This document specifies the requirements and inspection indicators for the sanitary safety evaluation of distribution equipment, protective materials, and treatment materials in drinking water system. It also describes the inspection methods. This document applies to the sanitary and safety evaluation of drinking water distribution equipment, protective materials, and treatment materials.2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB 5749, Standards for drinking water quality GB/T 5750 (all parts), Standard examination methods for drinking water GB/T 6682, Water for analytical laboratory use -- Specification and test methods GB/T 17218-2025, Hygienic safety evaluation of chemicals used in drinking water treatment GB 31604.31, National food safety standard - Food contact materials and products -- Determination of residual and migration of vinyl chloride, 1,1-dichloroethylene and 1,1-dichloroethane3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. 3.1 distribution equipment Pipes, fittings, water storage containers, pressure-free water supply equipment, water dispensers, sealing and waterproofing materials, and mechanical parts that come into contact with drinking water during the process of delivering drinking water to users. 3.2 protective materials Materials such as coatings and linings used to protect drinking water pipeline systems or water storage containers that come into contact with drinking water. 3.3 treatment materials Water-insoluble materials used to purify soluble, suspended, or colloid substances in drinking water through water treatment methods such as adsorption, filtration, ion exchange, aeration, oxidation, and reduction.4 Hygiene requirements
4.1 Distribution equipment, protective materials, and treatment materials shall not pollute the water quality. The quality of the effluent shall meet the requirements of GB 5749. 4.2 Distribution equipment, protective materials, and treatment materials shall be subjected to immersion tests according to the provisions of Annex A, Annex B, and Annex C, respectively. The immersion test shall simultaneously test both the immersion water and the blank control water. The hygiene requirements for the test indicators shall comply with the provisions of Tables 1 and 2.The evaluation of protective materials shall use the test results of immersion water over 30 d. Two samples of the same product shall be tested simultaneously. The test results of both samples shall meet the corresponding hygiene requirements. 4.3 The following toxicological tests shall be added to the 30-d immersion water test of protective materials. The test results shall meet the following requirements. a) Acute oral toxicity test. the median lethal dose (LD50) shall not be less than 10 g/kg body weight; b) Genetic toxicology test. both the bacterial reverse mutation test and the chromosome aberration test shall be negative.5 Inspection indicators and inspection methods
5.1 The immersion tests for all products shall verify the standard parameters listed in Table 1.Extended parameters for immersion tests of distribution equipment, protective materials, and treatment materials shall be determined according to the product category and material, as specified in Tables 3, 4, and 5 respectively. The quantity and specifications of the products shall be determined based on the water sample volume required by the test method. 5.2 The immersion test of the protective material is conducted for a total of 30 d. The test indicators for immersion tests at 1 d and 30 d are those specified in 5.1.The test indicators for immersion tests at 3 d, 5 d, 10 d, and 20 d are the routine indicators listed in Table 1 and the indicators that do not meet the requirements of 4.2 in the 1-d immersion test. 5.3 The test method for vinyl chloride is GB 31604.31.The test methods for other indicators are GB/T 5750 (all parts), and the toxicological tests are the corresponding methods specified in Annex B of GB/T 17218-2025.Annex A
(informative) Immersion methods for distribution equipment A.1 Sample pretreatment A.1.1 Specimen preparation. the specimen preparation method for adhesive sealing and waterproofing materials is to apply the adhesive to a 10 cm × 10 cm double-sided frosted glass slide. Before application, the glass slide shall be washed and dried, and after application, it shall be allowed to dry naturally. A.1.2 Rinsing requirements. clean the product or specimen thoroughly according to the cleaning method provided in the product instructions. If the instructions do not specify a cleaning method, first clean the product or specimen with tap water, then rinse continuously for 30 min. Then rinse 3 times with pure water. Immediately immerse in prepared water. A.2 Immersion test A.2.1 Water preparation A.2.1.1 Reagents A.2.1.1.1 Unless otherwise stated, all reagents used in this method are analytically pure, and the experimental water is Grade II water as specified in GB/T 6682. A.2.1.1.2 Chlorine stock solution [c = 0.025 mol/L]. Take 7.3 mL of sodium hypochlorite (5% NaClO). Dilute with pure water to 200 mL. Store in a tightly sealed brown bottle. Store in a cool, dark place. Measure its concentration (ρ) before use. Calculate the volume of chlorine stock solution to be added to the prepared water to obtain 2.0 mg/L free chlorine using formula (A.1). ρ - Concentration of chlorine stock solution, in milligrams per milliliter (mg/mL). A.2.1.1.3 Calcium hardness stock solution [c = 0.04 mol/L]. Weigh 4.44 g of anhydrous calcium chloride (CaCl2) and dissolve it in pure water. Dilute with pure water to 1 L. Mix thoroughly. Prepare fresh solution weekly. A.2.1.1.4 Sodium bicarbonate buffer [c = 0.04 mol/L]. Weigh 3.36 g of anhydrous sodium bicarbonate (NaHCO3) and dissolve it in pure water. Dilute with pure water to 1 L. Mix thoroughly. Prepare fresh weekly. A.2.1.1.5 Hydrochloric acid [c = 0.1 mol/L]. Take 0.83 mL of hydrochloric acid (ρ20 = 1.19 g/mL). Dissolve it in pure water. Dilute to 100 mL. A.2.1.2 Preparation The required water concentrations are. pH is 8.0 ± 0.2, hardness is 100 mg/L, and free chlorine is 2.0 mg/L. The preparation method is as follows. Take 25 mL of sodium bicarbonate buffer, 25 mL of calcium hardness stock solution, and the required volume of chlorine stock solution. Dilute to 1 L with pure water. Adjust the pH to the required level with hydrochloric acid. Prepare the required volume of water for the actual test according to this ratio. A.2.2 Immersion requirements A.2.2.1 The ratio of the surface area of water pipes, fittings, water storage containers, negative pressure water supply equipment, water dispensers, and mechanical parts in contact with the prepared water to the volume of the prepared water shall, in principle, not be less than the maximum ratio under actual use conditions. For a series of products, the smallest product in the same series shall be used for immersion and testing. When the volume of the water storage container or the cavity/box of the negative pressure water supply equipment is too large, it can be appropriately reduced before immersion. All immersion water shall be collected after immersion. The immersion water shall be diluted with blank control water to ensure that the ratio of the surface area of the water storage container or the cavity/box of the negative pressure water supply equipment in contact with the prepared water to the volume of the diluted immersion water is 50 cm²/L. The diluted immersion water shall be tested. For fittings and mechanical parts such as faucets, valves, water pumps, and water meters with a volume less than 1 L, a single product shall be immersed, diluted with blank control water to 1 L, and then tested. A.2.2.2 The sealing and waterproofing materials shall be immersed and tested under the condition that the surface area in contact with the prepared water is 15 cm2/L as the volume ratio of the prepared water. A.2.3 Immersion ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
