This Standard specifies requirements for the durability and safety of drain water heat recovery (DWHR) units. This Standard applies to DWHR units of any diameter and length and configuration for use with potable water, and to their components and materials supplied by the manufacturer, their...
1.1 This test method covers determination of the short-time compressibility and recovery at room temperature of sheet-gasket materials, form-in-place gaskets, and in certain cases, gaskets cut from sheets. It is not intended as a test for compressibility under prolonged stress application,...
This International Standard specifies the test apparatus, test gas mixtures, sampling procedures and analytical techniques used to determine the performance of refrigerant recovery and/or recycling equipment.
This International Standard prescribes a method of testing the ventilation and energy related performance of heat recovery ventilators (HRVs)and energy recovery ventilators (ERVs) that do not contain any supplemental heating (except for defrost), cooling, humidification or...
