Compressor testing and certification
Machinery that produces compressed air or gas.
Compressor — conformity scope
For compressors, machinery safety and pressure equipment requirements are assessed together; the air tank follows a separate route according to its own category. Noise and electrical equipment are other headings in the file. In-service equipment also carries a periodic inspection obligation.
The list below is the European Union framework. The same product falls under a different mark and approval regime in another market; Smart Service Finder shows that market's requirements when you select it.
Regulation
Compressor legislation that typically comes into play for
The following is the European Union framework and shows typical application. Which title actually applies depends on the class, intended use and components of the product; The scope is determined by examining the product.
Risk assessment, essential health and safety requirements and a technical-file obligation.
Replaces 2006/42/EC, mandatory on 20 January 2027 with no further transition period.
Electrical safety under the Low Voltage Directive.
Emission and immunity are assessed together.
The Pressure Equipment Directive for pressurised parts; the category is determined by pressure and volume.
Sound-power-level declaration and marking for compressors used outdoors.
Refrigerant type, GWP value and leak-tightness obligations for systems containing a refrigerant.
What is required?
Each item links to the relevant service page: the legislation entry to the certification scheme, the test family to the laboratory page, and the mark to the market page.
European Union — required mark
5- CE — European UnionThe umbrella for entering the EU market; all regulations applicable to the product are met.
- LVD — European UnionLow Voltage Directive — no notified body; the declaration is made by the manufacturer.
- EMC — European UnionElectromagnetic Compatibility Directive — emission and immunity requirements.
- PED — European UnionPressure Equipment Directive — the NB's role increases as the category rises.
- ATEX — European UnionExplosive atmosphere equipment — NB is mandatory for category 1 and electrical category 2.

How does the process work?
The flow below is a general order independent of product type; timing and acceptance criteria are determined by the standard the product falls under.
1Defining the scope
It is determined which legislation the product falls under based on its technical characteristics and intended use.
2Testing and evaluation
Tests are planned for the applicable headings; results are evaluated according to the relevant standards.
3Technical file
Design, production and test records are compiled in the technical file, accompanied by a risk assessment.
4Declaration or certificate
Depending on the product group, the manufacturer's declaration is prepared or third-party certification is carried out.
Compressor which market is it going to?
Who bears the obligation, where the test will be performed, and what customs will require all vary by market.
What changes depending on the market?
Same product, different regimen
- European UnionUnder the CE mark, the Machinery Directive, LVD, EMC and PED for pressurised parts are assessed together; performance is measured under ISO 1217.
- United KingdomThe UKCA regime carries the same technical requirements into its own legislation; CE marking is recognised indefinitely for many product groups.
- United StatesPressurised parts under the ASME BPVC, electrical safety under UL, and the API 617 specification apply.
Products in the same group
Compressor — let's work out the scope together
Share the product's technical characteristics; let us tell you in writing which headings apply to your scope and which tests are required.
This result is a starting roadmap, not a conformity assessment. Which legislation a product falls under depends on its technical characteristics, intended use and user group; it is only finalised by examining the product. You may have an obligation not shown in the list, and an item shown here may not apply to your product.
