1 Any of the following chemical manufacturing facilities, equipment and components, other than any thing which is specified in or by Dual-Use Code 2B350— a reaction vessels or reactors, with or without agitators, with total internal (geometric) volume greater than 0.1m 3 (100 litres) and less than 20m 3 (20,000 litres), provided that all surfaces that come in direct contact with the fluid being processed or contained is made from the relevant composition; b agitators for use in reaction vessels or reactors specified in paragraph (a), provided that all surfaces that come in direct contact with the fluid being processed or contained is made from the relevant composition; c storage tanks, containers or receivers with a total internal (geometric) volume greater than 0.1m 3 (100 litres) where all surfaces that come in direct contact with the chemical being processed or contained is made from the relevant composition; d heat exchangers or condensers with a heat transfer surface area greater than 0.05m 2, and less than 30m 2 and tubes, plates, coils or blocks (cores) designed for such heat exchangers or condensers, provided that all surfaces that come in direct contact with the fluid being processed is made from the relevant composition; e distillation or absorption columns of internal diameter greater than 0.1 metre, provided that all surfaces that come in direct contact with the fluid being processed is made from the relevant composition; f liquid distributors, vapour distributors or liquid collectors designed for distillation or absorption columns mentioned in sub-paragraph (e); g valves with a nominal size greater than 10mm and casings (valve bodies) designed for such valves, provided that all surfaces that come in direct contact with the fluid being processed or contained is made from the relevant composition; h multiple-seal and seal-less pumps, with manufacturer's specified maximum flow-rate greater than 0.6m 3 per hour, in which all surfaces that come in direct contact with the chemical being processed is made from any of the following materials— i ceramics; ii ferrosilicon; iii stainless steel with either— aa more than or equal to 10.5% chromium and less than or equal to 1.2% carbon, or bb 20% nickel and 19% chromium or more by weight; i casings (pump bodies), preformed casing liners, impellers, rotors or jet pump nozzles designed for pumps mentioned in paragraph (h)(i), (ii) and (iii)(bb); j vacuum pumps with a manufacturer's specified maximum flow-rate greater than 1m 3 per hour (under standard temperature (0 degree Celsius) and pressure (101.3 kPa) conditions), and casings (pump bodies) and preformed casing-liners, impellers, rotors and jet pump nozzles designed for such pumps, in which all surfaces that come into direct contact with the chemical being processed is made from any of the following materials— i alloys with more than 25% nickel and 20% chromium by weight; ii ceramics; iii ferrosilicon; iv fluoropolymers (polymeric or elastomeric materials with more than 35% fluorine by weight); v glass (including vitrified or enamelled coatings or glass lining); vi graphite or carbon graphite; vii nickel or alloys with more than 40% nickel by weight; viii stainless steel with 20% nickel and 19% chromium or more by weight; ix tantalum or tantalum alloys; x titanium or titanium alloys; xi zirconium or zirconium alloys; xii niobium (columbium) or niobium alloys. 2 For the purpose of sub-paragraph (1)— “alloys”, when not accompanied by a specific elemental concentration, is understood as identifying those alloys where the identified metal is present in a higher percentage by weight than any other element; “carbon graphite” means a composition consisting of amorphous carbon and graphite, in which the graphite content is 8% or more by weight; “ferrosilicon” means silicon iron alloys with 8% silicon or more by weight; “nominal size” means the smaller of the inlet and outlet diameters; “the relevant composition” means stainless steel with either— more than or equal to 10.5% chromium and less than or equal to 1.2% carbon, or 20% nickel and 19% chromium or more by weight; 3 For the purposes of sub-paragraph (1), the materials used for diaphragms, gaskets, seals and other implementation of sealing functions— a in the case of paragraph (d), do not determine the control status of the heat exchanger, b in the case of paragraph (g), do not determine the control status of the valve, and c in the case of paragraph (j), do not determine the control status of the pump.
