Where rainwater goods and accessories, manufactured from more than one material, are components of a system, then contact between such components shall comply with ASINZS 3500.3, AS/NZS 3500.5 or NCC, Volume Two.
NOTE: Materials sclectcd for rainwater goods should be compatible with those of the upstream roof co cring and rainwater goods (see AS/NZS 3500.3 or NCC, Volume Two).
Fasteners, including retained mandrels, shall be durable, corrosion-resistant and compatible with any other material they may he in contact with or receive drainage from.
NOTE: See also AS/NZS 3500.3. AS/NZS 3500.5 or NCC. 1WA Volume Two.
2.2 ALUMINIUM ALLOYS
2.2.1 (;encral
Rainwater goods of aluminium alloy may be plain, embossed or clad with an aluminium/zinc alloy, prepainted or anodized.
2.2.2 Rainwater goods
Aluminium alloys for the manufacture of rainwater goods shall he of the 1000. 3000. 5000 or 6000 series complying with AS/NZS 1734, AS/NZS 1866 or AS/NZS 1867, or 400 series complying with AS 1874, as appropriate. The copper content of aluminium alloys shall not exceed 0.25%. Prepainted materials shall also comply with AS/NZS 2728.
2.2.3 Accessories
Aluminium alloys for the manufacture of accessories shall comply with Clause 2.2.2 if not used for castings, or AS 1874 if used for castings.
2.2.4 Fasteners
Materials ftr (he manufacture of fasteners for rainwater goods and accessories of aluminium alloys shall be in accordance with the following:
(a) Aluminium alloys complying with Clause 2.2.2.
(b) Stainless steel complying with AS 2837—1986 and ASTM A 167-99(2009) Grade 304. Grade 305 or Grade 3 16.
2.3 ALUMINIUM/ZINC ALLOY-COATED STEEL
2.3.1 General
Rainwater goods of aluminium/zinc alloy-coated steel may be plain or prepainted.
2.3.2 Rainwater goods
Aluminium/zinc alloy-coated steel for manufacture of rainwater goods shall comply with
AS 1397 with a minimum coating of Class AZ 150. Prepainted materials shall comply with
AS/NZS 2728.
4.1 GENERAL
One or more of the tests set out in Appendices A, B and C shall be used to demonstrate the compliance of a gutter or downpipe and support system with the appropriate provisions specified in Section 3.
4.2 APPARATUS
The apparatus for each performance test shall comply with Appendices A. B or C, whichever is applicable.
4.3 VERTICAL LOAI)
When tested in accordance with Appendix A. the test specimen of a gutter or graded downpipe and its support system shall comply with the following:
(a) The strength limit state shall sustain the test load for 5.0 +1. —O mm, irrespective of any permanent deformation.
(b) The serviceability limit state shall sustain the test load for 5.0 +1, —o mm. with a maximum deflection not greater than one hundredth of the distance between the centre-lines of adjacent supports of the support system (lu), in millimetres.
5.0 +1, —0 mm after removal of the test load, the serviceability limit state shall have—
(i) a residual deflection not greater than 0.0011.,; and
(ii) no permanent local deformation, fracture or other failure.
NOTES:
I Limits on residual deflection have been included to presere the appearance of rainwater goods and to minimize ponding. Residual deflection may be difficult, however, to determine reliably because of frictional effects and the like. Techniques performed to improve the reliability of the measurement, such as light tapping of the test specimen. are permissible provided it can he demonstrated that such techniques serve only to settle it to its rest position.
2 The location of maximum deflection may not necessarily coincide with the position of maximum deformation. Consideration should he given to the application of the concentrated load directly over a support or mid-span.
4.4 hORIZONTAL LOAfl
When tested in accordance with Appendix B, the test specimen of an eaves gutter or graded downpipe and its support system shall have—
(a) defiections not greater than given in Table 4. I; and
(b) no permanent local deformation, fracture or other failure.
