Overview of Compressed Air Quality Testing (ISO 8573)

Tested by: NABL-accredited partner lab
Regulation: ISO 8573 & GMP
Typical turnaround: 5–7 days after sampling
Sampling: On-site sampling at use points

Compressed air is used to blow bottles, convey powders, cut and shape food, fill and seal packs and drive pneumatic valves. Where it touches the product or packaging, it is effectively an ingredient. Compressors draw in dust and moisture and can add oil, and pipework can grow microbes, all of which can end up in the product.

ISO 8573-1 classifies air purity by particles, water (pressure dew point) and total oil, and ISO 8573-7 covers microbes. Food and pharma auditors, global brand owners and GFSI schemes expect the quality of product-contact air to be defined and verified. Testing at the points of use, not just at the compressor, shows what reaches the product.

How we handle Compressed Air Quality Testing (ISO 8573)

1
Assessment of requirement
We confirm the standard, the list of tests and how many samples your product needs.
2
Sample collection
We collect the samples from your factory or warehouse, or tell you exactly where to send them.
3
Right lab assigned
We choose an accredited lab (NABL, BIS-recognised or ILAC) that covers your standard and can start soonest.
4
Testing
The lab tests your samples against the standard. We follow up and tell you at once if a test fails.
5
Test report
You receive the signed test report, ready to use for BIS, WPC, CE or your buyer.

What the lab tests

Parameter	Why it is checked
Particles	Particle count by size class
Pressure dew point	Water vapour content
Total oil	Aerosol, liquid and vapour
Microbes (ISO 8573-7)	Viable bacteria, yeast and mould
Process gases	Nitrogen and CO2 purity where used in packing

The final list depends on your product, its standard and the purpose of testing. We confirm it with you before the sample goes to the lab.

Frequently asked questions

Which air purity class does a food plant need?

It depends on whether the air touches the product directly, indirectly or not at all. Industry codes for food-grade air recommend strict classes for direct contact; we help you define them in your HACCP plan and verify them.

Will FSSAI and buyers accept the report?

Tests are done in labs accredited by NABL for the parameters reported, and for regulatory use in FSSAI-notified labs, which is what FSSAI, food safety officers and most buyers expect. For export, we match the lab to the importing country’s or buyer’s requirement.

Who carries out the testing?

Instacertify’s partner laboratories, accredited by NABL to ISO/IEC 17025 for the parameters on your report. We choose the lab, arrange the sample, follow up until the report is issued and explain the results to you.
