1.7 Definitions

 For the purpose of this Code, unless expressly provided otherwise, the following definitions shall apply:

Angle of repose means the maximum slope angle of non-cohesive (i.e. free-flowing) granular material. It is measured as the angle between a horizontal plane and the cone slope of such material.

  Bulk Cargo Shipping Name (BCSN) identifies a bulk cargo during transport by sea. When a cargo is listed in this Code, the Bulk Cargo Shipping Name of the cargo is identified by capital letters in the individual schedules or in the index. When a cargo is dangerous goods as defined in the IMDG Code, as defined in regulation VII/1.1 of the SOLAS Convention, refer to 4.1.1.

  Bulk density means the weight of solids, air and water per unit volume. Bulk density is expressed in kilograms per cubic metre (kg/m3), in general. The void spaces in the cargo may be filled with air and water.

  Cargo space means any space in a ship designated for carriage of cargoes.

  Cargoes which may liquefy means cargoes which contain a certain proportion of fine particles and a certain amount of moisture. They may liquefy if shipped with a moisture content in excess of their transportable moisture limit.

  Cohesive material means materials other than non-cohesive materials.

  Competent authority means any national regulatory body or authority designated or otherwise recognized as such for any purpose in connection with this Code. The competent authority shall operate independently from the shipper.

  Concentrates means materials obtained from a natural ore by a process of enrichment or beneficiation by physical or chemical separation and removal of unwanted constituents.

  Consignment means a solid bulk cargo presented by a shipper for transport.

  Flow moisture point means the percentage moisture content (wet mass basis) at which a flow state develops under the prescribed method of test in a representative sample of the material (see paragraph 1 of appendix 2).

  Flow state means a state occurring when a mass of granular material is saturated with liquid to an extent that, under the influence of prevailing external forces such as vibration, impaction or ship's motion, it loses its internal shear strength and behaves as a liquid.

  GHS means the seventh revised edition of the Globally Harmonized System of Classification and Labelling of Chemicals, published by the United Nations as document ST/SG/AC.10/30/Rev.7.

  Group A consists of cargoes which may liquefy if shipped at a moisture content in excess of their transportable moisture limit.

  Group B consists of cargoes which possess a chemical hazard which could give rise to a dangerous situation on a ship.

  Group C consists of cargoes which are neither liable to liquefy (group A) nor to possess chemical hazards (group B).

  High-density solid bulk cargo means a solid bulk cargo with a stowage factor of 0.56 m3/t or less.

  IMDG Code means the International Maritime Dangerous Goods (IMDG) Code adopted by the Maritime Safety Committee of the Organization by resolution MSC.122(75), as may be amended by the Organization.

  Incompatible materials means materials that may react dangerously when mixed. They are subject to the segregation requirements of 9.3 and the schedules for individual cargoes classified in group B.

  International Ship and Port Facility Security (ISPS) Code means the International Code for the Security of Ships and of Port Facilities consisting of Part A (the provisions of which shall be treated as mandatory) and Part B (the provisions of which shall be treated as recommendatory), as adopted, on 12 December 2002, by resolution 2 of the Conference of Contracting Governments to the International Convention for the Safety of Life at Sea, 1974, as may be amended by the Organization.

  Manual of Tests and Criteria means the sixth revised edition of the United Nations publication entitled "Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria" (ST/SG/AC.10/11/ Rev.6/Amendment 1).

  Materials hazardous only in bulk (MHB) means materials which may possess chemical hazards when carried in bulk other than materials classified as dangerous goods in the IMDG Code.

  Moisture content means that portion of a representative sample consisting of water, ice or other liquid expressed as a percentage of the total wet mass of that sample.

  Moisture migration means the movement of moisture contained in a cargo by settling and consolidation of the cargo due to vibration and ship's motion. Water is progressively displaced, which may result in some portions or all of the cargo developing a flow state.

  Non-cohesive material means dry materials that readily shift due to sliding during transport, as listed in appendix 3, paragraph 1, “Properties of dry bulk cargoes”.

  Potential sources of ignition means, but is not limited to, open fires, machinery exhausts, galley uptakes, electrical outlets and electrical equipment unless they are of certified safe typefootnote.

  Representative test sample means a sample of sufficient quantity for the purpose of testing the physical and chemical properties of the consignment to meet specified requirements.

  Shipper means any person by whom or in whose name, or on whose behalf, a contract of carriage of goods by sea has been concluded with a carrier, or any person by whom or in whose name, or on whose behalf, the goods are actually delivered to the carrier in relation to the contract of carriage by sea.

  Solid bulk cargo means any cargo, other than a liquid or a gas, consisting of a combination of particles, granules or any larger pieces of material generally uniform in composition which is loaded directly into the cargo spaces of a ship without any intermediate form of containment.

  Sources of heat means heated ship structures, where the surface temperature is liable to exceed 55ºC. Examples of such heated structures are steam pipes, heating coils, top or side walls of heated fuel and cargo tanks, and bulkheads of machinery spaces.

  Stowage factor means the figure which expresses the number of cubic metres which one tonne of cargo will occupy.

  Transportable moisture limit (TML) of a cargo which may liquefy means the maximum moisture content of the cargo which is considered safe for carriage in ships not complying with the special provisions of 7.3.2. It is determined by the test procedures, approved by a competent authority, such as those specified in paragraph 1 of appendix 2.

  Trimming means any levelling of a cargo within a cargo space, either partial or total.

  Ventilation means exchange of air from outside to inside a cargo space.

  • .1 Continuous ventilation means ventilation that is operating at all times.

  • .2 Mechanical ventilation means power-generated ventilation.

  • .3 Natural ventilation means ventilation that is not power-generated.

  • .4 Surface ventilation means ventilation of the space above the cargo.
