Ta mednarodni standard določa varnostne zahteve in ukrepe za osebe, ki se ukvarjajo z načrtovanjem, izgradnjo ter dobavo (vključno z namestitvijo, postavitvijo, vzdrževanjem in popravilom) strojev, kot je opredeljeno v točki 3 tega standarda, ki so primarno namenjeni za rezanje hladnih kovin (železnih in neželeznih) ali materiala, ki je delno sestavljen iz hladnih kovin, z orodjem za žaganje.
Ta mednarodni standard upošteva predvideno uporabo, pričakovano nepravilno uporabo, postavitev stroja in namestitev rezil, vzdrževanje in čiščenje ter njihove učinke na varnost upravljavcev in drugih izpostavljenih oseb. Predvideva dostop do stroja iz vseh smeri na ravni tal in obravnava tako običajno delovanje kot nepričakovan ali nenameren zagon.
Ta mednarodni standard zajema večje nevarnosti iz točke 4 in se uporablja tudi za pomožne naprave (npr. opremo za ravnanje z obdelovanci in čipirane transporterje), ki so sestavni del stroja. Kadar te naprave niso sestavni del stroja, mora načrtovalec, proizvajalec ali dobavitelj, ki namesti opremo, upoštevati njihovo predvideno uporabo in vzpostaviti pogoje za varno povezavo teh naprav s strojem.
Ta standard se uporablja predvsem za stroje za žaganje (kovin), ki so bili izdelani po tem, ko je CEN objavil ta standard.

Overview

EN ISO 16093:2017 (ISO 16093:2017) - "Machine tools - Safety - Sawing machines for cold metal" - specifies safety requirements for sawing machines whose primary intended use is sawing cold metal (ferrous and non‑ferrous). The standard addresses all significant hazards, hazardous situations and events reasonably foreseeable by the manufacturer (see Clause 4) and applies to (metal) sawing machines manufactured after the document’s publication. It is aligned with the EU Machinery Directive (2006/42/EC) and supersedes EN 13898:2003+A1:2009.

Key Topics and Technical Requirements

• Scope and definitions: Types of sawing machines covered are defined (Clause 3); scope and limits of applicability are in Clause 1 and Clause 4.
• Risk-based safety requirements (Clause 5): Guarding, modes of operation, control system requirements, and type‑specific safeguards for:
  • Band‑sawing machines
  • Circular sawing machines
  • Hack‑sawing machines (horizontal‑pivot type)
• Mechanical hazards: Power transmission elements, workholding and clamping devices, loading/unloading systems, swarf/chip containment and preventive maintenance.
• Electrical, thermal and ergonomic hazards: Requirements to reduce electrical risks, burns, unhealthy postures, repetitive strain and poor control layout.
• Noise and vibration: Addresses noise hazards and includes normative annexes for noise measurement (Annex A, B) - note it does not provide a complete noise test code (planned for future revision).
• Material hazards: Handling of fluids, gases, mists, fumes and dusts; metalworking fluid hygiene; swarf cleanability.
• Unexpected start/overrun and verification: Measures against unexpected starts, control failures, energy restoration and verification/testing of safety measures.
• Information for use (Clause 6): Markings, instruction handbook requirements and noise declaration.
• Supporting annexes: Normative and informative annexes (noise measurement, test conditions, example guards, performance level examples, bibliography).

Practical Applications and Who Uses It

• Machine manufacturers use ISO 16093:2017 to design and build safe sawing machines and to achieve a presumption of conformity with EU Machinery Directive requirements where applicable.
• Safety engineers and compliance officers apply the standard for risk assessment, guard design, and control system validation.
• Plant managers and maintenance teams use the guidance for installation, maintenance planning, preventive maintenance and operator information.
• Notified bodies and conformity assessment organizations reference the standard for equipment evaluation and regulatory compliance.

Related Standards and Notes

• Supersedes: EN 13898:2003+A1:2009.
• Relationship to EU Directive 2006/42/EC: Annex ZA maps the standard’s clauses to essential requirements; compliance gives a presumption of conformity when the standard is cited in the Official Journal.
• Limitations: The standard does not include full noise test code nor fire/explosion requirements (these are intended to be addressed in future revisions).

5 Safety requirements and/or protective measures
5.1 General requirements
Sawing machines shall comply with the safety requirements and/or protective/risk reduction measures
of this clause. In addition, the machine shall be designed according to the principles of ISO 12100 for
relevant but not significant hazards which are not dealt with by this document.
ISO 16093:2017(E)
For guidance on risk reduction by means of design, see ISO 12100:2010, Clause 4; and for safeguarding
measures, see ISO 12100:2010, Clause 5.
5.1.1 Guard requirements for all types of sawing machines
5.1.1.1 General
Guards shall be in accordance with ISO 14120. The fixing systems of fixed guards shall remain attached
to the guards or to the machinery when the guards are removed.
5.1.1.2 Height and position
Where guards are floor-mounted (e.g. perimeter fencing), they shall be fixed securely and have a
minimum height of 1,4 m. The distance from the hazard zone shall be in accordance with ISO 13857:2008,
Table 2. Any opening between the bottom of the guard and the floor shall not exceed 200 mm (see
ISO 11161:2007, 8.5.2).
5.1.1.3 Guarding of drives
Access to mechanical power transmission drives (e.g. chains and sprockets, gears, lead screws, feed
