Full title and description

Road vehicles — Aerosol separator performance test for internal combustion engines — Part 1: General. ISO 17536-1:2015 establishes general conditions, definitions and the fundamental principles used when carrying out blowby oil aerosol separator performance tests using laboratory or engine methods and using gravimetric or fractional test techniques.

Abstract

ISO 17536-1:2015 specifies the general conditions, defines terms and sets out the basic principles for testing the performance of aerosol (oil) separators used to remove blowby oil aerosol in internal combustion engines. The standard supports both laboratory and engine test methods and allows results to be obtained by gravimetric or fractional efficiency techniques.

Scope

ISO 17536-1:2015 defines the scope and general principles for performance testing of aerosol separators (oil separators) used to capture blowby oil aerosols in internal combustion engine crankcase ventilation paths. It sets out terminology, general test conditions, and the framework that Parts 2–5 (laboratory and engine test methods, gravimetric and fractional efficiency procedures) use in order to produce comparable and repeatable performance data.

Key topics and requirements

• Definitions and terminology for blowby oil aerosols and separator performance metrics (e.g., collection efficiency, fractional efficiency).
• General test conditions and environmental/test rig parameters required for both laboratory and engine testing.
• Permitted measurement techniques: gravimetric mass collection and fractional (particle-size dependent) efficiency methods.
• Requirements for sample handling, conditioning, and reporting of test results to ensure repeatability and comparability.
• Framework for conducting both bench (laboratory) and engine-based tests; references to subsequent parts that give detailed procedures.

These topics reflect the standard's role as the general (Part 1) specification that other Parts (2–5) expand into specific test procedures.

Typical use and users

Typical users are automotive manufacturers (OEMs), component suppliers (separator designers and manufacturers), independent test laboratories, and R&D groups working on crankcase ventilation systems. The standard is used to specify test conditions in procurement, to qualify separator designs, and to generate performance data for design and regulatory purposes.

Related standards

ISO 17536 is a multipart series. Relevant related documents include: ISO/TS 17536-2 (laboratory test method), ISO/TS 17536-3 (engine gravimetric test method), ISO 17536-4 (laboratory fractional efficiency test method) and ISO/TS 17536-5 (engine fractional efficiency and upstream distribution sampling method). Part 1 provides the general principles referenced by these parts and technical specifications.

FAQ

Q: What is this standard?

A: ISO 17536-1:2015 is the Part 1 (General) of the ISO 17536 series that defines general conditions, terminology and the basic principles for testing aerosol (oil) separators used with internal combustion engine blowby.

Q: What does it cover?

A: It covers general requirements — definitions, test conditions, measurement approaches and reporting — that underpin laboratory and engine-based performance tests for oil aerosol separators, leaving detailed procedures to the subsequent parts of the series.

Q: Who typically uses it?

A: Automotive OEMs, separator and component suppliers, independent testing laboratories, and research and development teams concerned with crankcase ventilation and separator performance.

Q: Is it current or superseded?

A: The standard was published 19 November 2015 and remains an active international standard; it was amended by ISO 17536-1:2015/Amd 1 (published May 2021). ISO has also issued work in progress (a DIS stage) to revise Part 1, so users should check for any newer revisions or publication actions when specifying the latest normative text.

Q: Is it part of a series?

A: Yes — ISO 17536 is multipart. Part 1 is the general requirements; other parts (Parts 2–5 and associated technical specifications) define laboratory and engine test methods and both gravimetric and fractional efficiency procedures.

Q: What are the key keywords?

A: Aerosol separator, oil separator, blowby, crankcase ventilation, fractional efficiency, gravimetric, engine test, laboratory test, separator performance.
