Machinery   -   Machinery Safety Testing IEC Standards

IEC 60204: Ed 2.1 2009
We provide onsite testing for IEC 60204  provides requirements and recommendations relating to the electrical equipment of machines so as to promote:

– safety of persons and property;

– consistency of control response;

– ease of maintenance.

High performance is not to be obtained at the expense of the essential factors mentioned above. An example of a possible application of these requirements is a group of machines used in the production of discrete parts where a failure in such production machines or manufacturing systems or cells can have serious economic consequences.

IEC 60204-11:2000 This  part  of   IEC 60204 provides  requir ements  and  recommendations   relating  to  the highvoltage
electrical equipment  (HV equipment)  of  machines   together with  its  associated  low voltage electrical equipment (LV equipment) 

IEC 60204-33:2009 This standard  has been created to reflect the unique needs of electrical safety within the semiconductor manufacturing environment. This includes the specialized clean room environment in which semiconductors are fabricated as well as the specialized nature of the semiconductor fabrication equipment itself. IEC 60204-33 ensures a level of safety consistent with IEC 60204-1 while still permitting the flexibility needed in the design and operation of semiconductor fabrication equipment. It has been drafted to satisfy the electrical safety needs of the semiconductor industry.

IEC 60204-32:2008 This part of IEC 60204 provides requirements and recommendations relating to the electrical equipment of hoisting machines

IEC 61310-1:2007 Requirements for visual, acoustic and tactile signals: 

 It  is  via  the human- machine  interface  that  the  operator   interacts  with  the machinery  or process  in an open- loop  system.  This  interface consists of  actuators ,  by means  of  which  the opera tor initiates  actions ,and  indicating devices, through which  the operator   receives   information. In many applications, the information  is represented by a signal  which is encoded   by a distinct set of rules and the operator  has then to interpret the signal  according to these rules. Different types of coding such as colour, shape or time are  used  as appropriate to the demands of the task  of the operator.

The  reasons for using codes are: 
– to permit the spatial separation of the machinery  from  centralized control stations;
– to increase the perceptible amount of information given by an indicating device,for e.g, per display area unit, per unit of time;
– to decrease the mental  work - load of an operator and/or exposed persons .

IEC 61310-3:2007 Requirements for the location and operation of actuators

This  part of  IEC 61310 specifies safety-related requirements  for  actuators, operated by  the hand or by other  parts of  the human body,  at the human-machine  interface.It gives general requirements for 

–  the standard direction of  movement  for  actuators;

– the arrangement of an actuator in relation to other actuators;

–  the correlation between an action and  its  final effects.

It  is  based on IEC 60447 but  is  also  applicable  to non-electrotechnical  technologies such as  mechanical and  fluid-powered systems.It covers single actuators as well as groups of actuators forming part of an assembly.


IEC 61310-2:2007 Requirements for marking
This  part of IEC 61310 specifies requirements for the marking of machinery. It gives general rules on marking for identification of machinery, for safe use related to mechanical and electrical hazards, and for the avoidance of hazards arising from incorrect connections.  


IEC 60073 6th Ed.  Basic and safety principles for man-machineinterface, marking and identification –Coding principles for indicators and actuators
Indicator  for  the  representation of conditions, and actuating devices to enable intervention under  normal and fault  conditions, are essential to this purpose.The  information presented should meet the needs of the users for the monitoring and control tasks which they are required to perform, for example, in extensive industrial processes.Safety and ergonomic aspects should also be  taken into account. The use of only a single means of coding is often insufficient to ensure unambiguous representation of information. Apart from an unambiguous marking of  the indicating and actuating devices ,  there is a requir ement   for  a clear  and consistent system of coding. 

IEC 61511-1 Ed 1Functional safety – Safety instrumented systems for the process industry sector 
Safety instrumented systems have been used for many years to perform safety instrumented functions in the process industries. If instrumentation is to be effectively used for safety instrumented functions, it is essential that this instrumentation achieves certain minimum standards and performance levels. This  standard addresses the application of safety instrumented systems for   the process  industries.It also  requires a process hazard and risk assessment to be carried out to enable the specification for safety instrumented systems to be derived.
Other safety systems are only considered so  that  their contribution can be taken into account when considering  the performance  requirements for the safety  instrumented systems. The safety instrumented system includes all components and subsystems necessary to carry out the safety instrumented function from sensor(s) to final element(s).  This  standard has two concepts  which are  fundamental to its application;safety lifecycle and safety  integrity  levels.


IEC 61496-1 Ed 2.1Safety of machinery – Electro-sensitive protective equipment –
An elec tro-sensitive protective equipment (ESPE) is applied to machinery presenting a riskof personal injury. It provides protection by causing the machine to revert to a safe condition before a person can be  placed  in a hazardous situation. 
This part of IEC 61496 provides general design and performance requirements of ESPEs for use over a broad range of applications. Essential features of equipment meeting the requirements of this standard are the appropriate level of safety-related performance provided and the built-in periodic functional checks/self-checks that are specified to ensure that this level of performance is maintained. 

IEC 61496-2 Particular requirements for equipment using active opto-electronic protective  devices (AOPDs)  
IEC 61496-3 Particular requirements for Active Opto-electronic Protective Devices responsive to Diffuse Reflection (AOPDDR)
IEC 61496-4 Particular requirements for equipment using  vision based protective devices (VBPD) 


IEC 62006 Acceptance tests of small hydroelectric installations
This International Standard defines the test, the measuring methods and the contractual guarantee conditions for field acceptance tests of the generating machinery in small hydroelectric  power  installations.  It applies to  installations containing  impulse or reaction turbines with unit power up to about 15 MW and reference diameter of about 3 m. The driven generator can be of synchronous or asynchronous type.
