Overview

prEN ISO 19085-10 / ISO/DIS 19085-10:2025 is a CEN/ISO draft safety standard for building site saws (contractor saws) - portable or displaceable woodworking machines designed to cut wood and materials of similar physical characteristics. It specifies safety requirements and protective measures for all significant hazards during normal use, reasonably foreseeable misuse, and life‑cycle phases such as transport, assembly, dismantling, disabling and scrapping. The standard covers machines with saw blade diameters between 350 mm and 500 mm and excludes hand‑held tools, machines for explosive atmospheres, and certain table saw variants (see Related Standards).

Key Topics

The document organizes technical safety requirements that manufacturers and safety professionals must address, including:

• Control systems and operator controls: reliability, start/stop modes, emergency stop, safe stops, manual reset, mode selection and speed‑change methods.
• Braking and run‑down: braking of tools, maximum run‑down time and brake release requirements.
• Mechanical protection and guards: fixed guards, interlocking movable guards, hold‑to‑run, two‑hand controls, enabling controls, and prevention of access to saw blade above and below the table.
• Tool and fixture safety: spindle locking, circular saw blade fixing, flange dimensions and measures to prevent tool break‑up and ejection.
• Anti‑kickback and chip ejection controls: guard materials, anti‑kickback devices, and workpiece retention.
• Work‑piece support and guides: rip fences, cross‑cut fences, tables and extension supports to reduce operator risk and improve cutting accuracy.
• Sensing and protective equipment: electro‑sensitive protection equipment (ESPE), pressure sensitive protection equipment (PSPE), standstill detection and speed monitoring.
• Other hazards: noise and dust emission, electrical safety, ergonomics, lighting, hydraulics/pneumatics, electromagnetic compatibility and maintenance access.

Applications

Who uses ISO 19085-10 and why:

• Manufacturers and designers - to design compliant building site saws and select safe components, braking systems and guards.
• Compliance and conformity bodies - to assess machines for CE marking and regulatory compliance.
• Safety engineers and risk assessors - to perform hazard analyses and specify mitigations for mobile saws used on construction sites.
• Procurement/specification authors - to write purchase specifications for contractor saws that meet recognized safety criteria.
• Contractors, site supervisors and maintenance staff - to understand safe operating, assembly, transport and maintenance practices.
• Test laboratories and inspectors - to verify performance of guards, braking, noise/dust emissions and safety controls.

Related Standards

• ISO 19085-1 (definition of displaceable machines)
• ISO 19085-9 (table saws; machines with blade tilt, multiple speeds, sliding table)
• ISO 12100 (general principles for risk assessment and risk reduction)
• IEC 62841-1 / IEC 62841-2-5 (hand‑held motor‑operated electric tools)

This standard is essential for anyone responsible for the safe design, manufacture, procurement or use of woodworking machines on construction sites and supports compliance with European and international machine safety expectations.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the

5.6 Prevention of access to hazardous moving parts
5.6.1 Access to the saw blade above the machine table
An automatically adjustable guard shall restrict access to the saw blade above the machine table. It shall
be fitted to the riving knife or to the machine separately from the riving knife. In the latter case, it shall be
mounted to the machine with a support not being in line with the riving knife (see Figure 1).
The saw blade guard shall be in accordance with the following requirements.
a) It shall be made of transparent material.
b) A front opening in the guard shall provide an unobstructed view of the saw blade and the cutting line to
a machine operator feeding the material to be cut. Position and size of the opening shall be such that the
operator does not need to assume an unnatural position, e.g. slouching or bend-over. The dimensions
of this opening shall be such that a test probe with the dimensions given in Annex K does not reach the
saw blade through this opening. Any other opening in the guard shall be in accordance with the safety
distance requirements of ISO 13857:2019.
c) In the area where the saw blade guard can come in contact with the rip fence in the lower position, the
maximum width of the saw blade guard shall not exceed 50 mm.
d) It shall rest on the table when the machine is not in use (see Figures 1 and 6). The pivots in the mounting
arrangement for the saw blade guard shall be designed in such a way that it is not possible to lock the
saw blade guard in an elevated position.
e) The lower inner edges of the sides of the saw blade guard shall be lined with a rib, made of plastic, light
alloy, wood or wood-based materials. This rib shall be a minimum 3 mm in width, and shall be designed
so as to prevent the saw blade teeth from cutting into the saw blade guard should the saw blade guard
be displaced from the line of cut (see Figure 3). If the rib is replaceable, the fixing arrangement shall be
such that it does not damage the saw blade, e.g. with brass screws.

f) It shall be capable of upward movement during work-piece feeding. The vertical force required to open
the saw blade guard, applied to measuring point A in Figure H.1, key 1, shall not exceed 8 N.
g) During work-piece feeding, the bottom of the saw blade guard shall rest on the work-piece (see Figure 6).
h) To avoid jamming of the work-piece during feeding, a riving knife mounted saw blade guard shall have
an end stop for its top position that prevents it from being raised higher than its assembly device on the
riving knife (see Figure 4).

i) A saw blade guard mounted separately from the riving knife shall be adjustable in height from the table
level up to a maximum height of 5 mm above the largest saw blade for which the machine is designed.
j) The mounting arrangement of the saw blade guard shall not be capable of being moved out of position
without the aid of a tool.
k) The in-feed end of the saw blade guard shall have a “lead-in”. If the saw unit is fitted with the maximum
saw blade and raised to the maximum height, the lead-in shall allow the saw blade guard to be raised by
a work-piece with a thickness of at least 60 % of the maximum cutting height for which the machine is
designed. This can be achieved by a slope with an angle α of not more than 45° (see Figure 5).
l) It shall pass the saw blade guard rigidity test in Annex H.
