Australian Plants: Commission Compressed-Air Quality Testing

For an Australian plant, commission compressed-air quality testing by defining the point of use, contaminants, operating conditions and the evidence needed to accept a report. Choose the applicable purity requirements with the responsible quality or engineering team before comparing laboratory offers. ISO 8573-1 provides a classification framework; it does not select one universal purity requirement for every Australian plant.[1]

Separate the purity specification from the measurement method

Require the proposal to state the method and edition for each requested measurement. The ISO and BSI public catalogue descriptions establish the following scopes. BSI identifies its cited editions as identical to the corresponding ISO editions; citing them does not establish an Australian legal requirement to use a British adoption.[1][3][4] The public descriptions are not a substitute for the complete applicable standard, an authorised laboratory procedure or a site risk assessment.

• Classification: ISO 8573-1:2010 addresses compressed-air contaminants and purity classes for particles, water and oil, and identifies additional gaseous and microbiological contaminants.[1]
• Particles: ISO 8573-4:2019 describes sampling and measuring particle size and concentration, including method limitations and uncertainty. It does not segregate the measured solid and liquid particle fractions.[2]
• Liquid oil and aerosol: ISO 8573-2:2018 addresses these fractions and explicitly excludes oil-vapour measurement.[3]
• Oil vapour: ISO 8573-5:2025 addresses oil-vapour content using pressurised sampling and gas chromatography, including evaluation, uncertainty and reporting.[4]

An aerosol-only result must not be presented as proof of every oil fraction. For water, specify the required moisture measure and its pressure basis. If viable microbiological evidence is required, commission that as a separate defined measurement rather than inferring it from a particle count. Ask the laboratory to identify its applicable procedure and reporting capability for every analyte.

Define the actual assembly and operating state

The request for quotation should identify each sampling location and whether it includes the installed filter, hose, regulator and final process connection. The laboratory must explain how its sample represents that assembly and why any substitute sampling connection is suitable. Trace Analytics’ guidance discusses sampling after the point-of-use filter and identifies sampling-connection and material considerations.[6]

• Assign an unambiguous location identifier and retain the drawing or equipment reference.
• Specify the production state the result must represent, including relevant startup or changing-demand conditions.
• Require the proposed sampling pressure, flow, duration, volume and reporting reference conditions.
• Ask the sampler to define method-appropriate preparation, purge, contamination controls, transport and handling.
• Record changes to filters, hoses, sampling connections and operating conditions before comparing later results.

These are questions for the qualified sampler and laboratory. This guide does not prescribe purge times, hardware layouts, operating setpoints or a universal sampling frequency.

Distinguish filter testing from plant contamination testing

SGS filtration testing

SGS’s Australia-facing filtration page describes filter and filtration-system testing, including compressed-air applications. Its listed service contact is in Grass Lake, Michigan, United States.[5] That is not confirmation of Australian on-site sampling, a local laboratory or a contract for measuring every contaminant at a plant’s final connection. Request a named delivery location and a scope matching the intended task.

Trace Analytics

Trace Analytics publishes compressed-air sampling guidance covering particle, water and oil testing.[6] It can inform questions about a contamination-testing proposal, but the cited guidance does not establish an Australian field sampler, a locally deliverable kit, freight and holding-time arrangements, or a laboratory accreditation scope acceptable for this site. Obtain those details in writing before commissioning work.

These examples address different services. Do not treat them as two already-confirmed Australian on-site providers or compare them on a presumed identical scope. If neither offer meets the specification, use the same method-neutral request to investigate a suitable local sampler and laboratory.

Ask for accreditation evidence that matches the work

Request the current accreditation certificate and detailed scope for the named laboratory and location, covering the proposed methods. Ask the responsible quality team whether NATA or another relevant accreditation arrangement is required or acceptable for this contract. A general accreditation claim does not establish coverage of every compressed-air method or Australian sampling activity.

The quote should distinguish who takes the sample, who transports it, who analyses it, who interprets the results and who signs the report. Require the proposal to explain any subcontracting and the limitations attached to sample transport or analysis.

Agree the report-acceptance decision before sampling

Give each bidder the same acceptance schedule. For every analyte and sample point, record the approved criterion, unit, pressure or reference basis, method/version, reporting limit and agreed treatment of measurement uncertainty. The laboratory should identify any requirement it cannot assess.

• Match the report to the actual sampling location, assembly and operating state.
• Check method, edition, calibration information, reporting capability, deviations and the responsible laboratory.
• Keep a reported non-detect, a result below quantification and a measured numerical zero distinct.
• Require the report to identify the acceptance basis used for any conformity statement.
• Record an inconclusive or non-representative result as such; do not turn missing capability into a pass.

A purity class, a general filter certificate or an unqualified word such as “compliant” does not replace that sample-to-decision trail.

Confirm Australian delivery and the complete quotation

Before award, obtain the Australian sampler’s identity, laboratory location, method scope, chain-of-custody process, shipping and holding-time conditions, turnaround, report example and invalid-sample/retest policy. Ask for the complete price in an identified currency, including taxes, travel, equipment, freight, analysis and repeat work.

State contract duration, cancellation and refund terms, responsibilities for arranging safe access, and the person authorised to accept the final report. Australian on-site availability for the two examples remains unconfirmed by the cited pages; that limitation is part of the procurement decision, not evidence that the services are unavailable or unsuitable.
