EN 1870-4:2012 (E) 6 Introduction This document has been prepared to be a harmonised standard to provide one means of conforming to the 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 document. 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 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. Common requirements for tooling are given in EN 847-1:2005+A1:2007. SIST EN 1870-4:2012



EN 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 referred 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 foreseeable 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 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 referenced in this document and are indispensable for its application.

The saw blades can be mounted on one or more saw spindle(s) which may be capable of vertical adjustment. The saw blades may be capable of axial adjustment either relative to the spindle or together with the spindle. The saw blade spindle(s) may be arranged so that they are: a) all mounted above the workpiece support; b) all mounted below the workpiece support; c) mounted both above and below the workpiece support. The cutting mode can be ‘against the feed’ or ‘climb cutting’ or a combination of both (see Figure 1).
