3.1 Mesh size regulations are divided into the first, second and third series, which are R10, R20 and R40 respectively. The first series (R10) is preferred. For mesh sizes less than 50μm, the size series are R10, R20 and R40.3.2 Mesh size series are shown in Table 1, Table 2 and Table 3.4 Dimension unit expression method
Mesh sizes greater than or equal to 1mm are expressed in mm (see Table 1); mesh sizes less than 1mm are expressed in μm (see Table 2 and Table 3).
