42、 systems that use sensors, controls and mechanisms for the prevention of backow for sanitary drainage and storm systems and species minimum requirements for materials, mechanical, electrical, performance tests and markings. 1.2 The purpose of this Standard is to enhance health and safety by: a) Spec
43、ifying acceptable criteria for sensor operated backwater prevention systems; b) Serving as a guide for producers, distributors, architects, engineers, contractors, installers, inspectors and users; and c) Promoting understanding regarding materials and manufacturing of sensor operated backwater prev
44、ention systems. 2 Units of Measurement 2.1 Only metric SI units of measurement are used in this Standard. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The rst stated value is the requirement. 3 Reference Publications 3.1 See An
45、nex A for a list of publications referenced in this standard. Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. When the latest edition of a standard is not applicable, the appr
46、opriate edition is indicated accordingly in Annex A. 4 Glossary 4.1 SEALING ELEMENT A pneumatic or mechanical component in a backwater prevention system that when deployed or activated, prevents the reverse ow of storm or sanitary drainage.
