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.

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.

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.

This document specifies three methods for the determination of dry bulk density of soils calculated
from the mass and the volume of a soil sample. The methods involve drying and weighing a soil sample,
the volume of which is either known [core method (see 4.1)] or determined [excavation method (see 4.2)
and clod method (see 4.4)].

This part of IEC 61987 provides an
• operating list of properties (OLOP) for the description of the operating parameters and the
collection of requirements for a density measuring equipment, and
• device lists of properties (DLOP) for a range of density measuring equipment types
describing them.
The structures of the OLOP and the DLOP correspond with the general structures defined in
IEC 61987-11 and agree with the fundamentals for the construction of LOPs defined in
IEC 61987-10.
Aspects other than the OLOP, needed in different electronic data exchange processes
described in IEC 61987-10, will be published in IEC 61987-921.
Libraries of properties and of blocks used in the concerned LOPs are listed in Annex C and

This document describes a method of determining bulk density of solid biofuels by the use of a standard measuring container. This method is applicable to all solid biofuels with a nominal top size of maximum 100 mm.
Bulk density is not an absolute value, therefore conditions for its determination have to be standandised in order to gain comparative measuring results.
Note 1: The nominal top size is defined as the aperture size of the sieve where at least 95 % by mass of the material passes (ISO DIS 16559 (14588)).
Note 2: 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 and transhipment.

These non-gravimetric test methods can be applied: as aids to quality assurance by the supplier; as routine quality assurance and routine calibrations by the user; and as routine and post-repair testing. The methods described in ISO 8655-7:2005 are not applicable as alternatives to the gravimetric reference test methods specified in ISO 8655-6, which gives the only method suitable as a basis for supplier's declarations or independent certification of conformity.
