5.1 Cooking can be one of the most polluting activities commonly and regularly occurring in residential environments. Capturing airborne cooking contaminants before they can mix with the indoor air is a critical indoor air quality control method.5.2 Range hoods are used in homes to remove cooking-generated contaminants above cooking surfaces before they mix with air in the rest of the house. This test method is used to measure the capture efficiency under specific conditions that permit comparisons and ratings of range hoods.5.3 Range hoods may be manufactured and intended to operate at different flow rates or using different inserts such as filters. This test method may be used to determine capture efficiency over the range of rated air flows and operating configurations of a range hood. The rated air flows shall be listed and shall be tested in accordance with HVI Test Procedure 916, IEC 61591, ASHRAE 51/AMCA 210, or equivalent. The maximum air flow allowed for this test method is 200 L/s.1.1 This test method measures the capture efficiency of wall-mounted domestic range hoods under controlled conditions in a test chamber.1.2 This test method applies to range hoods that exhaust air to outside and does not apply to recirculating range hoods.1.3 This test method only applies to range hood air flows up to 200 L/s and widths up to 0.91 m (36 in.).1.4 This test method is intended to quantify the capture efficiency of range hoods under controlled laboratory conditions suitable for rating.1.5 The values stated in SI units are to be regarded as standard. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first stated value is the requirement.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This guide is intended for on-site assessment of in-service operation by short term measurement of appropriate system functions under representative operating conditions.4.2 Primary application is for residential systems and medium-size multi-family units or commercial buildings. Use of back-up conventional DHW heating system is assumed to augment solar heating.4.3 This guide is intended for use by suppliers, installers, consultants and homeowners in evaluating on-site operation of an installed system. Emphasis is placed on simplified measurements that do not require special skills, intrusive instrumentation, system modification or interruption of service to the purchaser.4.4 The purpose of this guide is to verify that the system is functioning. Copies of all data and reports must be submitted by the testing group to the owner or his or her designated agent.4.5 Data and reports from these procedures and tests may be used to compare the system performance over time, but should not be used to compare different systems or installations.4.6 Test is for a newly installed system and also for periodic checking.1.1 This guide covers procedures and test methods for conducting an on-site inspection and acceptance test of an installed domestic hot water system (DHW) using flat plate, concentrating-type collectors or tank absorber systems.1.2 It is intended as a simple and economical acceptance test to be performed by the system installer or an independent tester to verify that critical components of the system are functioning and to acquire baseline data reflecting overall short term system heat output.1.3 This guide is not intended to generate accurate measurements of system performance (see ASHRAE standard 95-1981 for a laboratory test) or thermal efficiency.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
