1.1  This document specifies the safety requirements and measures for —  cold presses, —  hot presses, —  bending presses, —  edge/face gluing presses, —  membrane presses, and —  embossing presses, where the pressing force is applied by hydraulic, pneumatic or electrical actuators pushing two flat or shaped surfaces against each other, capable of continuous production use, altogether referred to as “machines”. This document deals with all significant hazards, hazardous situations and events as listed in Annex A, relevant to machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer, including reasonably foreseeable misuse. Also, transport, assembly, dismantling, disabling and scrapping phases are taken into account. 1.2  This document is applicable to machines fitted with one or more of the following devices or additional working units, whose hazards have been dealt with: a)  a device for hot gluing; b)  a device for high-frequency gluing in the frequency range from 1 MHz to 400 MHz; c)  a device for high-frequency shaping in the frequency range from 1 MHz to 400 MHz; d)  an automatic workpiece loading and unloading system; e)  an intermediate additional platen; f)  a workpiece extractor; g)  a horizontal pressing system; h)  split moveable platens. 1.3  The machines are designed to process workpieces consisting of: a)  solid wood; b)  materials with similar characteristics to wood (see ISO 19085-1:2021, 3.2), except those with light alloy laminates/edges/profiles for high-frequency presses; c)  wood-based material such as chipboard, fibreboard and plywood composed/laminated with steel sheets/edges/profiles, except for high-frequency presses; d)  honeycomb board; e)  composite boards made from the materials listed above. 1.4  This document does not deal with any hazards related to: —  specific devices that differ from the list above; —  hot fluid heating systems internal to the machine other than electrical; —  any hot fluid heating systems external to the machine; —  operation of taking intermediate platens out and in again; —  the combination of a single machine being used with any other machine (as part of a line). 1.5  This document is not applicable to: —  frame presses; —  membrane presses where the pressing force is applied by vacuum only; —  presses for producing chipboard, fibreboard, OSB; —  machines intended for use in potentially explosive atmosphere; —  machines manufactured before the date of publication of this document.

This document specifies the safety requirements and measures for horizontal cutting cross-cut sawing machines with one saw unit (radial arm saws) with manual loading and/or unloading of the workpiece and capable of continuous production use, hereinafter referred to also as “machines”.

This document gives guidance on methods for determining and classifying the durability of wood and wood-based materials against biological wood-destroying agents.

The methods can be applied to individual wood species and processed wood-based materials, including thermally and chemically modified, and water-repellent impregnated wood. Examples of wood-based materials are oriented strand boards (OSB), particle boards, fibre boards, laminated veneer lumber (LVL), and plywood. However, this document is not intended to give guidance on methods for determining and classifying the durability of wood products, coated wood, and wood polymer composites.

Preservative-treated wood is not within the scope of this document, since requirements for the effectiveness of wood preservatives and durability requirements of wood treated with preservatives are regulated in several other European standards. However, this does not apply to modified wood, which is why it is included in the scope of this document.

The wood-destroying agents considered in this document are:

— wood-decay fungi (basidiomycete and soft-rot fungi);

— beetles capable of attacking dry wood;

— termites;

— marine organisms capable of attacking wood in service.

Data on the biological durability of the heartwood of selected wood species considered of economic importance in European countries are presented in Annex A (informative), which also provides information relating to their geographical origin, density, sapwood width and treatability.

NOTE Treatability, durability to disfiguring fungi, permeability to water and performance in use of wood and wood-based materials are also important issues. However, because standardized methods aiming to assess and classify these factors do not exist and/or have not been extensively experienced yet, preliminary guidance is given in Annex B (informative) for the classification of wood treatability with aqueous wood preservatives, Annex C (informative) for the classification of the permeability to water, and Annex D (informative) for the durability to disfiguring fungi.
