Are the garments suitable for use in cleanrooms?

We follow the IEST recommended practice which covers garment system considerations for cleanrooms and other controlled environments. (IEST-RP-CC003.3)
 
There are a number of recommendations regarding the construction of the garment, as well as the materials to be used in its construction. We use these guidelines as the basis for our own construction, e.g. the threads should be synthetic, non-particulating and suitable for sterilisation, and of the materials recommended, one is non-woven. Our garments are constructed on this basis. Additionally, there are a number of ways recommended for closing the seams on the garment. We choose bound seams as we find this is the best way to prevent particulation as this system completely seals the seams, stopping particulates from escaping.
 
Additionally, we conduct, according to the standard, particle shedding analysis using the Helmke drum test. The results are well under the limit set for category 2 on the Helmke Drum classification.
 
There are no solid rules, or pass / fail criteria for ISO Cleanroom compatibility. Much surrounding the suitability of Cleanroom consumables will depend on the manner in which they are used. For example, if the operator is sitting still for most of his or her working day, the likelihood is that their garment / gloves etc. will generate far less particulates than an operator who is constantly moving around while working.
 
What we do is to ensure that our garments are as particulate free as possible when they are packed. We also ensure that they are constructed in such a way as to minimise any opportunities for particulation to occur. In this was we can say that our garments are suitable for use in an ISO Class 4 cleanroom.

The packaging is printed with IPA resistant ink to ensure there is no contamination and each bag has an ‘easy-tear’ opening. The products are packed in a carton liner which is sealed with a twist tie to prevent contamination.
