BAIJIAN - Third party testing organization
This part of the scope GB/T778 specifies the test requirements for complete water meters and water meter measurement sensors (including flow or volume detection elements) as independent units、 as well as calculators (including indicating devices). This section is applicable to the type evaluation test and initial verification test of drinking cold water and hot water meters as defined in GB/T778.1. This section provides detailed test procedures、 principles、 equipment、 and methods for the type evaluation test and initial verification test of water meters. If required by national regulations、 this section also applies to auxiliary devices. The following normative references are essential for the application of this document. For dated references、 only the dated version applies to this document. For undated references、 the new version (including all modification orders) applies to this document.
