CDN $251.00

This publication was last reviewed and confirmed in 2025.

Industrial valves — Measurement, test and qualification procedures for fugitive emissions — Classification system and qualification procedures for type testing of stem seals for valves

Description

This document covers the type testing of valve stem seals using a test fixture that is designed and fully defined to be representative of the performance of a valve using similar geometry.

This document is applicable to stem seals for multi-turn, linear and quarter turn valves. It is intended to provide comparative type test results confirming the performance of seal manufacturers’ stem seal designs.

This document is not intended to replace type testing of complete valve assemblies or valve production testing.

Compliance with this document is not intended to be a mandatory qualification test to be completed for a stem seal design prior to testing a valve to the requirements of ISO 15848-1.

Compressible seals with and without live loading, elastomers and pressure energized seals are in the scope of this document.

Corrosion tests are not included in this document.
