LABORATORY EQUIPMENT

The producers guarantee the quality of carbon blacks from the factories to the customers. 
 
In our laboratory we check all features of the incoming goods that can change during the transport like:
 
• fine content
• heating loss
• sieve residue
• pellet hardness
 
We qualify the carbon black according to the ASTM standard.
 
Should our customers require more quality checks, we are able to carry out further tests on the products in an independent laboratory.
 

We are measuring by the ASTM standards in our laboratory the properties what can change during the transportation:

ASTM D 1508 standard,

equipment: RO-TAP

Sieve residue No  325:

ASTM D 1514 standard,

equipment: according to standard, individual prepared equipment

Heating loss:

ASTM D 1509 standard,

equipment:
