JUSTIFICATION OF NEW CLASSES OR TYPES OF PRACTICES CONSUMER PRODUCTS

Any undertaking intending to manufacture or import into Malta products for which the intended use is likely to lead to a new class or type shall provide the Commission with all relevant information, as to the:

intended use of the product, technical characteristics of the product;

in the case of products containing radioactive substances, information as to fixation;

dose rates at relevant distances for the use of the product, including dose distance of 10cm from any accessible surface;

expected doses to regular users of the product.

The Commission shall examine that information and in particular whether:

the performance of the consumer product justifies its intended use;

the design is adequate in order to minimize exposures in normal use and the consequences of misuse or accidental exposures, or whether there should imposed on the technical and physical characteristics of the product;

the product is adequately designed to meet the exemption criteria, and, applicable, is of an approved type and does not necessitate specific precautions for no longer in use;

the product is appropriately labelled and suitable documentation is provided consumer with instructions for proper use and disposal. FOURTH SCHEDULE Amended by: L.N. 184 of 2020. (Regulation 23)
