20、uropean Directive 97/23/EC. 3.2 The choice of the appropriate multiple (decimal multiple or sub-multiple) of unit is governed by convenience, the multiple chosen for a particular application being one which would lead to numerical values within a practical range. Therefore when indicating quantities

21、 it is recommended to choose decimal multiple or sub multiple quantities such that the resulting values are easy to handle, e.g. between 0,1 and 1 000. 4 Quantities, symbols and units Symbols and units for the quantities used in pressure equipment shall be in accordance with Tables 1 and 2, otherwis
