Interim progress reporting is made available during this period, with estimated completion dates on the various tests. Products not requiring Growth of Aquatic Micro-organisms test: 6 weeks. Consult the laboratory prior to sending samples for testing.ДЇull AS/NZS 4020 testing period: 12 weeks

The number of samples required will depend on product type, end-usage and tests required. Collaboration with the certifying body is essential to ensure acceptance of the model or size selected to cover the entire range.Д«ackground information on total surface area of each wetted part and/or estimated percentage wetted is essential. worst case scenario, is required for testing. Where a range of products using the same wetted materials and processes is produced, the one with the highest surface area-to-volume ratio in the product range, i.e. Products are required to comply with all tests relevant for that product type, and the results provide guidelines for, water supply quality at consumersвЂ™ taps, with respect to general health requirements. The final extract is then analysed in accordance with the test requirements for each test. The product is immersed in, or exposed to, test water in accordance with extraction procedures as outlined for each of the tests for Taste, Appearance, Growth of Aquatic Micro-organisms, Cytotoxicity, Mutagenicity, and Extraction of Metals, including specific procedures for High Temperature tests for End-of-Line Fittings, and Water - Heating systems, as well as for Simulated samples.ДЄ scaling factor (field exposure to test exposure) can be applied to compensate for a greater surface area-to-volume ratio used for test extractions, when compared to the worst case scenario in end-use.Д®xtraction is allowed to proceed for the time given in the relevant test. The test reports for the AS/NZS 4020 test is valid for 5 years. The hot water tests apply where water has the potential for human consumption, food preparation, utensil washing and oral hygiene. It is based on water quality data collected throughout the country together with a range of geographical data sets for available background information. It is applicable to metallic and non-metallic products such as pipes, taps, fittings, components, hot water units and materials used in coating, protection, lining, jointing, sealing and lubrication applications in the water supply and plumbing industry. WaterMarque is a menu driven set of tools developed using GIS technology for the assessment, query, display and reporting of water quality information. It is a requirement in the application for WaterMarkв„ў certification.В Testing focuses on wetted partsВ only.

AS/NZS 4020 prescribes tests for analysing the suitability of products for use in contact with drinking water, with regard to their effect on the quality of the water.
