ISO 12500-2:2007 specifies the test layout and test procedures required for testing hydrocarbon vapour adsorbent filters used in compressed air systems to determine their effectiveness in removing hydrocarbon vapours. The performance characteristics to be identified are the adsorptive capacity and the pressure drop. ISO 12500-2:2007 defines one method of presenting filter performance as hydrocarbon-vapour capacity, expressed in milligrams, from results obtained under test conditions.

Overview

ISO 12500-2:2007 - Filters for compressed air - Test methods - Part 2: Oil vapours - specifies a standardized test layout and procedures for evaluating hydrocarbon vapour adsorbent filters (for example, activated carbon) used in compressed air systems. The standard defines how to determine key performance metrics - primarily adsorptive capacity (mass of hydrocarbon vapour a filter adsorbs) and pressure drop - and presents a method for reporting hydrocarbon-vapour capacity in milligrams under defined test conditions.

Key topics and technical requirements

Test scope and layout: Detailed schematic test arrangement (evaporator, hydrocarbon vapour detector, flow controls, bypass, data recorder) and material/assembly recommendations (e.g., stainless-steel piping, grounding).

Test agent: Liquid n‑hexane (≥98% purity) is prescribed to simulate compressor oil vapour challenge.

Reference conditions: Standard reference gas conditions (air temperature ~20 °C, absolute pressure ~100 kPa) and use of equivalent rated flow at 700 kPa [7 bar(e)] for velocity equivalence.

Breakthrough definition: Downstream concentration reaching 1 mg/kg constitutes breakthrough; time to breakthrough is recorded.

Measurements:

Upstream and downstream hydrocarbon concentration (e.g., flame-ionization detector or infrared analyser per ISO 8573-6).
Differential pressure (pressure drop) across the filter under test.
At least three samples per model; results averaged.

Adsorbed mass calculation: The standard provides the calculation method to convert concentration, flow and time-to-breakthrough into milligrams of adsorbed hydrocarbon.

Uncertainty & reporting: Guidance on measurement uncertainty and required test-report data (statement of conformity, model numbers, average adsorbed mass, pressure drop). Annexes include equipment description and a sample report form.

Applications and who uses this standard

ISO 12500-2:2007 is used by:

Filter manufacturers - to rate and publish hydrocarbon-vapour capacities and pressure-drop data.

Compressed air system designers and integrators - for filter selection and sizing to meet purity targets.

Test laboratories and certification bodies - to perform reproducible performance tests and validate manufacturer claims.

Maintenance and facilities managers - to estimate service life and replacement intervals for activated carbon or oil‑vapour filters.

Specifiers and procurement teams - to write technical specifications requiring standardized test-based performance.

Practical applications include selecting oil‑vapour adsorbent filters to protect instrumentation, pneumatic controls, painting processes and food/pharma compressed-air systems where oil vapour and odour removal is critical.
