6 CLAUSE 6.4 Inoculum Growth of Aquatic Micro-organisms The non-metallic components were immersed at the in-use exposure. The surface area of each component was in the range 1000 mm2 per Litre to mm2 per Litre. Extracts were prepared using 250 ml volumes of test water. Growth of Aquatic Micro-organisms (Appendix E) The volume of the inoculum was 50 ml Not applied. Mean Dissolved Oxygen Control 7.5 Mean Dissolved Oxygen Difference Positive Reference 5.8 Negative Reference 0.1 Test 0.20 The product passed the requirements of clause 6.4 when tested at the in-use exposure. 1.

7 CLAUSE 6.5 Cytotoxic Activity of Water Extract a total volume of 500 ml (50 hardness water). Cytotoxic Activity of Water Extract (Appendix F) Non cytotoxic. The product passed the requirements of clause 6.5 when tested at the in-the-product exposure with a scaling factor of 1. The test extracts and blank extracts were used to prepare nutrient growth medium and subsequently used to grow a cell line (ATCC Number CCL 81) in the analysis. In addition zinc sulphate (0.4 mmol) was used for the positive control in the analysis. Stella Fanok Page 6 of 8

8 CLAUSE 6.6 Bacteria Strain Mutagenic Activity of Water Extract a total volume of 500 ml (50 hardness water). Mutagenic Activity of Water Extract (Appendix G) Number of Revertants per Plate Salmonella typhimurium TA98 S9 - Blank Sample Extract Positive Controls 34, 51, 47 37, 33, , 2246, ± ± ± NPD (20mg) + 45, 47, ± , 30, ± , 2017, ± AF (20mg) Salmonella typhimurium TA , 377, ± , 367, ± , 982, ± 20.3 Azide (1.0mg) + 292, 292, ± , 280, ± , 2085, ± AF (20mg) Salmonella typhimurium TA , 698, ± , 776, ± , 2000, ± 72.8 Mitomycin C(10mg) + 712, 753, ± , 755, ± Comments S9 was used as a metabolic activator. NPD (4-nitro-o-phenylenediamine), Azide, and Mitomycin C are specific positive controls for strains TA98, TA100 and TA102 respectively while 2 - AF (2-aminofluorene) when used in conjunction with S9 is a positive control for both TA98 and TA100 The product passed the requirements of clause 6.6 when tested at the in-the-product exposure with a scaling factor of 1.

9 CLAUSE 6.7 Method of Analysis Extraction of Metals a total volume of 500 ml (50 hardness water). Extraction of Metals (Appendix H) All methods used to determine concentrations of metals are based on those described in the 21st edition of Standard Methods for the Examination of Water and Wastewater published by the APHA, AWWA and WEF (2005). The methods have been adapted for the instrumentation in use at the Australian Water Quality Centre. Concentration of the metals described in Table 2 of the AS/NZS 4020:2005 are determined as follows: Antimony, Arsenic, Barium, Cadmium, Chromium, Copper, Lead, Mercury, Molybdenum, Nickel, Selenium and Silver by Inductively Coupled Plasma Mass Spectrometry. Final Extract Antimony Arsenic Barium Cadmium Chromium Copper Lead Mercury Molybdenum Nickel Selenium Silver Limit of Reporting Blank < < < < < Test 1 Test 2 < < < < < < < < Max Allowed The product passed the requirements of clause 6.7 when tested at the in-the-product exposure with a scaling factor of 1.
