Solid Particles
Particle counts at agreed compressed-air sampling points, reported against the particle-size ranges and requirements included in the test scope.
ISO 8573 Purity Compliance & Validation
Compressed Air Quality Testing
in South Africa
Test the compressed air reaching your industrial process. Fisher Installations scopes on-site testing in line with ISO 8573 for particles, pressure dew point and oil carryover, with results and observations for each agreed test point.

Agree the testing scope
Compressed air testing parameters
Food and beverage, packaging, pharmaceutical and manufacturing teams may need evidence of the air conditions reaching a process. The required parameters, purity limits and sampling points are agreed around that process before testing.
Pressure Dew Point
Pressure dew point measurement for dry compressed air, with the operating context and recorded result included in the report.
Oil Carryover
Oil carryover testing for the agreed compressed-air application. The measurement method, reporting basis and equipment suitability are confirmed in the scope.
Additional Process Requirements
Tell us if your process requires microbial sampling or other additional parameters so the required method and reporting can be reviewed before quotation.
Your process defines the requirement
Agree the purity requirements and the report before sampling.
Send the relevant process requirement or target purity class if it is available. We confirm which parameters and sampling points are included. The report states what was tested, where it was sampled and the conditions recorded.
| Before the visit | In the agreed report |
|---|---|
| Process or product requirement and target limits | Tested parameters, units and comparison with agreed requirements |
| Sampling-point locations and operating conditions | Sample identification, recorded conditions and results per point |
| Required methods and suitable instrument access | Test method, observations and relevant limitations |
| Site access, operating schedule and any known contamination | Findings and recommendations for any further investigation |
Air-quality deliverable
A report and observations for each agreed test point, with a Certificate of Conformance where included in the scope. Measured results are compared with the agreed requirements and reported with their test conditions and limitations.
Site coverage and planning
Fisher Installations is based in Gauteng. Other South African locations are scoped by arrangement, including travel and site access. For suitable prepared test points, indicative capacity is around three to four air-quality tests per day; the actual schedule depends on the agreed scope and site conditions.
Confirm instrument suitability
For the proposed testing setup, testing stops and findings are reported if pressure dew point exceeds 10°Ctd or oil exceeds 1 mg/m³, to protect the equipment. These are operating limits for that setup, not the target purity limits for your process. Disclose known contamination when requesting a scope.
Frequently asked questions
Air quality testing FAQs
What does compressed air quality testing include?
The proposed on-site service covers particles, pressure dew point and oil carryover, with a report and observations per agreed point. Additional process requirements are reviewed when the scope is prepared.
Which compressed air purity class should we test against?
Share your process, customer or equipment requirement and any specified target class. The parameters, limits, methods and sampling points must be agreed before testing so the report answers the relevant process question.
Do you test compressed air at sites across South Africa?
Fisher Installations is based in Gauteng, with other South African locations scoped by arrangement. Send the site address, number of sampling points and operating schedule so access, travel and testing requirements can be confirmed.
How long does compressed air quality testing take?
For suitable prepared sampling points, indicative capacity is around three to four tests per day. The number of points, required methods and site conditions determine the schedule. Report timing is agreed in the quotation.
Do I receive a report or Certificate of Conformance?
The agreed deliverable includes measured results and observations per test point, with a Certificate of Conformance where included in scope. The report identifies the requirements used for comparison and any relevant test limitations.
What information should I send to request a test?
Send the site location, industrial application, intended sampling points, operating pressure, known air-treatment details and the required purity limits or process specification if available. Include any known contamination or access constraints.
