¡ These rubbers may be requested with additional characteristics (e.g. wear resistance, dielectric properties, etc.);
in this case the standard symbol on drawing shall be followed by the suffix corresponding to the required cha-
racteristcs, as per Std. Sh. 55031.
In particular, if higher resistance to low temperatures is prescribed, the required brittleness temperature value
shall be indicated on drawing.
© Permissible tolerances for part acceptance are as specified in Std. Sh. 50404/01.
¢ The IRHD (International Rubber Hardness Degrees) values correspond practically to the shore A hardness va-
lues (See Std. Sh. 50411).
£ Values obtained on linear specimens (lengthwise on tubular shapes).
¤ A minimum tearing of 30 N/mm (3 kg/cm) is allowed for extruded parts.
¥ In air at 120 ˚C for 70 h.
§ 100% in “Paraflù 11” fluid (Std. 55523/01).
¨ Used exceptionally .
