1、INTERNATIONAL STANDARD IS0 561 Second edition 1989-12-01 Corrected and reprinted 1992-05-15 Coal preparation plant - Graphical symbols Appareils utilis b) the symbols should be easy to draw and readily distinguishable from one another; c) the symbols should preferably give some indication of the pri

2、nciple of the operation involved, but should not represent the appearance of any particular type of machine; d) where a single symbol represents a group of items for which separate symbols are standardized nationally, it is preferable that the IS0 symbols are readily distinguishable from any one of

3、the national symbols. It is expected that the general adoption of the basic symbols in this standard will simplify the exchange of information between those concerned with the design, con- struction and operation of coal preparation plant. iii INTERNATIONAL STANDARD IS0 561 : 1989 (El Coal preparati
