This specification does not include two-dimensional heat sealed poly(vinyl chloride) gloves. An approved lubricant for absorbable dusting powder may be applied to the gloves. Other lubricants may also be used, provided, that their safety and efficacy have been previously established. Both the inside and outside surface of the glove should be free of talc. All products should meet the required degree of sterility, freedom from holes, physical requirements before and after ageing, amount of powder on the glove, tensile strength and ultimate elongation.1.1 This specification covers certain requirements for poly(vinyl chloride) gloves used in conducting medical examinations and diagnostic and therapeutic procedures. It also covers poly(vinyl chloride) gloves used in handling contaminated medical material.1.2 This specification provides for poly(vinyl chloride) gloves that fit either hand, paired gloves, and gloves by size. It also provides for packaged sterile or nonsterile or bulk nonsterile poly(vinyl chloride) gloves.1.3 This specification does not cover two-dimensional heat sealed poly(vinyl chloride) gloves.1.4 This specification is similar to that of Specification D3578 for rubber examination gloves.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
