(Specification)Standard Performance Specification for Protective Clothing Worn by Operators Applying Pesticides
Standard Performance Specification for Protective Clothing Worn by Operators Applying Pesticides
ABSTRACT
This specification establishes the minimum performance, classification, and labeling requirements for protective clothing worn by operators applying pesticide products, primarily field strength, in liquid form. It addresses protection provided by protective clothing items that include, but are not limited to, liquid-tight or spray-tight garments, coveralls, jackets, shirts, and pants, with the exception of those used for the protection of the head, hands, and feet. It does not cover protection against biocides, fumigants, or highly volatile liquids. All protective clothing shall be tested and classified by the level of protection based on material, seam, and garment requirements. These requirements include liquid penetration resistance, resistance to penetration by liquid under pressure, resistance to permeation, breaking strength, and tearing strength. The garments shall be supplied with permanent labels and sheets detailing instruction for use, product technical information, and chemical resistance information.
SCOPE
1.1 This specification establishes minimum performance, classification, and labeling requirements for protective clothing worn by operators applying pesticide products, primarily field strength, in liquid form.
1.2 Protective clothing items covered by this specification include, but are not necessarily limited to, liquid-tight or spray-tight garments, coveralls, jackets, shirts, and pants.
1.3 This specification addresses protection provided by protective accessories, with the exception of those used for the protection of the head, hands, and feet.
1.4 This specification does not address protection against biocides, fumigants, or highly volatile liquids.
1.5 The values given in SI units are to be regarded as the standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

It is possible that additional tests such as permeation resistance testing with the actual test chemical will be necessary to characterize fully the material for a particular
application. When additional tests to determine permeation are required, the penetration by liquid under pressure shall be replaced by the permeation test.
