690-2018-4 Rheological Properties of Unvulcanized Rubber Using Alpha Technologies RPA

Rheological properties of two compounds are determined using an Alpha Tehnologies Rubber Process Analyzer (RPA). Parts A and B of ASTM Test Method D6204 are referenced.

Laboratories may report a number of properties including: Storage shear modulus at 20 Hz (Part A, low strain), loss shear modulus at 20 Hz (Part A, low strain), storage shear modulus at 1.0 Hz (Part B, moderate strain) and loss shear modulus at 1.0 Hz (Part B, moderate strain).

Samples are tested at a low strain of 7% for Part A and a moderate strain of 100% (or higher) for Part B.

Total Number of Shipments = 4

Samples ship in January, April, July and October of 2018.

IMPORTANT: Please note that this test takes place during 2018. You must enroll no later than December 10, 2017. Test materials will ship at the end of January 2018, as indicated above.
