Safety of machinery - Guards - General requirements for the design and construction of fixed and movable guards

Safety of machinery - Guards - General requirements for the design and construction of fixed and movable guards

This European Standard specifies general requirements for the design and construction of guards provided primarily to protect persons from mechanical hazards.
The standard applies primarily to machines which are manufactured after the date of issue of this standard.
Attention is drawn to the use of guards to minimise exposure to non-mechanical hazards.
The requirements are applicable if fixed and movable guards are used. The standard does not cover those parts of guards which actuate interlocking devices. These are covered in EN 1088.
This standard does not provide requirements for special systems relating specifically to mobility and ability to lift loads like rollover protective structures (ROPS) and falling-object protective structures (FOPS).

Safety of machinery - Safety distances to prevent hazard zones being reached by upper and lower limbs (ISO 13857:2019)
SIST EN ISO 13857:2020

This document establishes values for safety distances in both industrial and non-industrial environments to prevent machinery hazard zones being reached. The safety distances are appropriate for protective structures. It also gives information about distances to impede free access by the lower limbs (see Annex B).
This document covers people of 14 years and older (the 5th percentile stature of 14-year-olds is approximately 1 400 mm). In addition, for upper limbs only, it provides information for children older than 3 years (5th percentile stature of 3-year-olds is approximately 900 mm) where reaching through openings needs to be addressed.
NOTE 1  It is not practical to specify safety distances for all persons. Therefore, the values presented are intended to cover the 95th percentile of the population.
Data for preventing lower limb access for children is not considered.
The distances apply when sufficient risk reduction can be achieved by distance alone. Because safety distances depend on size, some people of extreme dimensions will still be able to reach hazard zones even when the requirements of this document are met.
Compliance with the requirements in this document will prevent access to the hazard zone. Nevertheless the user of this document is advised that it does not provide the required risk reduction for every hazard (e.g. hazards related to machine emissions such as ionizing radiation, heat sources, noise, dust).
The clauses covering lower limbs apply on their own only when access by the upper limbs to the same hazard zone is not foreseeable according to the risk assessment.
The safety distances are intended to protect those persons trying to reach hazard zones under the conditions specified (see 4.1.1).
NOTE 2  This document is not intended to provide measures against reaching a hazard zone by climbing over (see ISO 14120:2015, 5.18).

Safety of machinery - Two-hand control devices - Principles for design and selection (ISO 13851:2019)
SIST EN ISO 13851:2019

This document specifies the safety requirements of a two-hand control device (THCD) and the dependency of the output signal from the actuation by hand of the control actuating devices.
This document describes the main characteristics of THCDs for the achievement of safety and sets out combinations of functional characteristics for three types. It does not apply to devices intended to be used as enabling devices, as hold-to-run devices or as special control devices.
This document does not specify with which machines THCDs shall be used. It also does not specify which types of two-hand-control device shall be used for a specific application. Moreover, while guidance is given, it does not specify the required distance between the THCD and the danger zone (see 8.8).
This document provides requirements for design and guidance on the selection (based on a risk assessment) of THCDs including the prevention of defeat, the avoidance of faults and verification of compliance.
NOTE 1    A THCD only offers protection for the person using it.
NOTE 2    For specific machines, the suitability of a two-hand control as a suitable protective device can be defined in a type-C standard. If such a standard does not exist or is not appropriate, the risk assessment and determination of suitable protective measures is the responsibility of the manufacturer of the machine.
This document applies to all THCDs, independent of the energy used, including:
—          THCDs which are fully assembled for installation;
—          THCDs which are assembled by the machine manufacturer or integrator.
This document is not applicable to THCDs manufactured before the date of its publication.

Safety of machinery - Prevention of unexpected start-up (ISO 14118:2017)
SIST EN ISO 14118:2018

ISO 14118:2017 specifies requirements for designed-in means aimed at preventing unexpected machine start-up (see 3.2) to allow safe human interventions in danger zones (see Annex A).
ISO 14118:2017 applies to unexpected start-up from all types of energy source, i.e.:
-      power supply, e.g. electrical, hydraulic, pneumatic;
-      stored energy due to, e.g. gravity, compressed springs;
-      external influences, e.g. from wind.
ISO 14118:2017 does not specify performance levels or safety integrity levels for safety-related parts of control systems. While available means to prevent unexpected start-up are identified, this document does not specify the means for the prevention of unexpected machine start-up for specific machines.
NOTE       A type-C standard can define the required means for the prevention of harm arising from unexpected start-up. Otherwise, the requirements for a specific machine need to be determined by risk assessment outside the scope of this document.
