T/ZSHG 028-2024 Valve Actuator Performance Test Method

Scope

Scope: This document specifies the test content and methods for the performance of valve actuators. This document applies to actuators that connect to aerosol valves and activate aerosol valves. Main technical content: 5 Test Content 5.1 Performance The performance tests include the following: a) Fluidity; b) Pull-out force; c) Fitting performance; d) Ejection pattern; e) Ejection range; f) Ejection angle (applicable to spray-type valve actuators); g) Droplet size and distribution (applicable to spray-type valve actuators); h) Insert ejection test (applicable to insert-type valve actuators); i) Crack resistance test; j) High-temperature resistance test; k) Low-temperature resistance test. 5.2 Compatibility 5.3 Microbial limit 5.4 Harmful substance limit 6 Test Methods (Fluidity, Pull-out force, Fitting performance, Ejection pattern, Ejection range, Ejection angle (applicable to spray-type valve actuators), Droplet size and distribution (applicable to spray-type valve actuators), Insert ejection test (applicable to insert-type valve actuators), Crack resistance test, High-temperature resistance test, Low-temperature resistance test, Compatibility, etc.)
