NB Not all sizes are DIN standardized.
In connection with environmental requirements the
asbestos in this sealing has been replaced by mineral fibers with the trade name of ISO PLAN 750.
This material increases the insulation value by approximately 30% and the temperature durability
to 850 șC.
Tolerance field of d1 up to 23 is +0.5 +0.2,
from 23 this is +0.6 +0.3
Tolerance field of d2 is -0.1 -0.3
Tolerance field of s1 (type A) is -0.2 +0.2
Tolerance field of s2 (type C) is for 1.5: ±0.2 for 2: ±0.3 and for 3: ±0.4
