5、mponents iiiASSE 1060-2017ForewordThis foreword shall not be considered a part of the standard; however, it is offered to provide background information.ASSE International standards are developed in the interest of consumer safety.This standard focuses on devices that provide a range of protection f
6、or fluid conveying components that are mounted outside and above ground so that they may avoid damage from freezing, vandalism, and tampering.The title and scope of this standard was changed during the 2005 revision to, Performance Requirements for Outdoor Enclosures for Fluid Conveying Components.
7、Fluid conveying components include backflow prevention assemblies and devices, water meters, control valves, pressure reducing valves, air release valves, pumps, and other components installed outdoors and above ground that require protection from freezing, or require system security protection.Clas
8、s I and I-V enclosures provide equal or greater protection than Class II or II-V enclosures, or Class III or III-V enclosures. Class II and II-V enclosures provide an equal or greater protection than Class III or III-V enclosures. Recognition is made of the time volunteered by members of this workin
9、g group and of the support of manufacturers, who also participated in developing this standard.This standard does not imply ASSE Internationals endorsement of a product that conforms to these requirements.Compliance with this standard does not imply acceptance by any code body.It is recommended that
10、 enclosures be installed consistent with local codes by qualified and trained professionals.This standard was promulgated in accordance with procedures developed by ASSE International and approved by the American National Standards Institute (ANSI).iv Outdoor Enclosures for Fluid Conveying Component
