1 1.1 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 Helmke- Drum-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.

2 1.2 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 possible. Hence the first and most important step is to equalise the starting condition: Our most important cleanroom fabrics will be decontaminated 50 times before testing to give realistic and practical results Those samples will be tested by international approved and neutral textile research institutes under equal conditions The gathered data is then used by our expert technical team to provide recommendations For your guarantee of continuous quality the most important tests will be repeated regularly by us air permeability testing device 2 triboelectrical behaviour 3 filter testbed

3 1.3 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, which includes a special test bench to evaluate rest contamination in accordance to modified ASTM F Additionally, a Helmke-Drum was added to the existing equipment. A filter testbench for the determination of the particle retention capacity for airborne particles is also an important part of the test set-up lamination visualization in the Body-Box 2 dastex own filter testbed for cleanroom textiles 3 special floor construction 4 Body-Box in usage 5 ASTM-Bench (with sample) 6 Helmke-Drum

11 1.6 SPECIAL REQUIREMENTS NEED SPECIAL TEXTILES Special finish for cleanroom textiles The garments must be prepared according to the applications within cleanrooms. For projects with extra demands on your cleanroom garments we offer textiles with special finishing. For some of our fabrics the following options are available: Water repellent finish Anti microbiological finish 1 Hydrophilic finish In addition we supply the Cleanroom fabric ION-NOSTAT BS which is, according to the manufacturer, flame resistant class Index 1 according to EN533 classified. Everything stays dry; water repellent finish 1 As part of the discussion is an anti microbiological finish in cleanroom garments in the sterile area worthwhile or a waste? see also the article in the trade magazine Reinraumtechnik Vol. 1/2006 (GIT publishing). Nano finish for cleanroom garments The finishing of cleanroom garments with nano particles is still in the early stages but initial tests have been quite successful. A dirt resistant Nano finish for cleanroom garments is already available. The roll-off effect of the Nano finish for cleanroom garments

12 1.7 NOMEX AND KEVLAR Certain work processes require not just product protection also the protection of the employee for risks as varied as flame and cut protection. In these cases dastex will work to develop a bespoke solution with the user based on his particular requirements. Our own prior experimentation in completed special projects help in the consultation process and can help to simplify the search for particular solutions. NOMEX and KEVLAR are DuPont trade marks. ESD/EPA FABRIC/GARMENT 1 Our already extensive choice of cleanroom garments also has additions in the area of ESD/EPA garments. Quite a few of our existing cleanroom garments (such as ION-NOSTAT-VI.2, ION-NOSTAT Plus, etc.) already fulfil typical ESD demands. There are circumstances within certain limit ranges, e.g. where cleanroom demands are mainly judged as low (or where possibly no criteria exist) where higher air permeable fabrics are used (also so called mixed fabrics ). Dastex can offer you a choice of products to cover these options Nomex filament fabric for cleanroom use 2 ESD coat 3 Fabric and coat tested at STFI and certified according to EN
