prEN ISO 19085-8 is a draft CEN/ISO safety standard for wide belt sanding machines and surface treating machines capable of continuous production use. It specifies safety requirements and protective measures for design, controls, safeguarding, tests and instructions so these woodworking machines can be operated, adjusted, maintained, transported and scrapped with foreseeable misuse taken into account.
What does prEN ISO 19085-8 specify?
prEN ISO 19085-8 covers the safety requirements for wide belt sanding machines and surface treating machines used on flat workpieces of even thickness, such as panels, beams and frames. It applies to machines intended for continuous production use and to selected additional working units and devices fitted to those machines.
The document organizes the requirements into four main clauses: controls in Clause 4, mechanical hazards in Clause 5, other hazards in Clause 6, and information for use in Clause 7. Annex A lists the significant hazards, Annex B summarizes the required performance levels, and Annexes C to G provide the test methods used to verify specific safety functions and protective devices.
| Annex | What it covers |
|---|---|
| A | List of significant hazards |
| B | Performance level required for safety functions |
| C | Brake test |
| D | Impact test for guards |
| E | Noise test code |
| F | Anti-kickback test |
| G | Test for anti-kickback devices of finger type |
| ZA | Relationship with Regulation (EU) 2023/1230 |
What are the key requirements of prEN ISO 19085-8?
prEN ISO 19085-8 sets out the safety measures that matter most for control systems, guarding, workpiece retention, ejection protection, laser use, noise, dust and user information. In practice, the standard is about preventing unexpected motion, keeping the operator away from moving tools, making sure the workpiece is supported and clamped, and verifying those measures by test.
Controls and safe stopping
Clause 4 requires the control system to meet the safety-related performance levels summarized in Annex B. This matters because the control logic itself is treated as a safety function, not just a convenience feature.
The machine needs emergency stop controls at the main control panel and at manual loading or unloading positions, and also near each hold-to-run control device where relevant. Clause 4 also requires safe stopping behavior, including retraction of processing units to their rest position, and for machines with a laser surface treating unit, cut-off of laser energy on safe stop.
Start functions are tightly interlocked. The cutterblock unit and multi blade unit may leave their rest position only when their rotating elements are running, and the laser surface treating unit may activate only when feed is running and the workpiece is detected under the unit. For a buyer or engineer, this means the machine design must prove that motion and process energy cannot start in the wrong condition.
Guarding, access prevention and anti-kickback
Clause 5 focuses on the moving parts and process hazards. Fixed guards must prevent access to running processing units, and where maintenance or setting access is needed, movable guards with interlocking are required. If rundown time is longer than 2 s, guard locking is also required.
The in-feed opening has its own trip device requirements, including stopping the feed belt and retracting processing units when actuated. The standard also sets geometry and force-related requirements for the trip device, which means the design must be checked against the machine opening and workpiece behavior, not only fitted as a general protection.
Ejection and kickback are handled with guard classes and anti-kickback devices. Cutterblock units and multi blade units have specific guard and anti-kickback provisions, while other processing units use class B guards for direct ejection protection. Annex D verifies guard impact resistance when the material or thickness is outside the listed cases, and Annexes F and G verify the anti-kickback devices.
Tool design, brake performance and workpiece support
Clause 5 also requires compliant cutterblocks and saw blades, and it requires loosening to be prevented during start-up, running, run-down and braking. The tool brake provisions are verified by the brake test in Annex C.
Workpiece support and clamping are not treated as secondary details. The machine needs a pressure roller or pressure pad before and after processing units, and the relevant clamping position must be interlocked with the processing unit position. Clause 5.10 also requires over-thickness protection and, for certain units, end stops to prevent contact or limit grooving depth.
Noise, dust, laser and ergonomics
Clause 6 requires noise emission measurement and declaration using Annex E. It also requires extraction for chips and dust from each processing unit, with the laser surface treating unit needing a dedicated extraction outlet. For the laser function, accessible parts must be laser class 1, and access to higher-class laser parts must be prevented with guards and interlocked energy cut-off.
The clause also addresses ergonomics: the machine must show workpiece thickness clearly, and manual loading or unloading machines have floor-height limits for the workpiece support. For a plant manager, this affects both safe use and operator fatigue.
Information for use
Clause 7 requires markings and instructions that support safe operation. The marking includes rotation-direction arrows, and laser-equipped machines need the accessible laser radiation warning symbol. The instruction handbook must cover foreseeable misuse, residual risks, inspection of anti-kickback devices, permitted workpiece length, permitted cutterblock types, maintenance restrictions for the laser unit, and connection to a dedicated extraction system.
What terms does prEN ISO 19085-8 define?
- Wide belt sanding machine - A machine that calibrates or sands flat workpieces with integrated feed and sanding belts positioned above or below the workpiece level.
- Surface treating machine - A machine that treats the surface of flat workpieces with an integrated feed and one of the listed brushing or texturing units, but no sanding belt unit.
- Cutterblock unit - A cylindrical processing unit with blades or inserts that cuts in parallel to the feed direction and against the feed.
- Multi blade unit - A grooving unit with saw blades mounted at preset distances on a shaft above the workpiece.
- Safety-related part of control system (SRP/CS) - The part of the control system that performs a safety function, such as interlocking or safe stopping.
- Performance level (PL) - The level used in the standard to state how reliable a safety function must be.
- Laser surface treating unit - A unit that finishes the workpiece surface by laser technology.
Who uses prEN ISO 19085-8?
prEN ISO 19085-8 is used by machine designers, manufacturers, suppliers and importers of woodworking machines. It is also relevant to quality managers, safety engineers, conformity assessment teams, regulators, market surveillance bodies and maintenance providers.
In practice, it helps anyone responsible for designing, buying, testing or approving wide belt sanding machines and surface treating machines, especially in woodworking, panel processing and surface finishing operations.
What changed in prEN ISO 19085-8 from the previous edition?
prEN ISO 19085-8 is the third edition and it cancels and replaces ISO 19085-8:2024. The changes listed for this edition are:
- the reference to ISO 19085-1:2026 is simplified and the explanation in the Introduction is aligned with ISO drafting rules

This document specifies the safety requirements and measures for wide belt sanding machines (defined
in 3.1) and for surface treating machines (defined in 3.2) capable of continuous production use, altogether
referred to as “machines”.
This document deals with all significant hazards, hazardous situations or hazardous events, listed in
Annex A, relevant to the machines when used as intended and under conditions of misuse which are
reasonably foreseeable, as well as when transported, assembled, adjusted, maintened, dismantling, disabled
and scrapped.
The machines are designed to process workpieces with flat surface and even thickness, in shape of panels or
beams or frames, consisting of:
— solid wood;
— material with similar physical characteristics to wood (see ISO 19085-1:2021, 3.2);
— gypsum boards, gypsum bounded fibreboards;
— composite materials with core consisting of, e.g. polyurethane or mineral material;
— rock wool and glass wool;
— polymer-matrix composite materials and reinforced thermoplastic, thermoset and elastomeric materials;
