ISO 1125 Standard Test Method for Determination of Rubber Compound Components, Carbon Black, Ash

EUROLAB laboratory provides testing and compliance services within the scope of ISO 1125 standard. ISO 1125 specifies a method for determining the ash of any type of carbon black for use in the rubber industry.

An accurately weighed portion of the dried sample is ignited in a crucible until all the carbonaceous material is oxidized. The crucible is cooled in a desiccator, weighed and the ash percentage calculated.

The reproducibility of the result was determined as r 0,06% ash. Two separate test results (or determinations) with an ash difference of more than 0,06% will be considered suspicious and will require some appropriate investigative measures to be taken.

The reproducibility of the result was determined as R 0,09% ash. Two separate test results (or determinations) produced in separate laboratories with an ash difference of more than 0,09% will be considered suspicious and will require some appropriate investigative measures to be taken.

In test method terminology, bias is the difference between an average test value and a reference (correct) test feature value. Since the value of the test property is defined only by the test method, reference values ​​are not available for this test method. Therefore, bias cannot be determined.
