Determine the Mooney viscosity in accordance with IS0 289-1, on a test portion prepared as indicated in 3.2 (without massing).
If massing is necessary, maintain the mill roll surface temperature at 50 °C±5 °C (for rubbers with a low Mooney viscosity, a temperature of 35 °C±5 °C can be used). Massing, if used, shall be mentioned in the test report.
Record the result as ML(1+4) at 125 °C unless another test temperature (100 °C or 150 °C) and/or test time (1+8) min has been agreed by the interested parties.
The standard test formulations are given in Table 1, in which:
a) formulation 1 is applicable to non-oil-extended EPDMs with a nominal ethylene content not higher than 67 % by mass;
b) formulation 2 is applicable to non-oil-extended EPDMs with a nominal ethylene content equal to or higher than 67 % by mass;
c) formulation 3 is applicable to non-oil-extended low Mooney viscosity EPDMs;
d) formulation 4 is applicable to oil-extended EPDMS containing 50 or less parts by mass of oil per 100 parts of rubber;
e) formulation 5 is applicable to oil-extended EPDMs containing more than 50 but less than 80 parts by mass of oil per 100 parts of rubber;
f) formulation 6 is applicable to oil-extended EPDMs containing 80 or more parts by mass of oil per 100 parts of rubber.ISO 4097 pdf download.
