Overview

EN 1870-5:2002+A2:2012 (equivalent to EN 1870-5:2002+A2:2012) is the European harmonised Type C standard for the safety of woodworking machines specifically addressing circular sawbenches and up‑cutting cross‑cut sawing machines. It covers significant hazards, hazardous situations and events (see Clause 4) for machines designed to cut solid wood, chipboard, fibreboard, plywood and these materials when covered with plastic edging or laminates, when used as intended or under reasonably foreseeable misuse. The standard incorporates Amendments A1 (2009) and A2 (2012) and supports conformity with the EU Machinery Directive (see informative Annex ZA).

Key topics and technical requirements

• Scope and exclusions: excludes hand‑held motor tools (and bench‑mounted adaptations), small bench/table machines liftable by one person, and-for CNC machines-EMC hazards are not covered in this document.
• Hazard listing: clause structure identifies mechanical and non‑mechanical hazards relevant to circular sawbenches/up‑cut cross‑cut machines.
• Safety requirements (Clause 5): general safety measures, control design, mechanical protection, and protection against non‑mechanical hazards (e.g., electrical, ergonomic, noise).
• Information for use (Clause 6): marking, instructions, and user information required from manufacturers.
• Normative tests and annexes (A–H): prescriptive test methods and criteria such as stability tests for open‑frame machines, saw spindle tolerances, riving knife strength and stability tests, saw blade guard stability and impact tests, and brake tests.
• Normative references: cross‑references to standards such as EN 60204‑1 (electrical equipment), EN 847‑1 (woodworking tooling), EN 1037 (prevention of unexpected start‑up), and EN 60529 (IP code) for complementary requirements.

Practical applications and who uses it

• Machine designers and manufacturers: to design, test and document circular sawbenches and up‑cut cross‑cut sawing machines that meet EU essential requirements.
• Suppliers, importers and conformity assessors: to demonstrate conformity with the Machinery Directive and support CE marking.
• Test laboratories and certification bodies: to perform the normative stability, guard impact and brake tests detailed in the annexes.
• Safety engineers, workshop managers and purchasers: to assess hazards, specify safe equipment and verify user information and guarding systems.

Related standards and compliance

• Harmonises with the EU Machinery Directive 2006/42/EC (see Annex ZA).
• Complements general safety standards such as EN ISO 12100 (risk assessment & design principles) and the tooling and electrical standards cited in its normative references (e.g., EN 847‑1, EN 60204‑1).

This may be e.g. a double spanner arrangement, or an integral locking bar inserted through the spindle. This bar shall have a minimum diameter of 8 mm and be made from steel with an ultimate tensile strength of at least 350 N mm-2. Locking bars shall prevent the spindle from rotating if the spindle drive motor is inadvertently switched on. Verification: By checking the relevant drawings, inspection measurement !deleted text" and relevant functional testing of the machine. Alternatively on machines with locking bars, by the following test: After starting the spindle drive motor with the locking bar in place the spindle shall remain stationary. !NOTE For the ultimate tensile strength a confirmation from the manufacturer of the material can be useful." 5.3.3.3 Saw blade fixing device Saw flanges (or in the case of flush mounted saw blades - a flange) shall be provided. For saw blades with a diameter ≤ 450 mm the diameter of both flanges (or flange for flush mounting) shall be at least D/4 (where D = the maximum diameter of the saw blade for which the machine is designed).
