ISO 5011 vs. Legacy SAE J726 Air Cleaner Test Reference

Current ISO air-cleaner performance testing compared with a withdrawn SAE legacy reference

ENGINEERING OBJECTIVE

Interpret current ISO 5011 performance data and legacy SAE J726 documentation without treating the withdrawn SAE document as a current equivalent standard.

COMPARISON SCOPE

Covers ISO 5011 as the current engine-intake air-cleaner performance-test reference and SAE J726 only as historical context for legacy data. SAE J726_200206 was canceled on 27 June 2002. Results from different test methods or historical datasets must not be treated as directly interchangeable without validated correlation evidence.

GOVERNING STANDARDS

ISO 5011:2020ISO 5125:2020

OPTION DEFINITIONS

AISO 5011:2020

ISO 5011 defines laboratory performance testing for inlet air-cleaning equipment used with internal-combustion engines and compressors. Application decisions should use the applicable ISO test data together with equipment requirements and validated operating conditions.

ADVANTAGES

+Current governed reference for engine-intake air-cleaner performance testing in the ELIMFILTERS Knowledge Center

+Supports controlled comparison of restriction, efficiency and dust-capacity performance under its defined method

+Provides a current standards owner for new technical content and procurement interpretation

LIMITATIONS

−Laboratory results remain method- and condition-specific and do not by themselves determine field service intervals

−Performance data generated under another test method cannot be assumed equivalent without correlation evidence

TYPICAL APPLICATIONS

·Current engine-intake air-cleaner performance specifications referencing ISO 5011

·Engineering comparison of filter restriction, efficiency and capacity under a common method

·Technical review of replacement elements when comparable ISO 5011 evidence is available

BSAE J726 — withdrawn legacy reference

SAE J726 is retained here only to interpret historical air-cleaner documentation. The final J726_200206 revision was canceled on 27 June 2002; it must not be presented as a current North American equivalent to ISO 5011 or as governing evidence for new ELIMFILTERS claims.

ADVANTAGES

+Useful for identifying the test basis stated in historical equipment or filter documentation

+Helps prevent legacy results from being compared to current ISO 5011 data without recognizing the method difference

LIMITATIONS

−Canceled document; not a current ELIMFILTERS governing standard

−Historical data must retain its original test context and cannot be converted into ISO 5011 performance by assumption

−OEM or application requirements must be verified from current equipment documentation rather than inferred from the legacy reference

TYPICAL APPLICATIONS

·Interpretation of archived test reports or legacy maintenance documentation explicitly citing SAE J726

·Historical baseline review where the original test method must be preserved for traceability

ENGINEERING COMPARISON MATRIX

DIMENSION	A — ISO 5011:2020	B — SAE J726 — withdrawn legacy reference
Governance status	Current governed ISO reference	Withdrawn/canceled legacy reference
Use in new ELIMFILTERS claims	Permitted when supported by applicable test evidence	No — historical interpretation only
Cross-method equivalence	Use ISO 5011 results as ISO 5011 results	Do not infer ISO 5011 equivalence from legacy SAE J726 data
Service-interval meaning	Test data may inform application engineering; field interval remains application-specific	Legacy results do not define a current service interval

WHEN TO USE A

ISO 5011:2020

✓Current engineering specifications and technical comparisons that reference ISO 5011

✓New ELIMFILTERS technical content requiring a governed air-cleaner test-method owner

WHEN NOT TO USE

✗When the available result was generated under a different method and no validated correlation to ISO 5011 exists

WHEN TO USE B

SAE J726 — withdrawn legacy reference

✓Interpreting historical documentation that explicitly cites SAE J726

✓Tracing the origin of legacy air-cleaner performance data without converting it into a current ISO claim

WHEN NOT TO USE

✗New product qualification or current standards claims

✗Any statement describing SAE J726 as active, current or equivalent to ISO 5011

ENGINEERING IMPLICATIONS

01Always identify the test method before comparing restriction, efficiency or capacity values.

02Do not present SAE J726 as a current equivalent or alternative governing standard to ISO 5011.

03Do not use ISO 3724 as an air-filter service-interval authority; it belongs to hydraulic filter-element fatigue testing, not engine-air service life.

04Field service decisions require equipment requirements, operating conditions and validated restriction/condition evidence in addition to laboratory test data.
