UNITS OF MEASURE
Units of measure used in this manual are those
adopted by the International System which replace the
units previously used by the M.K.S. system.
Force:
decanewton (daN) replaces kilogram
(kg)
Pressure: bar, replaces kg/cm
2
Torque:
decanewton x meter (daNm) replaces
kgm
The following tables is to be used to convert units of
measure:

Note - For current service use, the following
equivalences can be considered to be valid:
kg = daN; kg/cm2 = bar; kgm = daNm.

CLASSIFICATION
OF STANDARD COMPO-
NENTS TO DETERMINE THE TIGHTENING TOR-
QUES
Note - In case, in the different sections, the tighten-
ing torque is not listed, refer to the table 'TIGHTEN-
ING TORQUES", only after identifying exactly the
component.
The latter is identified by a coded eight digit number,
allowing a complete description of the item.
Example.
I - Standard index digit
It is always represented by the digit 1. This number
indicates that the item can be fabricated in a number
of versions differing for material and coating.
a - b - c - d - e - Standard base digits
It is a number always composed of five digits identi-
fying dimensional specifications of the item.
f - Material index digit
This digit indicates the material used for a defined
item. Its meaning is indicated in the table thatfollows.
g - Coating index digit
It indicates the coating applied to a defined item.
