PESO approval applies to defined hazardous premises under Indian petroleum and explosives rules.
- 02

- 03
Match protection type and zone: PESO guidance distinguishes flameproof, intrinsic-safety, encapsulation, increased-safety and non-sparking uses.

What to check before relying on this certification
Certification is normally limited to a named model, configuration, standard and use. These checks turn a marketing claim into a procurement record.
- 01
Find out whether local law, your insurer or your project specification requires this approval, or whether it is optional.
- 02
Verify the exact product, standard, certificate holder and current public-register status.

Check local language, importer, installation, inspection and authority requirements.
- 04
Do not substitute a similar international certificate without written acceptance from the authority or specifier.
