Introduction of GB 27898.3-2011

Fixed water supply equipment used for fire-protection - Part 3: Pressure boosting and stabilizing type water supply equipment used for fire-protection 1 Scope This part of GB 27898 specifies the terms and definitions, classification, requirements, test methods, inspection rules, signboards and operation instructions, packaging, transportation and storage of pressure boosting and stabilizing type water supply equipment used for fire-protection. This part is applicable to pressure boosting and stabilizing type water supply equipment used for fire-protection. As for pressure boosting and stabilizing type water supply equipment with similar working principle, this part may be adopted by reference. 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.
