Clean room certification - the key to clean room safety

What is a Clean Room and why does it matter?

In environments requiring the utmost sterility - laboratories, hospitals, pharmaceutical plants or electronics factories - even the slightest contamination can lead to serious consequences. Every piece of equipment, including lighting, must meet stringent cleanliness standards.

A Clean Room is a space with a controlled number of particles in the air, where the international standard ISO 14644-14 is the gold standard for assessing the emissions of the equipment installed there. This is not just a formality - it is a guarantee that the product will not interfere with precise processes requiring sterile conditions.

ISO 14644-14: Necessary certification confirmed by tests

Clean Room certification is concrete confirmation of compliance with international requirements, backed up by robust laboratory testing. Our LED luminaires for clean rooms, including COMPACT LED HYGIENIC, have passed comprehensive particle emission tests carried out by an independent laboratory.

Confirmed test results:

The COMPACT LED HYGIENIC luminaire has received certification that it is suitable for use inside clean rooms with an ISO air purity class of 3-9 according to ISO 14644-1:2015. This is the highest possible standard, covering even the most demanding environments where a minimum number of microscopic particles in the air is tolerated.

Why is certified lighting essential?

In clean rooms, even microscopic contamination can cause:

Costly production downtime
Damage to sensitive components
Contamination of pharmaceutical products
Health hazard to patients
Financial losses in the thousands of euros

Improperly designed lighting fixtures can release particles from seals, housings or electronic systems - so choosing certified lighting is not an option, but a necessity.
