6. Where an explosive is authorized for manufacture and sale in Britain the definition of
   such explosive shall be that given in the current issue of the confidential list of authorized explosives
   published annually by the Home Office. The definition of an explosive not so authorized but
   approved by the Minister for importation into, and manufacture, storage, and sale in New
   Zealand shall be the description given by the manufacturer or his agent on application for authorization of such explosive, or such other description of the explosive as may from time to time be
   approved by the Minister.

7. For the purposes of the said Act explosives shall be divided into seven classes, as follows :—
   Class 1 .. .. Gunpowder. Class 5 .. .. Fulminate.
   Class 2 .. .. Nitrate-mixture. Class 6 .. .. Ammunition.
   Class 3 .. .. Nitro-compound. Class 7 .. .. Firework
   Class 4 .. .. Chlorate-mixture.
   And when an explosive falls within the description of more than one class it shall be deemed to
   belong exclusively to the latest of the classes within the description of which it falls.

8. The following explosives are at present authorized for importation into, and for manufacture, storage, and sale in, New Zealand :—

CLASS 1.—GUNPOWDER.
The term “gunpowder” means exclusively gunpowder ordinarily so called.
Gunpowder.

CLASS 2.—NITRATE-MIXTURE.
The term “nitrate-mixture” means any preparation, other than gunpowder ordinarily so called, formed by the mechanical mixture of a nitrate with any form of carbon or with any carbonaceous substance not possessed of explosive properties, whether sulphur is or is not added to such preparation, and whether such preparation is or is not mechanically mixed with any other non-explosive substance.
Every blasting-explosive in this class in which nitrate of ammonium is used as an ingredient shall be contained in cartridge wrappers or cases made thoroughly waterproof with melted paraffin or other suitable waterproofing material.
Ammonal B. Chilworth special powder.
Bobbinite. Ripping ammonal.

CLASS 3.—NITRO-COMPOUND.
The term “nitro-compound” means any chemical compound possessed of explosive properties, or capable of combining with metals to form an explosive compound, which is produced by the chemical action of nitric acid (whether mixed or not with sulphuric acid) or of a nitrate mixed with sulphuric acid upon any carbonaceous substance, whether such compound is mechanically mixed with other substances or not.
Every explosive in this class and every explosive ingredient thereof shall be so thoroughly purified and be otherwise of such character as to satisfy a test known as the “Abel heat test,” and specified in the reports of the Departmental Committee appointed by the British Home Office on the 21st April, 1909, to report on the standardization of this test.
Every blasting-explosive in this class in which nitrate of ammonium or nitrate of sodium are used as ingredients shall be contained in cartridge wrappers or cases made thoroughly waterproof with melted paraffin or other suitable waterproofing material.
