This document shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2008 and conflicting national standards shall be withdrawn at the latest by June 2009. This document together with EN 1870-13:2007 supersedes EN 1870-2:1999. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the Machinery Directive. For relationship with EU Directive, see informative Annex ZA, which is an integral part of this document. Organisations contributing to the preparation of this European Standard include the European Committee of Woodworking Machinery Manufacturers Association “EUMABOIS“. The European Standards produced by CEN/TC 142 are particular to woodworking machines and complement the relevant A and B Standards on the subject of general safety (see introduction of EN ISO 12100-1:2003 for a description of A, B and C standards).

This document is a type C standard as defined in EN ISO 12100-1:2003. The machinery concerned and the extent to which hazards, hazardous situations and events 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 vertical panel sawing machines. This document is also useful for designers and importers. This document also includes provision 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. 1 Scope This document deals with the significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to manually loaded and unloaded vertical panel sawing (with or without integrated feed) machines fitted with: the facility for scoring; an angle cutting device; a middle support device; a programmable stop for parallel vertical cuts; the facility for grooving with a width of at most 20 mm in one pass by using a milling tools, hereinafter referred to as “machines“ when they are used as intended and under the conditions foreseen by the manufacturer. The machines are designed for cutting panels of the following materials: a) wood based materials such as chipboard, fibreboard, plywood and also these materials where they are covered with plastic / light alloy laminates; b) solid wood; c) hardened rubber and hardened plastic material; d) non ferrous materials e.g. light alloy; BS EN 1870-14:2007 Copyright British Standards Institution Provided by IHS under license with BSI - Uncontrolled Copy Licensee=Boeing Co/5910770001 Not for Resale, 08/14/2008 20:21:58 MDTNo reproduction or networking permitted without license from IHS -,-,- EN 1870-14:2007 (E) 7 e) compound materials with core consisting of polyurethane or mineral material laminated with light alloy. This document does not apply to vertical panel saws with pressure beam and saw unit mounted behind the workpiece support. This document does not deal with hazards relating to the combination of a single machine being used with any other machine (as part of a line). This document is not applicable to vertical panel saws which are manufactured before the date of its publication as EN. NOTE Machines covered by this standard are listed under A.1.4 of annex IV of the Machinery Directive. 2 Normative references The following referenced documents are indispensable for the application of this document.
