This Appendix sets out the means by which compliance with this Standard has to be demonstrated by a manufacturer for product certification.
Products covered by this Standard arc required to he certified under the National Certification Scheme.
A2 PRODUCT CERTIFICATION
The purpose of product certification is to provide independent assurance of the claim by the manufacturer that products comply with the stated Standard.
The certification scheme shall meet the criteria described in HB l.2S in that, as well as full type testing from independently sampled production and subsequent verification of conformance, it requires the manufacturer to maintain effective quality planning to control Production.
The certification scheme serves to indicate that the products consistently conform to the requirements of the Standard.
Product certification shall be conducted by an accredited certification body.
The frequency of the sampling and testing schedule, as detailed in Tables Al and A2, shall be used by the certifying body for product compliance auditing. However, where the manufacturer can demonstrate adequate process control to the certifying body, the frequency of sampling and testing nominated in the manufacturer’s quality plan and documented procedures shall take precedence for the purpose of product certification.
A3 TESTING
A3.1 General
Table Al sets out the requirements for type testing for a manufacturer to demonstrate compliance of product(s) to this Standard for initial certification.
Table A2 is a schedule identifying those tests and minimum frequencies to be undertaken on a routine batch-by-batch or continuous basis.
A3.2 Inspection and test schedule
The licensee’s quality plan shall include an inspection and test schedule/plan that identifies the quality control tests undertaken and their frequencies. to maintain objective evidence of ongoing compliance of product manufactured to AS 4032.4. Refer to Table A2 for minimum sampling and testing frequency.
B2 INSTALLATION INSTRUCTIONS
The installation instructions shall include the following:
(a) Clear and prominent indication of the operating temperature range of the thermostatic mixing tap.
(b) Name and address of the manufacturer and the relevant agent in the country of intended sale.
(c) Full and comprehensive installation diagrams including the specification and positioning, if necessary. of non-integral line strainers, cross-flow prevention devices (non-return valves) and isolating valves, and pressure and temperature controls devices.
Strainers and cross-flow prevention devices shall be installed downstream of the isolation valves and in the order strainer then cross-flow prevention device [see
Clause 3.5(d)1.
(d) The maximum and minimum working pressure, in kPa, and details for the fitting of any necessary pressure control device where the maximum pressure could be exceeded.
(e) The maximum heated ater operating temperature, in C. and details fbr the fitting of any necessary temperature-control device where this temperature could be exceeded.
(f) The minimum heated water operating temperature, in °C. Specify any relationship between the minimum operating temperature of the heated water and the required temperature for the mixed water, to provide effective and rapid heated water shut-off of the mixed water upon sudden reduction in pressure or shut-off of the cold water supply.
(g) The minimum and maximum cold water operating temperatures, in oC Specify any relationship between the maximum operating temperature of’ the cold water and the required temperature of the mixed water.
(h) Full details of requirements for mounting and connecting the thermostatic mixing tap.
(i) The necessary requirement for the provision of access for adjustment, maintenance, repair and replacement of the thermostatic mixing tap.
