(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 gas tight plugs or caps which shall be 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. 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. 2006/128. szám Each valve shall have a taper threaded connection directly to the pressure receptacle and be capable of withstanding the test pressure of the pressure receptacle. 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. 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 total quantity 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: A pressure receptacle 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 mass; 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 mass; 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: The valves 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 manifold outlet valve shall be fitted with a gas-tight plug or cap. Carriage in capsules is not allowed. r: Allowed for carriage 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. 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: (Reserved) 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. 2006/128. szám v: The interval between inspections for steel cylinders may be extended to 15 years: (a) with the agreement of the competent authority (authorities) of the country (countries) where the periodic inspection and the carriage take place; and (b) in accordance with the requirements of a technical code or a standard recognised by the competent authority, or standard EN 1440:1996 "Transportable refillable welded cylinders for liquefied petroleum gas (LPG) – Periodic requalification". Requirements for N.O.S. entries and for mixtures z: The construction materials of the pressure receptacles and their accessories shall be compatible with the contents and shall not react to form harmful or dangerous compounds therewith. The test pressure and filling ratio shall be calculated in accordance with the relevant requirements of (5). Unless otherwise specified in the tables of this packing instruction, toxic substances with an LC50 less than or equal to 200 ml/m3 shall not be carried in tubes, pressure drums or MEGCs and shall meet the requirements of special packing provision "k". For pressure receptacles containing pyrophoric gases or flammable mixtures of gases containing more than 1% pyrophoric compounds, the requirements of special packing provision "q" shall be met. The necessary steps shall be taken to prevent dangerous reactions (i.e. polymerisation or decomposition) during carriage. If necessary, stabilisation or addition of an inhibitor shall be required. Mixtures containing UN No. 1911 diborane, shall be filled to a pressure such that, if complete decomposition of the diborane occurs, two thirds of the test pressure of the pressure receptacle shall not be exceeded. Requirements for substances not in Class 2 ab: Pressure receptacles shall satisfy the following conditions: (i) The pressure test shall include an inspection of the inside of the pressure receptacles and check of accessories; (ii) In addition resistance to corrosion shall be checked every two years by means of suitable instruments (e.g. ultrasound) and the condition of the accessories verified; (iii) Wall thickness shall not be less than 3 mm. ac: Tests and inspections shall be carried out under the supervision of an expert approved by the competent authority. ad: Pressure receptacles shall satisfy the following conditions: (i) Pressure receptacles shall be designed for a design pressure of not less than 2.1 MPa (21 bar) (gauge pressure); (ii) In addition to the marks for refillable receptacles, the pressure receptacles shall bear the following particulars in clearly legible and durable characters: – The UN number and the proper shipping name of the substance according to 3.1.2; – The maximum permitted mass when filled and the tare of the pressure receptacle, including accessories fitted during filling, or the gross mass.
