EN ISO 10218-2
EN ISO 10218-2
The Standard EN ISO 10218-2 was published in July 2011 by Technical Committee ISO/TC 184 in collaboration with Technical Committee CEN/TC 310. This is a technical standard of type C, regarding robots and robotic devices. The scope of the Standard is to specify the safety requirements for the integration of industrial robots and industrial robot system. The integration includes:  -    The design, manufacturing, installation, operation, maintenance and decommissioning of the industrial robot system or cell;  -    Necessary information for the design, manufacturing, instllation, operation, mai
EN ISO 12100
EN 12100
The main topic of EN 12100, which went into effect on November 2010, is Machinery Safety. With this expression, the Norm defines as follow: The ability of a machine to perform its intended function(s) during its life cycle where risk has been adequately reduced. So, the Risk Reduction, is the aim of the norm, which provide guidelines about how to obtain a safe machine or equipment. The process conducted for this purpose is called Risk Assessment. There are so two stages to carry out: Risk Assessment Risk Reduction The Risk Assessment itself is composed by several operations: Mach
EN ISO 13855
The EN ISO 13855:2010 Standard, published in May 2010, replaces the European Standard EN 999:1998+A1: 2008.  This is a technical standard type-B regarding the positioning of safeguards with respect to the approach speeds of parts of human body.    Safeguards considered on this Standards include:  -    Electro-sensitive protective equipment (Light curtains and Laser scanner) -    Pressure-sensitive protective equipment (Pressure-sensitive mats) -    Two-hand control devices -    Interlocking guards without guard locking The Standard specifies minimum distances from the hazards caused by the m
EN ISO 14120
EN ISO 14120
The EN ISO 14120 Standard, published in October 2015, replaces the European standard EN 953:1997+A1:2009.  This is a technical standard of type-B regarding guards.  Its purpose is to specify the general principles for design, construction and selection of guards provided to protect people from mechanical hazards. Guards determine a risk reduction both thanks to the protection against unexpected accesses and against the ejection of parts of substances. Guards could also provide protection against other hazards such as noise, fire and radiation. The Standard applies to guards for machinery. 
EN ISO 11161
Integrated Machinery System (IMS)
The Standard EN ISO 11161 was published in May 2007 by the Technical CommiTtee ISO/TC 199 in substitution of the first version 1994 and it is currently under revision. This is a standard of type B1 regarding a specific safety aspect: the safety of the integrated machinery system (IMS).  NOTE: at the moment the acronim IMS stands for Integrated Manufacturing System; The new edition of the standard will use the term Integrated Machinery System. The Standard specifies the safety requirements for the integration of machinery into a system. It gives recommendations and requirements fot inherentl
EN ISO 14119
Interlocking device associated with guards
The EN ISO 14119 standard, published in October 2013, replaces the European standard EN 1088:1995+A2 (July 2008 edition). This is a technical standard of type B2 regarding a particular protective system against hazard: interlocking devices. Its purpose is to specify the principles for design and selection of interlocking device and to provide measures to minimize defeat and bypass of the device. The Standard also provides: Requirements for the design and the installation of interlocking devices with and without guard locking; Additional requirements on guard locking devices if its appli
ISO 14118
Prevention of Unexpected Start Up
Keeping a machine in a stopped condition while persons are present in danger zones is one of the most important conditions of the safe use of machinery and hence, one of the major aims of the machine designer and machine user. In the past, the concepts of “operating machine” and “stopped machine” were generally unambiguous; a machine was operating when its movable elements or some of them were moving; stopped when its movable elements were at rest. Machine automation has made the relationship between “operating” and “moving” on one hand and “stopped” and “at rest” on the other hand, more
EN ISO 13849-1
Performance Level Estimation: EN 13849-1
The topic of EN 13849-1, introduced on October 2006, is the reliability of safety systems, replacing the previous EN 954-1. The field of application of EN 13849-1 is the Safety Related Parts of Control System (SRP/CS), defined by the norm as: Part of a control system that responds to safety-related input signals and generates safety-related output signals. In other words, it is the set of control components with safety function, having the following tasks: Identify hazardous situations (input/sensors) Elaborate a proper response (logic) Execute the elaborated response (output/actuator
ISO/TR 24119
The Fault Masking
ISO/TR 24119 is a Technical Report published for the first time in November 2015 with the title "Safety of machinery — Evaluation of fault masking serial connection of interlocking devices associated with guards with potential free contacts". Before this document was issued, it wasn't clear how many interlocks could be wired to one safety channel and how much was the Diagnostic Coverage of the Safety Subsystem (Input + Logic). When connecting several interlock to one safety channel a fault may be masked: the problem is therefore called Fault Masking. This Technical Report explains what t
EN ISO 13850
Emergency Stop Function: EN 13850
The Machinery Directive 2006/42/CE, about the safety stop function, states that: Machinery must be fitted with one or more emergency stop devices to enable actual or impending danger to be averted. The purpose of the Emergency Stop Function is to to stop the hazardous functions of machinery as quickly as possible, without creating any further risks. It is not always required the presence of an emergency stop device on a machine, in particular when: Machinery in which an emergency stop device would not lessen the risk, either because it would not reduce the stopping time or because it wo
EN 14122-4
Fixed ladders
The Standard EN ISO 14122-4 was published in Italy on October 2016, replaces the previous EN ISO 14122-4 of 2010 and is not applicable to machinery manufactured before the date of its publication. This part of ISO 14122 gives requirements for fixed ladders which are a part of a stationary machine, and to the non-powered adjustable parts (e.g. foldable, slidable) and movable parts of fixed ladder systems.. The new standard, thanks to the use of images, allows to have a clearer idea of what are the requirements to be observed.
EN ISO 13857
Safety Distances
The EN ISO 13857 standard, which was published in March 2008, replaces the previous EN 294: 1993 and EN 811: 1998 standards and it is currently under revision in its DIS version (Draft Internation Standard). This is a standard of type B1 regarding a specific safety aspect: the safety distances. Its purpose is to provide the safety requirements that the protective structures must have in order to prevent the achievement and contact of Hazard Zones in both industrial and non-industrial environments, for this reason also the situations of possible contacts for 3-years-old children are considere
