This document specifies a method for determining the bulk density of solid biofuels using a standardized measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 63 mm while the maximum particle length is 200 mm. For fuels with a nominal top size larger than 63 mm, a different method is described.
Bulk density is not an absolute value; therefore, conditions for its determination have to be standardized in order to gain comparative measuring results.
NOTE            Bulk density of solid biofuels is subject to variation due to several factors such as vibration, shock, pressure, biodegradation, drying, and wetting. Measured bulk density can therefore deviate from actual conditions during transportation, storage, or transhipment.

This document gives information on an interlaboratory comparison for the determination of the time-dependent structural change (thixotropy) using rheological test methods. Thixotropy is the reversible, time-dependent decrease of shear viscosity η at a constant shear rate  or shear stress τ.
This document provides examples of fields of application, in which important material properties can be characterized by the thixotropy. These fields of application include:
—     effectiveness of rheological additives and thixotropic agents, respectively;
—     stability of the structure at rest (e.g. behaviour when starting to pump);
—     wet film thickness after processing;
—     levelling and sagging behaviour (e.g. without brushmarks or sag formation);
—     orientation of effect pigments.

This document gives information on an interlaboratory comparison for the determination of the yield point, using rheological test methods. The yield point is the shear stress τ below which a material does not flow.
This document provides examples of fields of applications, in which important material properties are characterized with the aid of the yield point. These fields of application include:
—    effectiveness of rheological additives;
—    shelf life (e.g. with regard to sedimentation, separation and flocculation);
—    stability of the structure at rest;
—    behaviour when starting to pump;
—    use in scraper systems;
—    wet-film thickness;

This document provides methods for the testing, calibration and use of volumetric instruments made from glass and plastic in order to obtain the best accuracy in use.
NOTE      Testing is the process by which the conformity of the individual volumetric instrument with the appropriate standard is determined, resulting in the determination of its error of measurement at one or more points.
This document is applicable to volumetric instruments with nominal capacities in the range of 100 µl to 10 000 ml. These include single-volume pipettes (see ISO 648), graduated pipettes (see ISO 835), burettes (see ISO 385), volumetric flasks (see ISO 1042 and ISO 5215), and graduated measuring cylinders (see ISO 4788 and ISO 6706).
The methods are not intended for testing of volumetric instruments with capacities below 100 µl such as micro-glassware.
This document does not deal specifically with pycnometers as specified in ISO 3507. However, the procedures specified for the determination of volume of glassware can, for the most part, also be followed for the determination of a pycnometer volume. For some types of pycnometers, special handling can be necessary.
