Full title and description

St ISO 12584-2013 — ISO 12584:2013: Aerospace — Hydraulic fluid components — Expression of particulate contamination levels. This international standard defines how to report and communicate particulate contamination (cleanliness) levels for components used in aerospace hydraulic/fluid systems, including a coding system for shortened and complete cleanliness data reporting.

Abstract

ISO 12584:2013 specifies a method and coding system for expressing particulate contamination levels of hydraulic fluid components in aerospace applications. It provides a standardized way to report measurement results and to specify cleanliness requirements so that suppliers, manufacturers, testers and end users can exchange contamination information unambiguously.

General information

• Status: Published (confirmed current following ISO periodic review).
• Publication date: November 2013 (Edition 1, 2013).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 49.080 (Aerospace engineering systems and components).
• Edition / version: Edition 1 (2013).
• Number of pages: 10 (ISO published text); national adoptions/publications may show different page counts.

Scope

Defines the method of reporting and communicating contamination (cleanliness) levels of components used in aerospace fluid systems. Establishes a coding system that permits cleanliness results to be recorded and transmitted both in abbreviated (short) and in extended (complete) forms for use in reporting measurement outcomes and specifying component cleanliness requirements.

Key topics and requirements

• Standardized expression of particulate contamination levels for hydraulic fluid components.
• Definition of a coding system for reporting cleanliness data (short and complete forms).
• Guidance for communicating measurement results between laboratories, suppliers and users.
• Application specifically targeted at aerospace hydraulic/fluid-system components and their cleanliness specifications.

Typical use and users

Used by aerospace component manufacturers, hydraulic-system designers, maintenance and inspection teams, quality assurance and metrology laboratories, procurement/specification engineers, and suppliers who must specify, measure or verify particulate cleanliness of hydraulic components and assemblies.

Related standards

Closely related standards address particle-count coding and contamination measurement methods for hydraulic fluids and components — for example ISO 4406 (method for coding particulate contamination levels in hydraulic fluids) and ISO 4405 (gravimetric determination of particulate contamination). Other relevant technical reports and standards in hydraulic contamination and component cleanliness are maintained by ISO technical committees active in fluid power and aerospace (see ISO/TC 20/SC 10 and ISO/TC 131/SC 6 for related items and guidance).
