However, the indications listed in Annex III to this Directive shall be authorized if they meet the relevant criteria laid down in that Annex or, in the absence thereof, criteria laid down in national provisions and provided that they have been drawn up on the basis of physico-chemical analyses and, where necessary, pharmacological, physiological and clinical examinations carried out according to recognized scientific methods, in accordance with Section I, paragraph 2 of Annex I.

The investigation showed that the metallisation process consisting of the addition of metal, such as aluminium, by a vapour deposition process, does not alter the basic physical, technical and chemical characteristics of PET film.

As in the previous investigation, this investigation has shown that the tube or pipe fittings of iron or steel, produced in the countries concerned, sold domestically and/or exported to the Community have the same basic physical and chemical characteristics as the products sold in the Community by the applicant Community producers and are considered to be like products, within the meaning of Article 1(4) of the basic Regulation.

In a second phase, having regard to the extent of exposure of the product to the environment, and the available information about the physical/chemical, pharmacological and/or toxicological properties of the compound which has been obtained during the conduct of the other tests and trials required by this Directive, the investigator shall then consider whether further specific investigation of the effects of the product on particular eco-systems is necessary.

During the preliminary investigations it was found that there were black colorformers other than ODB-1 and ODB-2 which appeared to share the same basic chemical and physical characteristics and appeared to overlap in their use (namely coating paper for use as carbonless copy paper ('carbonless paper') or paper for thermal image applications ('thermal paper')).
