Our new capacity: Environmental testing in controlled areas

At Techmaster, we continue to expand our technical scope to better serve our clients.
Our newly accredited environmental testing capabilities ensure cleanrooms and controlled areas meet strict ISO 14644 and ISO/IEC 17025 standards.
These services help industries like pharmaceuticals, electronics, and medical manufacturing maintain product safety and quality under precise environmental conditions.

Why Controlled Environments Matter

In highly regulated industries, cleanliness and precision are non-negotiable.
Controlled areas ensure that every process occurs under specific environmental conditions.
In addition, these environments help protect products from contaminants such as dust, microorganisms, aerosols, and chemical vapors — all of which can seriously compromise safety and quality.

Moreover, cleanrooms must regulate key parameters like temperature, humidity, and pressure.
By maintaining these factors within tight limits, companies reduce risk and ensure consistency across production cycles.

What Is a Cleanroom?

Technically, a cleanroom is a space where incoming air is filtered and continuously recirculated through HEPA or ULPA filters.
This process removes contaminants and keeps particle concentration within defined limits.

Cleanrooms are classified by the number and size of particles per cubic meter of air.
According to ISO 14644-1, there are nine classes, ranging from ISO Class 1 (the cleanest) to ISO Class 9 (equivalent to normal room air).

Our Accreditation and Standards

Our environmental testing services operate under the accreditation scope of ISO/IEC 17025:2017 and ANSI/NCSL Z540-1-1994 (R2002).
These standards guarantee technical competence, reliability, and traceability.
Additionally, our tests comply with ISO 14644:2015, ensuring that your cleanroom meets global performance and cleanliness criteria.
