MANUAL OF TESTS AND CRITERIA. The fifth revised to edition of the United Nations publication entitled Rec-
M
ommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria and Amendment 1 (ST/SG/AC.10/11/Rev.5 and Amend.1).
MASS. —see WEIGHT.
MASS EXPLOSION. An explosion that affects almost the entire load virtually instantaneously.
MATCHES, SAFETY (BOOK, CARD, OR STRIKE-ON-BOX). Are matches intended to be struck on a prepared surface.
MATCHES, STRIKE-ANYWHERE OR FUSEE. Usually contain phosphorus sesquisulphide, potassium chlorate and other ingredients. The strike-anywhere matches are readily ignited by friction on almost any dry surface. When a closed package of strike-anywhere matches is ignited by impact or friction the head composition burns off the matches and the fire then usually goes out unless the package is broken. If the package is broken, allowing access of air, the fire will continue. Packages of these matches that have been wetted for any reason and subsequently dried should be handled with extreme caution.
MAXIMUM CAPACITY. As used in Section 6 is the maximum inner volume of receptacles or packagings expressed in litres.
MAXIMUM NET MASS. As used in Section 6 is the maximum net mass of contents in a single packaging or maximum combined mass of inner packagings and the contents thereof expressed in kilograms.
MAXIMUM NORMAL OPERATING PRESSURE. (Radioactive Material Only). The maximum pressure above atmospheric pressure at mean sea-level that would develop in the containment system in a period of one year under the conditions of temperature and solar radiation corresponding to environmental conditions of transport in the absence of venting, external cooling by an ancillary system or operational controls during transport.
MAXIMUM TRANSPORT TEMPERATURE. The maximum temperature likely to be encountered by a substance in transport.
METAL CATALYST, FINELY DIVIDED, ACTIVATED, OR SPENT. Is metal in an extremely finely divided form. It must be shipped wet in moisture-tight and airproof pack-agings. If exposed to air, the metal may become hot and may even ignite.
METAL HYDRIDE STORAGE SYSTEM. A single complete hydrogen storage system, including a receptacle, metal hydride, pressure relief device, shut-off valve, service equipment and internal components used for the transport of hydrogen only.
METHYLACETYLENE AND PROPADIENE MIXTURE, STABILIZED. A flammable gas mixture that is reasonably stable at ordinary temperatures. While this is an acetylene
derivative, the gas is not shipped dissolved in liquid and the cylinders do not require an absorbent filler.
MINES. Articles normally consisting of metal or compo-
M  sition receptacles and a bursting charge. They are de-
to  signed to be operated by the passage of ships, vehicles or personnel. The term includes “Bangalore torpedoes”.
O MISCIBLE. The ability of a liquid (or gas) to dissolve uniformly in another liquid (or gas). Miscibility depends on the chemical nature of the substances involved and in some cases, liquids may only be partially miscible. Liquids that do not mix at all are said to be immiscible.
MIXTURE. Mixture means a material composed of more than one chemical compound or element.
MOTOR FUEL ANTI-KNOCK MIXTURE. A mixture of one or more organic lead compounds such as tetraethyl lead, triethylmethyl lead, diethyldimethyl lead, ethyltrimethyl lead, and tetramethyl lead, with one or more halogen compounds such as ethylene dibromide and ethylene dichloride.
MULTILATERAL APPROVAL. (Radioactive Material Only). The approval of a design by the competent authorities of the State of origin and of each State through or into which (see Note) the consignment is to be transported.
Note:
The term “through or into” specifically excludes “over”, i.e. the approval and notification requirements would not apply to a State over which radioactive material is carried in an aircraft, provided that there is no scheduled stop in that State.
MULTIPLE-ELEMENT GAS CONTAINERS (MEGCs). Are multi modal assemblies of cylinders, tubes and bundles of cylinders which are interconnected by a manifold and which are assembled within a framework. The MEGC includes service equipment and structural equipment necessary for the transport of gases. Not permitted for air transport.
NET EXPLOSIVE MASS (NEM). The total mass of the explosive substances, without the packagings, casings, etc. (net explosive quantity (NEQ), net explosive contents (NEC), or net explosive weight (NEW) are often used to convey the same meaning).
NET QUANTITY. The weight or volume of the dangerous goods contained in a package excluding the weight or volume of any packaging material. For the purposes of this definition “dangerous goods” means the substance or article as described by the proper shipping name shown in Table 4.2, e.g. for “Fire extinguishers” the net quantity is the weight of the fire extinguisher. For articles packed with equipment or contained in equipment, the net quan-tity is the net weight of the article, e.g. for lithium ion batteries contained in equipment, the net quantity is the net weight of the lithium ion batteries in the package.
NITRATING ACID MIXTURE. A mixture of nitric and sulphuric acids used for the nitration of glycerine, cellu-lose or other organic substances. This acid mixture coming in contact with organic matter commonly causes fire, unless the mixture contains much water.
766
NOT RESTRICTED. Means not subject to or restricted by these Regulations, except as otherwise stated.
OIL GAS COMPRESSED. A gas made by the reaction of steam at high temperatures on gas oil or similar fractions of petroleum, or by high temperature cracking of gas oil. The gas is flammable but is classified as a toxic gas because it contains a high proportion of Carbon Monoxide.
OPEN CRYOGENIC RECEPTACLE. A transportable ther-mally insulated receptacle for refrigerated liquefied gases maintained at atmospheric pressure by continuous vent-ing of the refrigerated liquefied gas.
