那搂主,你在的什么是A类标准吗/作者: zjh407 时间: 2011-11-19 23:02
For the purposes of its contract with the Commission, CEN has defined three types of
harmonized standard, A, B and C. This terminology is specific to the standards drafted
under the machinery Directive. Classes A, B and C do not have the same meaning under
other Directives, such as “construction products” (89/106/EEC as amended).35
-A standards deal with basic concepts concerning all machinery; standard EN 292 is an
example of this category;
- B1 standards deal with safety aspects concerning a range of machinery such as safety
distances, calculation methods for lifting equipment, etc.; examples of these are
EN 294 on safety distances and EN 563 on temperatures of touchable surfaces;
- B2 standards deal with components or devices, such as safety devices, which are used
on a wide variety of machinery; EN 281, on the design of pedals, is an example;
-C standards are “vertical” standards covering a single type of machinery.作者: fumsga 时间: 2011-11-19 23:02
为答谢三楼的英文答案，作点翻译，有不妥处请指正。
就标准化委员会约定目标的需要，CEN定义出三个协调的标准类型，A、B和C类标准。但这些分类术语只有对那些在机械指令下制定的标准适用。A、B和C类的定义在其他指令下不具有相同的意义，例如“建筑产品”(89/106/EEC as amended) .35等。
