BS EN 1870-4:2012EN 1870-4:2012 (E) 6 Introduction This document has been prepared to be a harmonised standard to provide one means of conforming to t

32、he essential safety requirements of the Machinery Directive and associated EFTA regulations. This document is a type “C“ standard as defined in EN ISO 12100:2010. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this d

33、ocument. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of other standards, for machines that have been designed and built according to the provisions of this type

34、C standard. The requirements of this document are directed to manufacturers and their authorised representatives of multi-blade rip sawing machines. They are also useful for designers. This document also includes provisions and examples of information to be provided by the manufacturer to the user.

35、Common requirements for tooling are given in EN 847-1:2005+A1:2007. BS EN 1870-4:2012EN 1870-4:2012 (E) 7 1 Scope This document deals with all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to stationary multi-blade rip sawing machines, hereinafter refe

36、rred to as “machines”, designed to cut solid wood, chipboard, fibreboard, plywood and also these materials, if they are covered with plastic edging and/or plastic/light alloy laminates, when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseea

37、ble misuse; see also 6.3. This document does not apply to machines with vertical roller feed or vertical chain conveyor feed or machines designed to make the first rip cut on a log. This document does not deal with any hazards relating to the combination of single machines with any other machine as

38、part of a line. This document is not applicable to machines which are manufactured before the date of its publication as EN. NOTE Machines covered by this document are listed under 1.3 of the Machinery Directive. 2 Normative references The following documents, in whole or in part, are normatively re
