Revision of D3265-23 Standard Test Method for Carbon Black—Tint Strength

Rationale

This ballot removes references to the need of a tint calculation correction factor. The requirement of a tint correction goes back to raw materials produced before 2012 in combination with ITRB2 and ZnO#8. ZnO#8 is depleted, no more commercially available and most probably used up in the labs. A reference to raw materials older than 10 years shall be avoided as aging of the raw materials over such a long time may also have an impact (unknown) on the result.
