EN 17955:2024(Main)
Industrial valves - Functional safety of safety-related automated valves
SIST EN 17955:2024

This document defines the requirements for how mechanical compliant items in a final element can be evaluated according to the principles of EN 61508 to integrate them into a safety-related system. It provides a method to determine all relevant factors, associated with the product, and thereby meet the specific needs of users of the product.
The basic prerequisite for the application of this document is that the intended use is known. This document describes a system to minimize systematic faults to achieve the targeted Safety Integrity Level (SIL).
This document is applied to single compliant items (e.g. valve, actuator or mechanical portions of solenoid valves) or to assemblies of several of these compliant items and interconnecting compliant items and components (e.g. gears, adaptors, brackets, etc.). Electrical, electronic or programmable electronic components are assessed according to EN 61508.
This document does not apply to:
-   manually operated valves;
-   items in safety systems or risk-reducing devices that are not assessed and operated according to the principles of functional safety (e.g. automatic safety valves like pressure relief valves).
The methods described can also be used for other mechanical compliant items in a final element of the safety-related system if the applicability is confirmed by appropriate expert knowledge (e.g. dampers, brakes, clutches).

Thermoplastics valves - Torque - Test method (ISO 8233:2024)
SIST EN ISO 8233:2024

This document specifies a test method for the determination of the opening, closing and running torque of thermoplastics valves.
This document is applicable to all types of manually operable thermoplastics valves, with or without actuator, intended to be used for the transport of fluids.
NOTE 1        Examples of valve types tested with this method are in ISO 4437-4, ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 16486-4, ISO 21787, EN 1555-4[13] and EN 12201-4 [14].
This document does not specify the relationship between the torque and its possible increase after prolonged use of the valve under a specific working condition or wear/chemical aggression of the materials.
NOTE 2        Concerning the chemical aggression of the materials, a collection of data is reported in ISO/TR 10358 concerning the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use with repeated opening and closing operations. Further information is provided in ISO 8659.

This document specifies the requirements for the attachment of multi-turn actuators to valves.
Throughout this document, “actuator” can be understood as “actuator and/or gearbox” providing a multi-turn and/or linear output.
It specifies:
—     flange dimensions necessary for the attachment of actuators to industrial valves [see Figure 1 a)] or to intermediate supports [see Figure 1 b)];
—     those driving component dimensions of actuators which are necessary to attach them to the driven components;
—     reference values for torque and thrust for flanges having the dimensions specified in this document.

This document specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.
The attachment of part-turn actuators to control valves in accordance with the requirements of this document is subject to an agreement between the supplier and the purchaser.
This document specifies:
—     flange dimensions necessary for the attachment of part-turn actuators to industrial valves [see Figures 1 a) and 1 c)] or to intermediate supports [see Figures 1 b) and 1 d)];
—     driving component dimensions of part-turn actuators necessary to attach them to the driven components;
—     reference values for torques for interfaces and for couplings having the dimensions specified in this document.
The attachment of the intermediate support to the valve is out of the scope of this document.

SIST EN ISO 5117:2023

This document specifies the production and performance relevant test requirements for automatic steam traps used for condensate removal/recovery services for optimized utilization of energy, in refinery, power generation or other general applications where steam is used as a medium of heat transfer.
The tests can be classified as production tests and performance characteristic tests and can be conducted to ensure the correct functioning of a steam trap or to evaluate the performance of a particular design. This document specifies the tests performed relative to each one of these two categories and briefly describes the corresponding test methods.

Testing of valves - Fire type-testing requirements (ISO 10497:2022)
SIST EN ISO 10497:2023

This document specifies fire type-testing requirements and a fire type-test method for soft- and metal-seated isolation valves with one or more obturators. It is not applicable to the testing requirements for valve actuators other than manually operated gearboxes or similar mechanisms when these form part of the normal valve assembly. Other types of valve actuators (e.g. electrical, pneumatic or hydraulic) can need special protection to operate in the environment considered in this valve test, and the fire testing of such actuators is outside the scope of this document.
This document specifies the measurement and assessment criteria for:
a) through-seat leakage;
b) external leakage;
c) cavity overpressure relief of double-seated valves;
d) operability.
This document specifies the rules whereby the fire-type testing qualification for a valve can be extended to untested sizes, pressure ratings and materials of construction of the same basic design type.
Fire test reports of valves tested according to previous editions of this document are acceptable when submitted together with the full and compliant fire test report as per 6.7 of the edition under which it was tested. Any data missing as required from 6.7 within the fire test report are accepted or rejected at the purchaser’s discretion.
NOTE       For the purposes of this document, the terms “fire type-test” and “fire test” are synonymous.
