Review of Thermoplastic Valves Standards

BSI have announced a routine ‘periodic review’ of six industrial Thermoplastic valves standards:-

ISO 21787 Globe type

ISO 16135 Ball

ISO 16136 Butterfly

ISO 16137 Check

ISO 16138 Diaphragm

ISO 16139 Gates

Recommendations to confirm or withdraw the standards are possible; a recommendation to revise must be accompanied by a detailed justification.

BSI close the comments period on 15 January 2015.

If these standards are important to you, you should consider joining BSI PSE/18/3 ‘part turn valves’ which covers 5 of these standards, or PSE/18/2 for gate types.
