of a plying one or mor e of the folowing pr es ures:

a) 2k a ±0,2 k a;

b) 5k a ±0,5 k a;

c) 1 k a ± 1,0 k a;

d) 24 k a ± 2,4 kPa

NOTE 1 In case of the pres ure fo t of 1 mm diamet er, the for e is calculat ed from the pres ure for e ch

a) 0,1 7 N± 0,0 6 N

b) 0,3 3 N± 0,0 9N

c) 0,78 N ±0,079 N

d) 1,8 N ± 0,1 N

NOTE 2 T e actual pres ure ex erted by the pres er fo t can b calculat ed in one of the fol owing ways:

a) by determining

1) the for e ex erted by the pres er fo t as embly, using a calibrated cou t erb lance, an

2) the surface are of the pres er fo t by direct me surement,

or

b) by using a tension dial g ug
