Full title and description

ISO 10094-2:2021 — Pneumatic fluid power — Electro-pneumatic pressure control valves — Part 2: Test methods to determine main characteristics to include in the supplier's literature. This part specifies standardized test procedures and a method for presenting test results for electro-pneumatic continuous pressure control valves, to allow consistent comparison and correct application in compressed air systems.

Abstract

This document defines test methods and presentation formats for the principal parameters that should appear in supplier literature for electro‑pneumatic continuous pressure control valves (those with an exhaust port vented to atmosphere). The tests are intended to enable comparison between valve types and to support proper application; they are not intended as production inspection tests. The document also cross‑references related test methods for non‑electrically modulated valves and for flow control valves.

Scope

This part (ISO 10094‑2:2021) specifies the test procedures and the method of presenting results for the parameters that define the main characteristics to be included in supplier literature for electro‑pneumatic continuous pressure control valves. It is limited to components with an exhaust port vented to atmosphere and is intended to standardize measurement and presentation so that different valve types can be compared. The tests described are comparative and informative, not routine production tests.

Key topics and requirements

• Standardized test methods for determining key performance parameters of electro‑pneumatic continuous pressure control valves (e.g., flow/pressure characteristics, hysteresis, dynamic response, leakage where applicable).
• Guidance on presenting test results and main characteristics in supplier literature to facilitate user comparison and correct application.
• Tests intended for components with exhaust to atmosphere; alternative or related test methods for other valve types are referenced (see related standards).
• Clarification that the specified tests are comparative (design/characteristic tests) rather than production acceptance tests.

Typical use and users

Used by valve manufacturers to certify and document main characteristics in datasheets, by independent test laboratories performing type or comparative testing, and by system designers, procurement engineers and technical authors who need standardized performance data for selection, specification and comparison of electro‑pneumatic pressure control valves.

FAQ

Q: What is this standard?

A: ISO 10094‑2:2021 is an ISO international standard specifying test methods and presentation requirements for the main characteristics of electro‑pneumatic continuous pressure control valves to be included in supplier literature.

Q: What does it cover?

A: It covers standardized procedures for measuring and reporting parameters (flow/pressure characteristics, dynamic behaviour, hysteresis and related characteristics) that define valve performance for electro‑pneumatic continuous pressure control valves with exhaust ports vented to atmosphere; it is intended to enable comparison between valve types.

Q: Who typically uses it?

A: Manufacturers, product documentation authors, test laboratories, system designers and procurement/specification engineers who need consistent, comparable performance data for electro‑pneumatic pressure control valves.

Q: Is it current or superseded?

A: ISO 10094‑2:2021 is the current published edition (edition 2, published November 2021). It replaced ISO 10094‑2:2010, which has been withdrawn.

Q: Is it part of a series?

A: Yes — ISO 10094 is a multipart series. Part 1 (ISO 10094‑1:2021) defines which main characteristics should appear in supplier literature; Part 2 (this document) defines the test methods and presentation for those characteristics. Other related ISO standards address non‑electrically modulated valves and flow control valves.

Q: What are the key keywords?

A: Electro‑pneumatic, pressure control, proportional valve, pneumatic fluid power, test methods, supplier literature, flow characteristics, hysteresis, response time, ISO 10094.
