1. Diameters from 8 mm to 25 mm and gap settings from 0,5 mm to 2,0 mm have been found to be suitable for
bituminous binders. a. Plates of other diameters can also be used, providing compliance effects of the instrument do not affect the results (see 6.1, Note 1)
2. The fact that the temperature control range is 5 °C to 85 °C should not be taken to imply that accurate results
will necessarily be obtained for all binders over this range (see 5.1, Note 4 and 6.1, Note 1). Furthermore, temperatures
outside this range can also be used, provided the results are not affected by machine compliance.
3. The manufacturer may have determined the operational limits and this information may be available but, if not, it can be determined by running a test specimen over a range of test temperatures using all the test geometries likely to be used in practice, and plotting |G*| against either frequency or phase angle (δ). Where the divergence between the plots for each geometry exceeds 15 %, this is an indication that compliance effects are affecting one or more of the geometries.
