[MT/T 748-2007, definition 3.2] 3.7 shatter strength A measure of resistance to crushing. It is expressed as the percentage of the mass of briquette pieces larger than 13 mm to the mass of the original test briquette after a certain amount of briquette sample is dropped freely from a certain height according to specified conditions and methods. 3.8 undersize fraction The mass fraction of the product above the sieve that is smaller than the specified lower limit of particle size. [GB/T 483-2007, definition 3.2.37]4 Raw material requirementsThe raw materials for civil briquettes are anthracite, bituminous coal, and other coal products, such as semi-coke. Low-quality and inferior coal, such as lignite, middling, and coal slime, is prohibited from being used as raw materials for civil coal.5 Product categoriesCivil briquette includes honeycomb briquette and other briquette. Honeycomb briquette is divided into two categories based on its quality indexes. honeycomb briquette No. 1 and honeycomb briquette No. 2; other briquette is divided into two categories based on their quality indexes. briquette No. 1 and briquette No. 2.6 Requirements and test methods6.1 Various auxiliary materials and additives used in the processing of honeycomb briquette and other briquettes shall be non-toxic, harmless and odorless, and shall not cause secondary pollution during the use of briquettes. 6.2 The technical requirements and test methods for honeycomb briquettes are shown in Table 1. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
