FOREWOR1)

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by PlasticsSect ional Comtn it tee had been approved by the Petroleum Coal and Related Products Division Council.

Polycarbonatc linds wide use in food contact and health care applications. Some of the most important andknown applications of polycarbonate in this area are infant feeding bottles, drinking water containers, micro-ovenable food containers, blood oxygenator, dialyzer, tubes, intravenous stopcocks, etc. High molecular weight

polycarbonatc is inert and essentially insoluble in the compounds of food, water or body fluid with which itcomes in contact in the above applications and in itself does not pose any toxic hazard. It is, therefore, possiblethat some transfer will occur of polymer additives, adventitious impurities such as monomers. residual catalystsand solvents and low molecular weight polymer fractions from bulk of polycarbonate into the food, water orbody fluid \vitll consequent toxic hazard to the user. The occurrence of acute toxicity due to polycarbonate in

contact with food, water or body fluid is most unlikely, since only trace quantities of potentially toxic materialsare likely to migrate. However, the accumulation of these potentially toxic materials with time may lead tohazards which may be serious.

Polycarbonate resins are considered safe for use as articles or components of articles intended for use in producing,manufacturing, packing, processing, preparing, treating, packaging, transporting or holding food in accordancewith US FDA Regulations 21 CFR 177, 1580 and of the Regulations of several other countries like Germany.

This standard is intended to be used with series of Indian Standards on plastics for food contact applicationswhich are given in Annex A.

It is emphasized that these standards need to be used in combination to provide a system of control to themanufacturers and suppliers as well as the processors and users of polycarbonate material to derive maximum

benefits. Besides, it may also serve as basis for official agencies to frame suitable legislation to ensure effectivesafeguards for the safety and health of consumers where polycarbonate in food contact and related applicationsare concerned.

The list of additives prescribed in the current positive list are based on the information available in the draftsynoptic documerlt-5 on plastic materials and articles intended to come into contact with foodstuffs issued bycommission of European Communities and 182 Notification-Federal Public Health Gazette 32,211 (1989) ofGermany,

The composition of the Committee responsible for formulation of this standard is given in Annex B.

Review of Indian Standards

Amendments are issued to standards as the need arises on the basis of comments. Standards are also reviewedperiodically; a standard along with amendments is reaffirmed when such review indicates that no changes areneeded; if the review indicates that changes are needed, it is taken up for revision. Users of Indian Standards

should ascertain that they are in possession of the latest amendments or edition by referring to the latest issueof ‘BIS Handbook’ and’ Standards: Monthly Additions’.
