This document describes two methods to measure in repeatable conditions the filtration efficiency of filter elements used in aviation and aerospace hydraulic fluid systems. It can be applied when evaluating the overall characteristics of a filter element according to ISO 14085-1, or separately. Since the filtration efficiency of a filter element can change during its service life as it is clogging, this test method specifies its continuous measurement by using on-line particle counters with continuous injection of test contaminant and recirculation of particles not retained by the test filter element until the differential pressure across the element reaches a given final or “terminal” value. This document allows the efficiency to be measured under both steady or cyclic flow conditions. It is also applicable to measuring the stabilized contamination levels that are produced by the filter element while testing with cyclic flow. This document is not applicable to qualifying a filter element under replicate conditions of service; this can only be done by a specific test protocol developed for the purpose, including actual conditions of use, e.g. the operating fluid or contamination. The test data resulting from application of this document can be used to compare the performance of aerospace hydraulic filter elements.

1.1 This document establishes the requirements for performing and documenting FAI. It is emphasized that the requirements specified in this document are complementary (not alternative) to customer and applicable statutory and regulatory requirements.
If there is a conflict between the requirements of this document, and customer or applicable statutory/regulatory requirements, the latter takes precedence.
In this document, the following verbal forms are used:
- "shall" indicates a requirement;
- "should" indicates a recommendation;
- "may" indicates a permission;
- "can" indicates a possibility or a capability.
Information marked as "NOTE" is for guidance in understanding or clarifying the associated requirement.
1.2 Purpose
The primary purpose of FAI is to verify and validate product realization processes capable of producing characteristics that meet engineering and design requirements. A FAI is not a product acceptance document. A well-planned and executed FAI by a multi-disciplinary team (e.g., members from responsible functions) provides objective evidence the manufacturer’s processes can produce compliant product, having effectively understood and incorporated the associated requirements.
NOTE While interrelated, FAI and product acceptance are separate activities. FAI focus is verification of production processes via assessment of product. FAI and supporting documentation do not provide assurance regarding conformance for product acceptance purposes; neither does the lack of a FAI necessarily imply that the product is nonconforming to engineering and design requirements.
FAI will:
- provide confidence that the product realization processes are capable of producing conforming product;
- demonstrate that the manufacturers and processors of the product have an understanding of the associated requirements;
- provide objective evidence of process capability;
- mitigate risk associated with production startup and/or process changes;
- provide assurance of product conformance at the start of production and after changes, as outlined in this document.
A FAI is intended to:
- reduce future escapes, risks, and total costs;
- help ensure product safety;
- improve quality, delivery, and customer satisfaction;
- reduce costs and production delays associated with product nonconformances;
- identify product realization processes not capable of producing conforming product, and initiate and/or validate associated corrective actions.
1.3 Application
This document applies to organizations and sub-tiers responsible for product realization processes that produce the design characteristics of the product. The organization shall flow down the requirements of this document to suppliers who produce design characteristics.
This document applies to external suppliers performing special processes. A Certificate of Conformity (CoC) provided by processors attests to satisfying the specification requirements of the applicable design authority. External suppliers providing special processes can satisfy this document’s requirements by either:
- documenting the design characteristics and associated results on a FAI;
- documenting the design characteristics and associated results on a customer-defined detailed CoC.
This document applies to assemblies, sub-assemblies, and detail parts including castings, forgings, and modifications to document catalogue or Commercial-Off-the-Shelf (COTS) items. Each of these items requires a stand-alone FAI.
Unless contractually required, this document does not apply to:

Such exchanges are used for: a) pre-flight planning for tracking or navigation support; b) scheduling tracking support; c) carrying out tracking operations (sometimes called metric predicts); d) performing orbit comparisons; e) carrying out navigation operations such as orbit propagation and orbit reconstruction; f) assessing mutual physical and electromagnetic interference among satellites orbiting the same celestial body (primarily Earth, Moon, and Mars at present); g) performing orbit conjunction (collision avoidance) studies; and h) developing and executing collaborative maneuvers to mitigate interference or enhance mutual operations. This document includes sets of requirements and criteria that the message formats have been designed to meet. For exchanges in which these requirements do not capture the needs of the participating agencies and satellite operators, another mechanism may be selected. This document is an international standard published under the auspices of CCSDS and International Standards Organization (ISO) Technical Committee 20, Subcommittee 13, developed jointly and in concert with the ISO TC20/SC14. As such, this CCSDS standard is also properly labeled as ISO 26900. The recommended Orbit Data Message format is ASCII (reference REF R_ISO_IEC_8859_1_1998 \h [4] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000001600000052005F00490053004F005F004900450043005F0038003800350039005F0031005F0031003900390038000000 ). This document describes both ‘Keyword = Value Notation’ (KVN) as well as Extensible Markup Language (XML) (reference REF R_505x0b3XMLSpecificationforNavigationDa \h[5] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000002800000052005F00350030003500780030006200330058004D004C00530070006500630069006600690063006100740069006F006E0066006F0072004E0061007600690067006100740069006F006E0044000000 ) formatted messages. Selection of KVN or XML format should be mutually agreed between message exchange partners. NOTE – As currently specified, an OPM, OMM, or OEM file is to represent orbit data for a single spacecraft, and the OCM is to represent orbit data for either a single spacecraft or single parent spacecraft of a parent/child spacecraft deployment scenario. It is possible that the architecture may support multiple spacecraft per file; this could be considered in the future.
