This widespread exposure is often missing if it is developed through a national position in the typically much smaller US TAG or Canadian National Committee. The evaluation process itself raises awareness of the standard and aids in its widespread implementation. Adopting an international standard helps develop a single worldwide market. Agreement to use a single standard can help everyone. Users will have available a global list of vendors that can be compared on price, quality, and delivery.
Manufacturers can provide a single design to a world market.
System designers and consultants have fewer issues when interfacing to the world's variety of existing infrastructures. The organizational structure, terms, definitions, and clauses of an IEC standard may be quite appropriate for use. The IEC encourages countries to adopt their standards, just as IEEE cooperates when IEC uses our documents as a base. The IEEE process can be used to identify problem areas in need of revision. Any vague or ambiguous clauses are more apt to be identified when a single standard has undergone widespread evaluation.
