Vacuum Relief Valve Standards

This part of ISO 13693 specifies the construction and performance requirement and test methods for metal-bodied chemigation valves with water at temperatures not exceeding 50 °C, which might contain fertilizers and chemicals of the types and concentration used in agriculture. The...

This test specification stipulates the requirements, test conditions and test methods for check valves which are employed in the vacuum system of motor vehicle braking systems.

This Japanese Industrial Standard specifies requirements for the vacuum bottles comprising a double-wall vacuum glass vessel (hereafter referred to as an inner bottle), and vacuum bottles comprising a double-wall vacuum stainless steel vessel (hereafter referred to as a...

This document specifies the requirements for the design, manufacture and testing of valves for a rated temperature of −40 °C and below (cryogenic service), i.e. for operation with cryogenic fluids in addition to operation at temperatures from ambient to cryogenic. It applies to all types of...

Scope of documentation Structure-related documents required for approval of independent tank types C are given in DNVGL-RU-SHIP Pt.5 Ch.7 Sec.1 Table 6. The submitted documentation should among others contain the following descriptions: - maximum allowable relief valve setting (MARVS)...

1.1 This specification establishes requirements and test methods for dimensions and tolerances of central-vacuum hose inlet valve sockets. 1.2 All notes and footnotes shall be considered as non-mandatory requirements of the specification. 1.3 This specification does not apply to inlet...

PURPOSE The purpose of the test specification is to determine a physical test method of vacuum tank applied to GMDAT-made vehicle (passenger car, multi-purpose car, truck and bus), and to specify requirements which are to be satisfied by a vacuum tank.

Vacuum technology finds itself in many areas of industry and research. These include materials handling, packaging, gas sampling, filtration, degassing of oils and metals, thin-film coating, electron microscopy, particle acceleration, and impregnation of electrical components. It is vital to...

This International Standard specifies methods for the leak testing of vacuum valves used for control of gas flow or vacuum pressure in a vacuum system. It is applicable to vacuum valves that can be closed to leak rates less than 1 × 10−5 Pa m3/s for trace...
