This International Standard gives test methods to determine the dimensional variance between elements of laminate floor coverings in a manufactured free-standing shape (unrestricted) in respect to thickness, length, width, squareness, straightness, width flatness, length flatness, openings between assembled elements and height differences between assembled elements.

NOTE These test methods are also applicable to other mechanically assembled panels e.g. modular multilayer floorings.

This document specifies the characteristics of cladding profiles and tiles made from cellulose-based materials and thermoplastics, usually called wood-polymer composites (WPC) or natural fibre composites (NFC), for external use.

This document is applicable to extruded profiles but also to tiles manufactured by other plastics processing techniques, e.g. injection moulding.

It is not applicable to support rail profiles, cover strip profiles and fastener devices.

This document also specifies assessment methods, provisions for the assessment and verification of constancy of performance (AVCP) of these products and includes requirements for marking.

Reprocessed and/or recycled materials can be used for manufacturing the components which comply with the requirements of this part of EN 15534.

NOTE 1 WPC materials are recyclable materials which can be treated in a material recovery process intended to save resources while minimizing harmful emissions into air, water and soil as well as their impacts on human health.

NOTE 2 A scheme for the characterization of plastics waste is given in EN 15347 and guidelines for the recovery and recycling are given in ISO 15270.

This part of ISO 19085 gives the safety requirements and measures for stationary four‐sided moulding

machines with a maximum working width of 350 mm and a maximum speed of the integrated work‐piece

feed of 200 m/min, hereinafter referred to as “machines”, designed to cut solid wood and materials with

similar physical characteristics to wood (see ISO 19085‐1:2017, 3.2).

It deals with all significant hazards, hazardous situations and events as listed in Clause 4 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.

NOTE 1: For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010.

It is also applicable to machines fitted with one or more of the following devices / additional working

units, whose hazards have been dealt with:

 universal spindle;

 glass bead saw unit;

 fixed or movable work‐piece support;

 quick tool changing system;

 laser marking unit;

 automatic work‐piece returner;

 in‐feed hopper;

 loading magazine;

 unloading table.

This part of ISO 19085 does not deal with any hazards related to:

a) in‐feed devices other than in‐feed hopper and loading magazine;

NOTE 2: For mechanical in‐feed devices which also prevent access to the in‐feed opening, see 6.6.4

b) out‐feed devices other than unloading table, except for hazards related to ejection from the machine

due to climb cutting;

c) out‐feed of work‐pieces on machines with feed speed higher than 60 m/min;

d) machines being used in combination with any other machine (as part of a line).

It is not applicable to machines intended for use in potentially explosive atmosphere and to machines manufactured prior to its publication
