Solid biofuels - Determination of particle density of pellets and briquettes (ISO 18847:2024)
EN ISO 18847:2024

ISO 18847:2016 specifies the method for determining the particle density of compressed fuels such as pellets or briquettes. Particle density is not an absolute value and conditions for its determination have to be standardized to enable comparative determinations to be made.

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.

Laboratory glass and plastic ware - Volumetric instruments - Methods for testing of capacity and for use (ISO 4787:2021)
EN ISO 4787:2021

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.

Fibre-reinforced plastics - Moulding compounds and prepregs - Determination of mass per unit area and fibre mass per unit area (ISO 10352:2020)
EN ISO 10352:2020

This document specifies a method for the determination of the mass per unit area. It also specifies five
methods (Method A to Method E) for the determination of the fibre mass per unit area of moulding
compounds and prepregs. The five methods are as follows:
— Method A: Extraction by Soxhlet;
— Method B: Extraction by immersion in solvent in a beaker;
— Method C: Decomposition by loss ignition;
— Method D: Extraction by wet combustion;
— Method E: Method by calculation.
This document is applicable to the following types of materials:
— moulding compound and preimpregnated unidirectional sheet, tape, fabric and mats;
— prepregs in which any type of reinforcement (aramid, carbon, glass, etc.) and any type of matrix
(thermosetting or thermoplastic) has been used.
Typically, reinforcement fibres are coated with sizing or finishes. These normally dissolve with the
resin and are, therefore, included in the resin content.
This document is not applicable to the following types of prepregs:
— those containing reinforcements which are soluble (or partly soluble) in the solvents used to dissolve
the resin.

Metallic and other inorganic coatings - Measurement of mass per unit area - Review of gravimetric and chemical analysis methods (ISO 10111:2019)
EN ISO 10111:2019

This document gives guidelines for determining the average surface density over a measured area
of anodic oxide or of a coating deposited autocatalytically, mechanically, by chemical conversion,
by electrodeposition, by hot dip galvanizing and by chemical or physical vapour deposition using
gravimetric and other chemical analysis procedures that have attained some degree of national or
international standardization.
A variety of procedures are described and include:
— gravimetric procedures for chemical or electrochemical dissolution of the coating or the substrate
to determine the coating surface density;
— gravimetric procedures for weighing the uncoated substrate and the coated (finished) specimen to
determine the coating surface density;
— analytical procedures that utilize dissolution of the coating for determination of the coating surface
density by instrumental chemical analysis methods.
With the exception of the gravimetric method as described in ISO 3892, this document does not give the
measurement uncertainties of the methods cited.
