Machine tools safety - Machining centres, milling machines, transfer machines - Part 1: Safety requirements (ISO 16090-1:2022, Corrected version 2023-10)
This document specifies the technical safety requirements and protective measures for the design, construction and supply (including installation and dismantling, with arrangements for transport and maintenance) of:
— milling machines (see 3.1.1), including machines capable of performing boring operations (see 3.1.2);
— machining centres; and
— transfer machines (see 3.1.3)
designed for continuous production use, which are intended to cut cold metal and other non-combustible cold materials, except wood or materials with physical characteristics similar to those of wood as defined in ISO 19085‑1 and glass, stone and engineered/agglomerated materials as defined in EN 14618.
This document covers the following machines (referred to as "machines" in this document):
a) manually, without numerical control, operated boring and milling machines (see 3.2.1, Group 1), e.g. knee and column type milling machines (see Figures C.1 and C.2);
b) manually, with limited numerical control, operated boring and milling machines (see 3.2.2, Group 2), e.g. profile and contouring milling machines (see Figures C.3 and C.4);
c) numerically controlled milling machines and machining centres (see 3.2.3, Group 3), e.g. automatic milling machines and milling centres, e.g. multi-spindle milling machines, gear-milling machines (see Figures C.5 to C.7);
d) transfer and special-purpose machines (see 3.2.4, Group 4), which are designed to process only pre-specified workpieces or limited range of similar workpieces by means of a predetermined sequence of machining operations and process parameters (see Figures C.8 to C.13).
e) machines fitted with the following devices/facilities, whose hazards have been dealt with:
— tool magazine(s);
— tool changer(s);
— workpiece handling mechanism(s);
— powered workpiece clamping mechanism(s);
— swarf/chip conveyor(s);

— additional equipment for grinding.
This document deals with all significant hazards, hazardous situations and events relevant to this type of machinery which can occur during transportation, assembly and installation, setting, operation, cleaning and maintenance, troubleshooting, dismantling or disabling according to ISO 12100, when the machinery is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This document presumes accessibility to the machine from all directions and specifies access conditions to operator positions. It also applies to workpiece transfer devices including transport devices for loading/unloading when they form an integral part of the machine.

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 ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 10,
Safety, in collaboration with the European Committee for Standardization (CEN) Technical Committee
CEN/TC 143, Machine tools — Safety, in accordance with the Agreement on technical cooperation
between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 16090-1:2017), which has been
technically revised.
The main changes are as follows:
— update and addition of safety functions in Annex J,
— revision of operating modes and change of designation from MSO (mode of safe operation) to MO
(mode of operation),
— former MSO 3 (optional special mode for manual intervention under restricted operating conditions),
in the current addition referred to as MO 3 (manual intervention under restricted operating
conditions), has been revised in a way, that the usage of an enabling device is necessary in any case,
i.e. dispensing of the enabling device is no longer possible.

ISO 16090-1:2022(E)
Introduction
This document is a type-C standard as stated in ISO 12100.
This document is of relevance, in particular for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organisations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the
other standards for machines that have been designed and built according to the requirements of this
type-C standard.
Machining centres, milling machines and transfer machines present a wide range of hazards. Protection
of operators and other persons from contact with moving cutting tools, especially when being rapidly
rotated in the spindle or being swung from a tool magazine to the spindle during power-operated tool
changing, or from contact with fast–moving workpieces, is of great importance.
When power-operated mechanisms are provided for workpiece transfer, they can also create hazardous
situations during loading/unloading and workpiece alignment, clamping or releasing of the workpiece.
The significant hazards covered by this document are those listed in Clause 4. The safety requirements
and/or protective measures to prevent or minimize those hazards identified in Table 1 and procedures
for verification of these requirements or measures are found in 5.17.
Figures D.1 to D.8 are examples only and are not intended to illustrate the only interpretation of the
text.

b) initiates and monitors the motor deceleration rate within set limits to stop the motor and initiates
the STO function when the motor speed is below a specified limit; or
c) initiates the motor deceleration and initiates the STO function after an application specific time
delay
