15、e for the storage and transportation of substances in liquid or solid form. 1.2 This standard also covers self-supporting plastics containers, of maximum nominal capacity 10 L, for reserve fuel for motor vehicles. 1.3 When dangerous substances intended for export are packed in self-supporting plasti

16、cs containers, cognizance shall be taken of the applicable regulations of the following organizations: a) International Civil Aviation Organization (ICAO) technical instructions for the safe transport of dangerous goods by air; b) International Maritime Organization (IMO) international maritime dang

32、iners Containers shall be of an effective plastics material. The colour of the material of a finished container shall be an acceptable match to the colour required. Additives such as fillers, plasticizers, anti-static agents, pigments and inhibitors that are used in the plastics formulation shall be

33、 compatible with the polymer and shall not deleteriously affect the commodity for which the container is intended. The plastics material of a finished container shall be compatible with the commodity contained and such compatibility shall be established by an organization acceptable to the regulator

34、y authorities. In the case of containers intended for dangerous goods, the relevant requirements of SANS 10229-1 shall apply and in cases where substances for human consumption are packed, cognizance shall be taken of the relevant national legislation (see foreword). Amdt 1 NOTE Test procedures to d

35、etermine the compatibility of plastics containers and commodities, and that may be acceptable to the regulatory authorities, are given in annex C. 4.2 Requirements for closures Plastics closures of a material different from that of the container shall comply with the requirements of 4.1. SANS 1176:2

36、010 Edition 3.1 6 5 Construction 5.1 Style A container shall be of one of the styles given in 5.1.1 and 5.1.2, as required. 5.1.1 Tight-head (fixed-end, non-removable head) style The body, top and bottom and the flange(s) for the closure(s) shall be integral, i.e. moulded in one piece or combined to

37、 form one piece. There shall be either one or two closures of internal diameter not exceeding 70 mm at the top end of the container. The number, types and internal diameters of the closures shall be as required. The closures shall be so designed that they will seal efficiently, and threaded closures

38、 shall be resistant to “cork creep“. NOTE Tight-head containers may also be of the non-invertible style (see 3.9). 5.1.2 Open-head (removable head) style The body and bottom shall be integral, i.e. moulded in one piece. The lid (top) and the flange(s) (if any) shall be moulded in one piece. The numb

39、er (but not more than two), types and internal diameters of additional closures shall be as required. The lid and the rim of the container shall be such as to provide a good matching fit and, when so required, the joint shall be provided with a gasket. The lid shall be secured in position by means o

40、f a suitable clamping or strapping device that ensures a tight fit. 5.2 Handles Handles, if required, shall be of the type and number required, shall be of adequate size, and of strength such as to enable the container to comply with the requirements of 6.10. 5.3 Shape and dimensions The shape and d

41、imensions of a container shall be as required and shall make provision for the appropriate ullage (see 5.4). 5.4 Capacity The nominal capacity of a container shall be as required, and shall preferably be one of the following: 5 L, 10 L, 20 L, 25 L, 50 L, 100 L or 220 L. The actual capacity (i.e. the

42、 brimful capacity less the quantity displaced by the closure) shall be such that a) in the case of containers for liquid commodities, the liquid in the container would not fill the container when heated to 55 C, and b) in the case of containers for solid commodities, it exceeds the nominal capacity

43、by at least 1,5%. 5.5 Mass The mass of a finished container shall not differ by more than 3% from the nominal mass agreed upon. SANS 1176:2010 Edition 3.1 7 5.6 Finish and workmanship The finish and workmanship shall be such as to be acceptable. Both the inside and the outside of a container shall b

44、e acceptably free from pits and flashing, and pigmentation shall be evenly distributed.
