ISO/DIS 23632 Industrial valves - Design Validation - testing of valves - Draft for public comment
Why is it important?: The purpose of this type test is to validate the seat performance within manufacturer given pressure/temperature rating, provided by the manufacturer’s technical documentation of the product. This validation testing verifies torque requirements and MAST, as given in the manufacturer technical documentation. This validation test validates the durability of seat performance and operating torque through mechanical and thermal cycles. Type testing is the most reliable method to validate a product, covering many aspects, such as its design, material selection and manufacturing processes. It will also serve as a guide for valve selection, allowing customers to compare different valve types, designs and brands. Having an international standard will reduce manufacturer's cost by decreasing the number of design validations and end-user total cost-of-ownership by eliminating unintentional design flaws and planned obsolescence. The work in the ISO committee will complement the work on prEN17070 in CEN TC69/WG1, which is intended to established performance levels for different valve types for different applications
Supersedes: This is the first draft of a new international standard.
