MEASUREMENT OF WATER FLOW INCLOSED CONDUITS - METERS FOR COLD POTABLE WATER – PART 3: TEST METHODS AND EQUIPMENT (ISO 4064-3:1999, IDT)
This Malaysian Standard is applicable to meters for cold potable water, as defined in clause 1 of ISO 4064-1. It specifies the test methods and means to be employed in determining the principal characteristics of water meters.
NOTE 1 ISO 4064-1 deals with terminology, technical and dimensional characteristics, metrological characteristics and pressure loss. ISO 4064-2 deals with installation requirements.
NOTE 2 Legal requirements take precedence over the specifications of this part of ISO 4064. In particular, it should be noted that in countries where legal requirements specify that the tests are to be carried out in accordance with the rules of the International Organization of Legal Metrology (OIML), for example for pattern approval and initial verification of water meters, OIML recommendation R 49 should be followed.
