IMPORTANT INFORMATION ABOUT CLEANROOM GARMENTS Cleanroom garments – the most important filter between human and product Humans are the biggest source of contamination in the cleanroom. This is the reason why high quality cleanroom garments are absolutely essential for protection of the product. The following aspects should therefore be considered when choosing garments: technical features of the Cleanroom fabric wearing comfort and physiological characteristics garment construction, e.g. the quality of the seams, the fitting etc. In order to have an optimal running “system of cleanroom garments” (chapter 1.3) it is necessary that all the individual demands on the cleanroom garments be checked with the requirements of the user at their workstation. Only once this is done the filter between human and product can become effective. Trust in our competence Making a decision as to which system gives an optimal solution for your cleanroom is not always easy. For this reason we offer our extensive experience within the field. In order to provide the perfect solution for you, we have devised the following procedures to make the choice of appropriate products easier. Amongst them are: Tests of fabrics under a standardised dastex procedure Co-operation with independent institutes to prove our quality standards Assembly and continuous development of our own test cleanroom (Body-Box, chapter 1.3) including the ability to test cleanroom products with the use of the HelmkeDrum-Method or the modified ASTM F51-68 test methods Supply of technical data provided by the manufacturer Despatch of samples to our customers for in situ testing Complete technical back-up from our in house experts Links, via dastex, to a world-wide network of leading cleanroom product manufacturers This grants our customers complete information for all quoted products, and a high level of confidence whenever an order is placed.

YOU CAN TRUST OUR STANDARDS Quality of fabric: we test under representative conditions Due to a lack of standards and regulations for cleanroom products it is nearly impossible for end users to evaluate cleanroom garments on the basis of technical data sheets. There is also the problem that each of the product manufacturers will use a different testing method. This is why, in co-operation with a number of approved institutes, we have developed our own standards to enable our clients an objective assessment of all our cleanroom garments. Our aim is to make a realistic comparison of single products...

WE KEEP DEVELOPING FOR YOU: DASTEX BODY-BOX Cleanroom garments as a system In the desire to continuously develop our cleanroom garments further in all areas, dastex invested in 2004 / 2005 in an own test cabin, a so called Body-Box. In here whole garment systems, as well as single garment components, can be tested for their rates of particle shed. During the development, in co-operation with CCI – von Kahlden GmbH, greatest importance was placed in the highest possible reproducibility of the test results. Beside the Body-Box (in accordance with IEST-RP-CC003.3) a cleanroom cabin was installed,...
