13、 bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental

14、 and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directiv

15、es, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies

BS ISO 27065:2011ISO 27065:2011(E) ISO 2011 All rights reserved vIntroduction This International Standard addresses the performance requirements for protective clothing worn by operators applying liquid pesticide products diluted with w

18、ater. These products are also known as crop protection and plant protection products in certain countries. Registration of pesticide products, such as insecticides, herbicides and fungicides, involves the assessment of operator exposure and risk, factors which determine the need for personal protect

19、ive equipment. Protection needs to correspond to the identified risks in order to avoid loss of comfort due to over-protection. Actual field trials are used to determine the operator risk while spraying pesticides under different scenarios. For the performance specification, data from field studies

20、are used to categorize the garment performance and determine the minimum performance limits for the different levels. Laboratory tests, including accelerated tests, are used to determine whether the garment met the minimum requirements for that level. The minimum penetration requirements, evaluated

21、by laboratory tests, are based on extensive studies comparing field study data with laboratory data. Laboratory data are often derived from accelerated tests to differentiate between different levels of performance; therefore, laboratory data cannot be used for direct comparison with field data or a

22、cceptable mitigation factors. This International Standard defines performance requirements for three levels of protective clothing with specified resistance to penetration by pesticide products. It is up to the manufacturer of a specific pesticide product to indicate on the label the recommended lev

23、el of protection (no protective clothing, Levels 1a, 1b, 2, 3) for the respective exposure conditions. A brief description of the different levels is given below. Level 1 garments are suitable when the potential risk of contamination is relatively low. The performance requirements for Level 1a garme

24、nts have been developed in view of low spray drift landing on the operator, e.g. from tractor boom sprayers. The performance requirements for Level 1b garments have been developed based on the performance of cotton and polyester/cotton garments, which are widely used for operator exposure studies. L

25、evel 2 garments are suitable when the potential risk of contamination is higher but not so high as to require the use of liquid-tight materials. Level 3 garments are suitable for use when the potential risk of contamination requires use of garments made with liquid-tight materials. This level is sui

26、table for high-exposure scenarios where it has been determined that garments that prevent liquids from penetrating/permeating provide adequate protection. This International Standard is intended for fabric and garment manufacturers, for manufacturers of pesticide products, trainers, regulators and o

27、ther individuals or organizations that make decisions regarding protective clothing for protection against pesticide products.

28、 worn by operators applying liquid pesticides 1 Scope This International Standard establishes minimum performance, classification, and labelling requirements for protective clothing worn by operators applying liquid pesticide products diluted in water. Protective clothing covered by this Internation

29、al Standard includes, but is not limited to, shirts, jackets, trousers, coveralls, and spray-tight or liquid-tight garments. This International Standard addresses protection provided by protective accessories, with the exception of those used for the protection of the head, hands, and feet. This Int

30、ernational Standard does not address protection against biocides, fumigants or highly volatile liquids. 2 Normative references The following referenced documents are indispensable for the application of this document.

Protective clothing materials do not include materials used in the construction of integral visors, gloves, and footwear. 3.11 re-usable chemical protective clothin

46、andard shall fulfil the requirements of ISO 13688 and shall be tested and classified by level of protection in accordance with the material, seam and garment requirements in Clauses 5, 6 and 7. Table 1 provides a summary of the tests to be conducted for each level of protection. NOTE The stringency

47、in testing requirements increases for each level. Therefore, any Level 2 garment necessarily meets Level 1a and Level 1b requirements, and so does not need to be tested to achieve that level of protection. Similarly, any Level 3 garment necessarily meets Level 1a, Level 1b, and Level 2 requirements.

48、 The materials and seams of Level 1a and Level 1b garments shall demonstrate a minimum level of liquid penetration resistance when tested in accordance with the tests specified in Table 1. The mechanical strength performance requirements are the same for all levels of garments. Garments shall pass a

49、 practical performance test. The material and seams of Level 2 garments shall demonstrate a higher level of liquid penetration resistance than Level 1 garments. The mechanical strength performance requirements are the same for all levels. The garments shall pass a practical performance test prior to being submitted to a low-level spray test of the whole garment. The materials and seams of Level 3 garments shall demonstrate a minimum level of resistance to penetration by liquids under pressure. If, for a p
