(10) Keys for the column "Special packing provisions": Material compatibility (for gases see ISO 11114-1:1997 and ISO 11114-2:2000) a: Aluminium alloy pressure receptacles are not authorized. b: Copper valves shall not be used. c: Metal parts in contact with the contents shall not contain more than 65% copper. d: When steel pressure receptacles are used, only those resistant to hydrogen embrittlement shall be authorized. Requirements for toxic substances with an LC50 less than or equal to 200 ml/m3 (ppm) k: Valve outlets shall be fitted with pressure retaining gas-tight plugs or caps having threads that match those of the valve outlets and made of material not liable to attack by the contents of the pressure receptacle. Each cylinder within a bundle shall be fitted with an individual valve that shall be closed during carriage. After filling, the manifold shall be evacuated, purged and plugged. Bundles containing UN 1045 Fluorine, compressed, may be constructed with isolation valves on groups of cylinders not exceeding 150 litres total water capacity instead of isolation valves on every cylinder. Cylinders and individual cylinders within a bundle shall have a test pressure greater than or equal to 200 bar and a minimum wall thickness of 3.5 mm for aluminium alloy or 2 mm for steel. Individual cylinders not complying with this requirement shall be carried in a rigid outer packaging that will adequately protect the cylinder and its fittings and meeting the packing group I performance level. Pressure drums shall have a minimum wall thickness as specified by the competent authority. Pressure receptacles shall not be fitted with a pressure relief device. Cylinders and individual cylinders in a bundle shall be limited to a maximum water capacity of 85 litres. Each valve shall be capable of withstanding the test pressure of the pressure receptacle and be connected directly to the pressure receptacle by either a taper thread or other means which meets the requirements of ISO 10692-2:2001. Each valve shall either be of the packless type with non-perforated diaphragm, or be of a type which prevents leakage through or past the packing. Carriage in capsules is not allowed. Each pressure receptacle shall be tested for leakage after filling. (Cont'd on next page) Copyright © United Nations, 2010. All rights reserved - 109 - P200 PACKING INSTRUCTION (cont'd) P200 Gas specific provisions l: UN No. 1040 ethylene oxide may also be packed in hermetically sealed glass or metal inner packagings suitably cushioned in fibreboard, wooden or metal boxes meeting the packing group I performance level. The maximum quantity permitted in any glass inner packaging is 30 g, and the maximum quantity permitted in any metal inner packaging is 200 g. After filling, each inner packaging shall be determined to be leak-tight by placing the inner packaging in a hot water bath at a temperature, and for a period of time, sufficient to ensure that an internal pressure equal to the vapour pressure of ethylene oxide at 55 °C is achieved. The maximum net mass in any outer packaging shall not exceed 2.5 kg. m: Pressure receptacles shall be filled to a working pressure not exceeding 5 bar. n: Cylinders and individual cylinders in a bundle shall contain not more than 5 kg of the gas. When bundles containing UN 1045 Fluorine, compressed are divided into groups of cylinders in accordance with special packing provision "k" each group shall contain not more than 5 kg of the gas. o: In no case shall the working pressure or filling ratio shown in the tables be exceeded. p: For UN No. 1001 acetylene, dissolved, and UN No. 3374 acetylene, solvent free: cylinders shall be filled with a homogeneous monolithic porous material; the working pressure and the quantity of acetylene shall not exceed the values prescribed in the approval or in ISO 3807-1:2000 or ISO 3807- 2:2000, as applicable. For UN No. 1001 acetylene, dissolved: cylinders shall contain a quantity of acetone or suitable solvent as specified in the approval (see ISO 3807-1:2000 or ISO 3807-2:2000, as applicable); cylinders fitted with pressure relief devices or manifolded together shall be carried vertically. Alternatively, for UN No. 1001 acetylene, dissolved: cylinders which are not UN pressure receptacles may be filled with a non monolithic porous material; the working pressure, the quantity of acetylene and the quantity of solvent shall not exceed the values prescribed in the approval. The maximum test period for periodic inspection of the cylinders shall not exceed five years. A test pressure of 52 bar shall be applied only to cylinders conforming to ISO 3807-2:2000. q: Valve outlets of pressure receptacles for pyrophoric gases or flammable mixtures of gases containing more than 1% of pyrophoric compounds shall be fitted with gas-tight plugs or caps which shall be made of material not liable to attack by the contents of the pressure receptacle. When these pressure receptacles are manifolded in a bundle, each of the pressure receptacles shall be fitted with an individual valve that shall be closed during carriage, and the outlet of the manifold valve shall be fitted with a pressure retaining gas-tight plug or cap. Gas-tight plugs or caps shall have threads that match those of the valve outlets. Carriage in capsules is not allowed. r: The filling ratio of this gas shall be limited such that, if complete decomposition occurs, the pressure does not exceed two thirds of the test pressure of the pressure receptacle. ra: This gas may also be packed in capsules under the following conditions: (a) The mass of gas shall not exceed 150 g per capsule; (b) The capsules shall be free from faults liable to impair the strength; (c) The leakproofness of the closure shall be ensured by an additional device (cap, crown, seal, binding, etc.) capable of preventing any leakage of the closure during carriage; (d) The capsules shall be placed in an outer packaging of sufficient strength. A package shall not weigh more than 75 kg. (Cont'd on next page) Copyright © United Nations, 2010. All rights reserved - 110 - P200 PACKING INSTRUCTION (cont'd) P200 s: Aluminium alloy pressure receptacles shall be: - Equipped only with brass or stainless steel valves; and - Cleaned for hydrocarbons contamination and not contaminated with oil. UN pressure receptacles shall be cleaned in accordance with ISO 11621:1997. ta: Other criteria may be used for filling of welded steel cylinders intended for the carriage of substances of UN No. 1965: (a) with the agreement of the competent authorities of the countries where the carriage is carried out; and (b) in compliance with the provisions of a national code or standard recognised by the competent authorities. When the criteria for filling are different from those in P200(5), the transport document shall include the statement "Carriage in accordance with packing instruction P200, special packing provision ta" and the indication of the reference temperature used for the calculation of the filling ratio. Periodic inspection u: The interval between periodic tests may be extended to 10 years for aluminium alloy pressure receptacles. This derogation may only be applied to UN pressure receptacles when the alloy of the pressure receptacle has been subjected to stress corrosion testing as specified in ISO 7866:1999. v:
