Participation in standardisation committees adds important knowledge about electrical safety
One of the main purposes of safety standards is to implement the requirements for safety in market requirements, e.g. EU directives. The requirements ensure that the risks of damage and injury to people, animals, environment, and property are kept down to an acceptable level.
Professional experts from our electrical safety group participate in various different national standardisation committees:
S608 (IEC TC 108)
Safety of electronic equipment within the field of audio/video, information technology and communication technology.
IEC TC108 develops the IEC 62368 series, which will replace EN 60950 and EN 60065 in the EU from 20 June 2019 (there is some uncertainty as to whether this date will be final).
S562 (IEC TC 62)
Develops the IEC 60601 series for Medical electrical equipment.
IEC TC 66
There is currently no national standardisation committee for IEC TC 66. We therefore keep ourselves up to date by receiving material from the meetings in IEC TC 66. IEC TC 66 develops the IEC 61010 series, Safety requirements for electrical equipment for measurement, control, and laboratory use.
Why do we participate in these standardisation groups?
There are various reasons why we participate in these standardisation groups:
At the forefront of developments
One important reason for participating is that it enables us to be at the forefront of the development of safety standards. Participation in meetings, minute taking, drafts of standards, working papers, comments from the other members etc. means that it is relatively easy for us to keep up-to-date with the objectives, thoughts, and plans that exist for the individual standards. This gives us ample opportunity to predict how the individual standards will look and to arrange our test services accordingly, so they are ready for our customers when they need them.
The national committees are the national mouthpieces, through which we can comment and propose changes to the standards. They give us a certain influence in forthcoming standards, e.g. that the Danish deviations will be respected.
Interpretation of requirements
The discussions during meetings and access to the written material from these meetings lead to adjustments to the interpretation of the individual requirements in the standards. The individual requirements are not always easy to interpret in the spirit that lies behind the wording. Clearly it is important for the manufacturer to design its product according to the correct interpretation, and it is just as important that we do not approve or reject a product on the basis of incorrect requirements.
Participation in standardisation work provides us with a network of other experts, which we call upon to clarify areas where there is some uncertainty or to draw each other’s attention to areas that need bringing into play.
Exchange of experience
Feedback from other test laboratories, manufacturers, and authorities shows whether the standards can be used in practice. As a test laboratory we are testing these standards daily in practice, but the experience from the manufacturers contributes heavily towards that which is hard to implement, and for example what is tricky or meaningless to demand or insufficient in order to fulfil the purpose of the standard; namely, the purpose of minimising the risk of damages caused by electric and electronic equipment.
