8、 Introduction This Japanese Industrial Standard has been made based on IS0 3753 Vacuum technology-Graphical symbols published in 1977 as the first edition, without changing the technical contents of the corresponding parts (classification and graphical symbols). However, the graphical symbols of som
9、e classes which are not specified in the corresponding International Standard are added as a part of Japa- nese Industrial Standard. The graphical symbols given in the body of this Standard (3.1) to (3.7) which are underlined with dots are those for the classes not specified in the corresponding In-
10、 ternational Standard. 1 Scope This Standard specifies the graphical symbols used in the vacuum tech- nology. Remarks : The following standard is the corresponding International Standard to this Standard: IS0 3753 Vacuum technology-Graphical symbols 2 General For convenience on drawings, it is permi
11、tted-with the exception of valves-to change the recommended positioning of inlets and outlets to devices, pro- vided that this does not create confusion among the basic symbols. The relative sizes of two or more symbols in combination shall correspond ap- proximately to those shown in Annex (informa
12、tive). 3 Graphical symbols 3 . 1 Vacuum pumps No. 3.1 3 . 1 . 1 Remarks : The arrows are optional and will be omitted when no confusion is possible with another sym- bol.
