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 61496-3 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.
