Our in-house particle measurement adds room-air data to the assessment of surfaces. Sampling locations, room state and purpose need to align for a useful result. The measurement plan therefore comes before the evaluation.
What question should the measurement answer?
A baseline describes a condition. A before-and-after comparison needs comparable circumstances. An agreed classification assessment has specific scope requirements. We address these differences during project planning.
Understand ISO Class 8
ISO 14644-1 classifies air cleanliness by airborne particle concentration. Class 8 is one of these classes. It does not describe surface cleanliness or electrical safety. An indicative single measurement is not a complete classification assessment.
A target is not a result
If ISO Class 8 is agreed as the project target, the sampling plan, particle sizes and operating state are coordinated accordingly. Measured data determine whether requirements are met. Cleaning alone does not guarantee a class or constitute certification.
What particle counting cannot do
Counting does not determine chemical composition or biological characteristics. Fire incidents and unknown dust may require additional investigation. Data are therefore interpreted in the context of the site.
Frequently asked
Does COM.SAR perform the measurements itself?
Yes. Particle measurement is an in-house COM.SAR service. We agree the objective, scope and documentation with you beforehand.
