(a) Not less than 90% ammonium nitrate with not more than 0.2% total

combustible/organic material calculated as carbon and with added matter, if

any, which is inorganic and inert towards ammonium nitrate; or

(b) Less than 90% but more than 70% ammonium nitrate with other inorganic

materials or more than 80% but less than 90% ammonium nitrate mixed with

calcium carbonate and/or dolomite and/or mineral calcium sulphate and not

more than 0.4% total combustible/organic material calculated as carbon; or

ammonium nitrate and ammonium sulphate with more than 45% but less

than 70% ammonium nitrate and not more than 0.4% total combustible/organic

material calculated as carbon such that the sum of the percentage compositions

of ammonium nitrate and ammonium sulphate exceeds 70%.

309 This entry applies to non sensitized emulsions, suspensions and gels consisting

primarily of a mixture of ammonium nitrate and fuel, intended to produce a Type E

blasting explosive only after further processing prior to use.

The mixture for emulsions typically has the following composition: 60-85%

ammonium nitrate, 5-30% water, 2-8% fuel, 0.5-4% emulsifier agent, 0-10% soluble

flame suppressants, and trace additives. Other inorganic nitrate salts may replace part

of the ammonium nitrate.

The mixture for suspensions and gels typically has the following composition: 60-85%

ammonium nitrate, 0-5% sodium or potassium perchlorate, 0-17% hexamine nitrate or

monomethylamine nitrate, 5-30% water, 2-15% fuel, 0.5-4% thickening agent, 0-10%

soluble flame suppressants, and trace additives. Other inorganic nitrate salts may

replace part of the ammonium nitrate.

Substances shall satisfactorily pass Test Series 8 of the Manual of Tests and Criteria,

Part I, Section 18 and be approved by the competent authority.

310 The testing requirements in sub-section 38.3 of the Manual of Tests and Criteria do

not apply to production runs consisting of not more than 100 cells and batteries, or to

pre-production prototypes of cells and batteries when these prototypes are carried for

testing, if:

(a) the cells and batteries are carried in an outer packaging that is a metal, plastics

or plywood drum or a metal, plastics or wooden box and that meets the criteria

for packing group I; and

(b) each cell and battery is individually packed in an inner packaging inside an

outer packaging and is surrounded by cushioning material that is non-

combustible, and non-conductive.

311 Substances shall not be carried under this entry unless approved by the competent

authority on the basis of the results of appropriate tests according to Part I of the

Manual of Tests and Criteria. Packaging shall ensure that the percentage of diluent

does not fall below that stated in the competent authority approval, at any time during

carriage.

312 (Reserved)

313 Substances and mixtures meeting the criteria for Class 8 shall bear a subsidiary risk

label conforming to model No. 8 (see 5.2.2.2.2).
