This European Standard specifies a method for the determination of the softening point of bitumen and bituminous binders in the range of 28°C to 150°C. Technical warning - The change from mercury thermometers to electronic temperature devices has revealed that the temperature definition in the mercury thermometer has not been precise enough to make a correct, unbiased transfer to electronic devices. Care should be taken for softening points ring and ball above 100°C as the condition may have changed from previous practise to present days testing equipment. Below approx. 100°C the difference in temperature readings between electronic and mercury stem thermometer is acceptable compared to the repeatability of this test methods. [Reference: ASTM E20 Group] NOTE The method described is also applicable to bituminous binders that have been recovered from bituminous mixes, e.g. by extraction. WARNING— Use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
