Project need:

This proposed New Standard is being developed at the request of industry and government. It will provide the regulators and industry with comprehensive requirements for the subject equipment. This will meet the strategic needs of the following key interests: identify as applicable how industry, regulators, consumers, government or others will benefit by a) ensuring that the latest technology/safety features are used by manufacturers and available for users; and b) addressing needs of regulators by providing requirements for the evaluation and approval of equipment.
