コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies to various types of urinals (excluding waterless urinals) installed on cold water supply pipelines in building facilities, operating under a static water pressure not exceeding 0.6 MPa. It is mandatory for evaluating the water efficiency of these products. It references terms defined in GB/T 9195.

技術要求

The standard classifies water efficiency grades for urinals into three levels, with Grade 1 being the most efficient and Grade 3 being the minimum allowable value. Manufacturers must ensure their products meet at least Grade 3 requirements to enter the market. It also specifies the water-saving evaluating value as Grade 2. Additionally, the standard outlines functional requirements including washing function, sewage replacement function, and water seal depth for urinals with an integral trap. Compliance with these functional metrics is essential for overall certification.

試験方法

Testing procedures are detailed in the normative appendix and include the average water consumption test conducted under specific static pressures (0.17 MPa and 0.55 MPa). It also covers the washing function test using ink lines, the sewage replacement test using methylene blue solution, and various trap tests such as water seal depth and recovery. These tests must be performed using a standardized supply system.

よくある質問

What products are regulated under GB 28377-2019?

It regulates various types of urinals installed in building facilities, excluding waterless urinals, operating under a static pressure of 0.6 MPa or less.

What is the minimum allowable water efficiency grade?

The minimum allowable value corresponds to Grade 3. Products must meet this threshold to be compliant. The water-saving evaluating value is Grade 2.
