We greatly appreciate having been given permission by the following contributors to use their images in our Techline. All of the electrotechnology shown has been standardized by the IEC and many different and competing companies around the world, including the ones listed here, use IEC International Standards. The images represent some of the fields of technology for which the IEC prepares its International Standards, but should not be considered as representing the entire universe of IEC work. In fact, more than 14 000 companies from all around the world contribute to preparing IEC standards.
