【国外标准】 Standard Classification of Potential Health and Safety Concerns Associated With Thermal Insulation Materials and Accessories

4.1 The purpose of this classification is to identify potential concerns and effects which may occur during the life cycle (installation, service, removal, and disposal) of insulation materials and accessories resulting from direct contact or indirect action or events.4.2 This classification does not identify remedial or preventive steps that may be taken to correct potential problems or hazards; rather it is intended as a checklist that will make it easier to deal constructively with these potentials, and to determine what, if any, specific requirements need to be added to other standards concerning insulation materials or accessories. (See Appendix X2 for sources of information.)4.3 This classification recognizes that proper handling and installation procedures can substantially reduce the potential concerns and effects. Further, it recognizes that in some situations the presence or creation of potential effects or hazards results from an intervening act of human or natural origin, or depends on access to or contact with the materials or accessories. Lack of compatibility of the individual components of an insulation system with each other or the environmental conditions within which the system will operate, or both, may create unanticipated effects. (See Appendix X3.)1.1 This classification identifies potential concerns and effects that could result from direct contact with thermal insulation materials and accessories, or be caused by indirect action of events such as aging, fire, or physical disturbance.1.2 Intent of Classification: 1.2.1 It is the intent of this classification to alert others to potential concerns, effects, hazards, or risk.1.2.2 It is not the intent of this classification to establish the degree of risk or hazard or limiting values of potential hazards.1.2.3 It is not the intent of this classification to establish or recommend methods or markings to reduce or mitigate the potential; however, it is recognized that correct procedures and precautionary measures can substantially reduce or eliminate some of the potential concerns, effects, hazards, or risks.NOTE 1: See Appendix X1 for commentary.1.3 This classification recognizes the responsibility of producers and users, as appropriate, to: (1) provide information on known effects or hazards, (2) advise on established safety and health practices, and (3) determine applicable regulatory requirements.1.4 This classification does not address the health and safety concerns of thermal insulation materials and accessories during manufacture.1.5 Omission of an item from this classification does not imply an absence of potential concerns or effects.1.6 There is no importance in the order of listing.1.7 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.
