For other purposes, in particular factory productioncontrol, other methods may be used provided an appropriate working relationship with the reference method hasbeen established.The test method specified in this European Standard is applicable to particle size fractions di/Di where Di≤ 63 mm and di ≥ 4 mm.【中国标准分类号】: Q13【国际标准分类号】: 91_100_15【页数】: 14P.;A4【正文语种】: 英语
