European countries often adopt IEC standards to facilitate trade and ensure compatibility of electrical systems across borders. The wide acceptance of these standards in Europe helps manufacturers to comply with safety and performance regulations, making them integral to the European market. Additionally, many European directives and regulations explicitly reference IEC standards, further reaffirming their significance in the region.
