30、 1978 3 Plastics glazing characteristics 3.1 General. A plastics glazing product is defined by its principal and secondary characteristics. (See 3.2 and 3.3 for a complete list applying to all plastics glazing products.) Although a change in principal characteristics implies a new type of product, i
31、t is recognized that, in certain cases, a change in shape and dimension does not necessarily require a complete set of tests to be carried out. Specimens of plastics exhibiting differences only as regards the secondary characteristics referred to in 3.3 may be considered as of the same type; certain
32、 tests are explicitly stipulated in the test conditions. NOTEDegree of safety. One plastics glazing material may be superior for protection against one type of hazard while another may be superior against another type, although they may vary in some of their more general properties. Since accident c
33、onditions are not standardized, no one type of plastics glazing material can be shown to possess the maximum degree of safety under all conditions and against all conceivable hazards. 3.2 Principal characteristics. For the purposes of this British Standard the principal characteristics (see 2.9) sha
34、ll be as follows: a) the trade name or mark of the manufacturer to indicate the process of manufacture; b) the nature and manufacturer of the material (polymethyl methacrylate, polyvinyl chloride, polycarbonate, etc.); c) the shape and dimensions (length, width, radius of curvature); d) the number o
35、f layers of material; e) the nominal and combination thickness; f) the special treatment of the material. 3.3 Secondary characteristics. For the purposes of this British Standard the secondary characteristics (see 2.10) shall be as follows: a) the colouring of the material; b) the method of manufact
36、ure of the product; c) the surface treatment of the product. 4 General requirements 4.1 General. The tests described shall determine whether a plastics glazing material has certain desirable properties for its acceptance as being suitable for vehicle glazing. SAFETY NOTE. Minimizing personal injurie
37、s. It is essential that all plastics glazing products are such that in the event of fracturing, the danger of personal injuries is reduced to a minimum. 4.2 Categories of plastics glazing materials. For the purposes of this standard plastics materials used for the glazing of motor vehicles and their
38、 trailers shall be divided into eight categories, as follows. a) Category A: maximum impact with optical requirement. Plastics glazing materials that comply with the requirements for rigid plastics materials that may be used in any allowed location. b) Category B: medium impact with optical requirem
39、ent. Plastics glazing materials that comply with the requirements for rigid plastics materials that may be used in any allowed location including partitions and forward facing windows, the inner surfaces of which are at an angle greater than 30 to the longitudinal vertical plane of the vehicle. c) C
40、ategory C: minimum impact with optical requirement. Plastics glazing materials that comply with the requirements for rigid plastics materials that may be used in any allowed location not requiring a higher level of impact performance. d) Category D: maximum impact with no optical requirement. Plasti
41、cs glazing materials that comply with the requirements for rigid plastics materials that may only be used in an allowed location not required for driving visibility. e) Category E: medium impact with no optical requirement. Plastics glazing materials that comply with the requirements for rigid plast
42、ics materials that may only be used in an allowed location not required for driving visibility including partitions and forward facing windows, the inner surfaces of which are at an angle greater than 30 to the longitudinal vertical plane of the vehicle. f) Category F: minimum impact with no optical
43、 requirement. Plastics glazing materials that comply with the requirements for rigid plastics materials that may be used in any allowed location not required for driver visibility nor requiring a higher level of impact performance. g) Category G: flexible with optical requirement. Plastics glazing m
44、aterials that comply with the requirements for flexible plastics materials that may be used in any allowed location.

45、exible with no optical requirement. Plastics glazing materials that comply with the requirements for flexible plastics materials that may only be used in an allowed location not required for driving visibility. 4.3 Environmental resistance. The material shall be resistant to the incidents to be expe
46、cted in normal traffic and to atmospheric and heat conditions, chemical action and abrasion. NOTE 1The abrasion resistance of post-coated components is judged on the basis of similarly post-coated flat sheet test pieces. In the design of these components it is, therefore, necessary to ensure that th
47、e shape and design does not make any subsequent coating operation difficult to achieve, thus giving rise to areas of the surface that have differing abrasion resistance characteristics. NOTE 2This standard includes requirements relating to durability of plastics safety glazing materials. If, however
48、, materials are subjected to exceptional or unusual circumstances such as undue scratching or abrasion, unsatisfactory methods of cleaning, chemical attack, or excessive ultraviolet radiation from an artificial source, the durability may be affected. If it is required to make provision for such circ
49、umstances, additional requirements should be agreed between the purchaser and the vendor. NOTE 3This standard does not cover practices or methods of mounting glazing materials. In general, plastics materials have higher coefficients of expansion than glass and therefore require more care in the design mounting arrangements. In addition, plastics materials may be hygroscopic and would be subject to dimensional change in service. It is therefore essential that materials are installed under normally expected conditions of temperature and humidity. 4.4 Ma
