便携式防回流组件现场测试套件（BFTK）用于测试防回流组件的性能。ASSE 1064涵盖了BFTKs的性能要求和精度。本标准仅限于模拟刻度盘型和数字仪表。双联仪表不属于本标准的一部分。BFTK的设计应使其便于携带。便携式BFTK的设计应能根据预先制定的测试程序指示防回流组件的操作。BFTK应包括测试所需的所有仪表、软管、阀门和配件。

Portable backflow prevention assembly field test kits (BFTK) are used in testing the performance of backflow prevention assemblies. ASSE 1064 covers the performance requirements and accuracy of BFTKs. This standard is confined to analog dial type and digital instrumentation. Duplex gauges are not a part of this standard. BFTKs shall be of a design making them portable. Portable BFTKs shall be designed to indicate the operation of a backflow prevention assembly to pre-established testing procedures. The BFTK shall include all gauges, hoses, valves and fittings as required for testing purposes.
