This International Standard specifies, for narrow V-belts of cross-sections 9N/J (for pulley grooves of effective width 8,9mm), 15N/J (for pulley grooves of effective width 15,2mm) and 25N/J (for pulley grooves of effective width 25,4mm),
-
the standard effective lengths,
-
the tolerances on effective lengths,
-
the centre distance variations,
-
the conditions for measuring the effective length and the centre distance variation, and
-
the designation and marking.
NOTE1 The cross-section of a narrow V-belt is defined by a number (9, 15 or 25) followed by the letter N or J to denote single or joined belts.
NOTE2 To define belts of raw-edge cogged construction, the letter “X” is added, i.e. NX or JX.
