Standard history
This document specifies the reference method used for type testing and in cases of dispute for the determination of the particle density of filler by means of a pyknometer. For other purposes, in particular factory production control, other methods can be used provided that an appropriate working relationship with the reference method has been established. NOTE Methods for determination of particle density of aggregates are specified in EN 1097 6. Annexes are included that specify the procedures for calibration of the pyknometer (Annex A) and determination of the density of the liquid used to determine the particle density of the filler (Annex B). Annex C (informative) contains precision data. WARNING - The use of this part of EN 1097 can involve hazardous materials, operations and equipment (such as liquids, dust, noise and heavy lifts). It does not purport to address all of the safety or environmental problems associated with its use. It is the responsibility of users of this document to take appropriate measures to ensure the safety and health of personnel and the environment prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.
