11、 Practice 005.4 Gloves and Finger Cots Used in Cleanrooms and Other Controlled Environments IEST-RP-CC005.4 1 SCOPE AND LIMITATIONS 1.1 Scope This Recommended Practice (RP) describes procedures for testing and evaluating gloves and finger cots used in cleanrooms and other controlled environments. Te

12、sts are provided for determining cleanliness, physical and chemical integrity, and other relevant properties. Guidelines are also provided to assist users in the proper selection of gloves or finger cots. 1.2 Limitations It is impractical to design and manufacture gloves or finger cots to meet all r

13、equirements of every application. Therefore, the user should base the selection of gloves and finger cots on the requirements of the process, the analytical data resulting from evaluation testing, and the product data provided by the manufacturer. The application for which a glove is intended should

14、 determine which tests are appropriate and relevant. 2 REFERENCES The cited editions of the following documents are incorporated into this RP to the extent specified herein.

46、nmental Sciences and Technology IEST-RP-CC005.4 4 BACKGROUND AND PURPOSE Gloves and finger cots are used in cleanrooms both to ensure the safety of the workers and to preserve the cleanliness of the process and product. This RP provides methods for testing gloves and finger cots in two broad categor

47、ies: physical attributes and cleanliness. Whenever appropriate, suitable methods already existing in the literature are cited; when necessary, new test methods have been developed. 5 PHYSICAL CHARACTERISTICS OF GLOVES AND FINGER COTS Cotton, wool, asbestos, and any other materials likely to release

48、and generate particles should not be used in coverings intended for use in cleanrooms. Powdered gloves or gloves lined with flocking are not recommended. Findings on gloves are discouraged. If findings are used, they should be designed to minimize the generation or entrapment of particles. Conductiv

49、e fibers or fibers made conductive by the addition of conductive materials should be checked to confirm they will not be incompatible with the chemicals expected to be encountered during use. Gloves worn in cleanrooms should be long enough to cover the cuff of the cleanroom garment, overlapping by 2.5 cm (1 in.) or more. Available ASTM standards provide a range for standard sizes for rubber surgical gloves (ASTM D3577), rubber examination gloves (ASTM D3578), and finge
