Agitators for use in reaction vessels or reactors specified in 2B350.a.; where all surfaces that come in direct contact with the fluid(s) being processed or contained are made from the following materials: 1. Stainless steels with more than or equal to 10,5 % chromium and less than or equal to 1,2 % carbon; c. Storage tanks, containers or receivers with a total internal (geometric) volume greater than 0,1 m 3 (100 litres) where all surfaces that come in direct contact with the fluid(s) being processed or contained are made from the following materials: 1. Stainless steels with more than or equal to 10,5 % chromium and less than or equal to 1,2 % carbon; d. Heat exchangers or condensers with a heat transfer surface area greater than 0,05 m 2 , and less than 30 m 2 ; and tubes, plates, coils or blocks (cores) designed for such heat exchangers or condensers, where all surfaces that come in direct contact with the fluid(s) being processed are made from the following materials: 1. Stainless steels with more than or equal to 10,5 % chromium and less than or equal to 1,2 % carbon; Technical Note: The materials used for gaskets and seals and other implementation of sealing functions do not determine the control status of the heat exchanger. e. Distillation or absorption columns of internal diameter greater than 0,1 m; where all surfaces that come in direct contact with the fluid(s) being processed are made from the following materials: 1. Stainless steels with more than or equal to 10,5 % chromium and less than or equal to 1,2 % carbon; f. Valves with ‘nominal sizes’ greater than 10 mm and casings (valve bodies) designed for such valves where all surfaces that come in direct contact with the fluid(s) being processed or contained are made from the following materials: 1. Stainless steels with more than or equal to 10,5 % chromium and less than or equal to 1,2 % carbon; Technical Note: 1. The materials used for gaskets and seals and other implementation of sealing functions do not determine the control status of the valve. 2. The ‘nominal size’ is defined as the smaller of the inlet and outlet diameters. g. Multiple-seal and seal-less pumps, with manufacturer’s specified maximum flow-rate greater than 0,6 m 3 /hour, in which all surfaces that come in direct contact with the chemical(s) being processed are made from the following materials: 1. Stainless steels with more than or equal to 10,5 % chromium and less than or equal to 1,2 % carbon. h. Vacuum pumps with a manufacturer’s specified maximum flow-rate greater than 1 m 3 /h (under standard temperature (273 K (0 °C)) 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 chemicals being processed are made from any of the following materials: 1. ‘Alloys’ with more than 25 % nickel and 20 % chromium by weight; 2. Ceramics; 3. ‘Ferrosilicon’; 4. Fluoropolymers (polymeric or elastomeric materials with more than 35 % fluorine by weight); 5. Glass (including vitrified or enamelled coatings or glass lining); 6. Graphite or ‘carbon graphite’; 7. Nickel or ‘alloys’ with more than 40 % nickel by weight; 8. Stainless steel with 20 % nickel and 19 % chromium or more by weight; 9. Tantalum or tantalum ‘alloys’; 10. Titanium or titanium ‘alloys’; 11. Zirconium or zirconium ‘alloys’; or 12. Niobium (columbium) or niobium ‘alloys’. Technical Notes: 1. The materials used for diaphragms or gaskets and seals and other implementation of sealing functions do not determine the status of control of the pump. 2. ‘Carbon graphite’ is a composition consisting of amorphous carbon and graphite, in which the graphite content is 8 % or more by weight. 3. ‘Ferrosilicons’ are silicon iron alloys with more than 8 % silicon by weight or more. For the listed materials in the above entries, the term ‘alloy’ 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.
