The units and numerical values given in()in this E tands除搞，rd
are based on the traditional units and are appended for
informative reference．
The standards cited in this Standard are shown in／．ttached
Table 2，and corre8ponding International Standards are
shown in Attached Table 3．
For the main terms used in this Standard徽探，the defini治东；ions in
and the rest of the terms shall be as follows：
Informative reference：The definitions for terms are given in IS0 5 598．
(1) maximum permissible working pressure The maximum value pe】missible
for pressure generated inside the cylinder．
Remarks：This means such pressures as internal pressure，which．results
from the absorption of energy when inertial loads are．topped封豆，
and surge pressure．which is generated when the direc：ion of oil
flow is changed．
(2)—nominal—pressure The pressure assigned for the purpose of cony(nient
designation缔禾，and the maximum value of the set pressures for reliev ng valves
provided in an oil hydraulic circuit using cylinders．
minimum operating pressure．The minimum pressure capable of，,uaran-
teeing the opera,on of the cylinder．
(4)—head—end Closed end of the cylinder．
(5)—rod—end End of a cylinder through which the piston rod passes．
