For example, heat-sealed or fused edges can reduce particle generation compared to stitched edges, and raglan sleeves can provide more freedom of movement than set-in sleeves.



  • Cleanliness level: The cleanliness level determines the degree of contamination control required for the garment system. It depends on the classification of the cleanroom or controlled environment, as well as the product or process sensitivity. The cleanliness level can be expressed in terms of particle size and concentration, airborne molecular contamination (AMC), or microbial contamination. For example, ISO 14644-1 defines nine classes of cleanrooms based on particle size and concentration, ranging from ISO Class 1 (the cleanest) to ISO Class 9 (the least clean). Iest rp cc003 4 pdf free provides guidance on how to select a garment system that meets or exceeds the cleanliness level required for your application.



  • Durability: The durability determines the lifespan and performance of the garment system. It depends on the quality and construction of the fabric and design features, as well as the frequency and method of cleaning, inspecting, repairing, and replacing the garments. Durability can be measured in terms of tensile strength, tear resistance, abrasion resistance, colorfastness, shrinkage, etc. Iest rp cc003 4 pdf free provides guidance on how to test and evaluate the durability of garments and how to establish a quality control plan for maintaining them.



  • Comfort: The comfort determines the user satisfaction and compliance with the garment system. It depends on the fit, feel, breathability, moisture management, thermal regulation, etc. of the fabric and design features. Comfort can be measured in terms of subjective feedback from users or objective parameters such as skin temperature, skin humidity, heat loss, etc. Iest rp cc003 4 pdf free provides guidance on how to measure and improve the comfort of garments and how to consider user preferences and ergonomics.



  • Cost: The cost determines the economic feasibility and sustainability of the garment system. It depends on the initial purchase price, the operating costs, and the environmental impact of the fabric and design features.
