC) wall cladding - General installation requirements
Draft Designation: DR 94407This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee PL/22 on Plastic Building Sheets, to amalgamate and supersede AS 2424—1991 (in part) and AS 2921—1987 (in part).
It is the third part in a series of sheet roof and wall cladding Standards which, when complete, will comprise:
AS
1562 Design and installation of sheet roof and wall cladding
1562.1 Part 1: Metal
1562.2 Part 2: Fibre-reinforced cement*
AS/NZS
1562.3 Part 3: Plastic (this Standard)
Plastic roof and wall cladding materials are installed using the normal procedures for other types of building sheets but with certain modifications to fixing techniques because of the inherent properties of the material. The purpose of this Standard is to reinforce general safety rules in relation to sheet installation and to highlight the differences in fixing techniques required for plastic sheets as compared with those used for sheets of other materials.
This Standard applies to the suite of Standards on plastic roof and wall cladding materials which, when complete, will comprise:
AS/NZS
4256 Plastic roof and wall cladding materials
4256.1 Part 1: General requirements
4256.2 Part 2: Unplasticized polyvinyl chloride (uPVC) building sheets
4256.3 Part 3: Glass fibre reinforced polyester (GRP)
4256.4 Part 4: Unplasticized polyvinyl chloride (uPVC) wall cladding and boards
4256.5 Part 5: Polycarbonate
In New Zealand technical requirements for building construction are contained in New Zealand Building Code and the Building Regulations. The following Code clauses are, or may be, relevant in respect to plastic building sheets: B1 Structure, B2 Durability, C3 Spread of Fire, E2 External Moisture, E3 Internal Moisture, F2 Hazardous Buildings Materials, G7 Natural Light, H1 Energy Efficiency.
The term ‘normative’ has been used in this Standard to define the application of the appendix to which it applies. A ‘normative’ appendix is an integral part of a Standard.
Originated in Australia as part of AS 2424-1981. Previous edition AS 2424-1991. AS 2424-1991 and AS 2921-1987 revised, amalgamated and redesignated in part as AS/NZS 1562.3:1996.
This Standard sets out procedures for the design and installation of plastic roof and wall cladding materials for walls and roofs.
The Standard is primarily intended to apply to the use of plastic roof and wall cladding materials complying with the AS/NZS 4256 suite of Standards (see Preface).
NOTES:
1: The sheets do not contribute to the structural or load-bearing capacity of the structure and due allowance should be made to the surrounding structure to compensate for the opening areas. For applications where structural design requirements must be satisfied, reference should be made to the design and testing provisions of AS 1562.1 for roofing without transverse joints.
2: For use of the sheets in abnormal environmental conditions (e.g. extremes of temperature), the advice of the manufacturer should be sought.
