Tierische und pflanzliche Fette und Öle - Bestimmung der konventionellen volumenbezogenen Masse (Litergewicht in Luft) (ISO 6883:2007)
Diese Internationale Norm beschreibt ein Verfahren zur Bestimmung der konventionellen volumenbezogenen Masse („Litergewicht in Luft“) von tierischen und pflanzlichen Fetten und Ölen (im Folgenden Fette genannt), mit dem Ziel, Volumen in Masse bzw. Masse in Volumen umzurechnen.
Das Verfahren gilt nur für Fette im flüssigen Zustand.
Die Temperatur bei der Bestimmung des Fettes sollte so gewählt werden, dass sich bei dieser Temperatur keine Kristalle im Fett absetzen.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 6883 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 11, Animal
and vegetable fats and oils.
This fourth edition cancels and replaces the third edition (ISO 6883:2000), which has been been technically
revised.

INTERNATIONAL STANDARD ISO 6883:2007(E)
Animal and vegetable fats and oils — Determination of
conventional mass per volume (litre weight in air)
1 Scope
This International Standard specifies a method for the determination of the conventional mass per volume
(“litre weight in air”) of animal and vegetable fats and oils (hereinafter referred to as fats) in order to convert
volume to mass or mass to volume.
The procedure is applicable only to fats in a liquid state.
The temperature of determination applied for any fat should be such that the fat does not deposit crystals at
that temperature.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 661, Animal and vegetable fats and oils — Preparation of test sample
ISO 3507, Laboratory glassware — Pyknometers
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
conventional mass per volume
litre weight in air
quotient of the mass in air of fat to its volume at a given temperature
NOTE It is expressed in kilograms per litre (numerically equal to grams per millilitre).
4 Principle
The mass of a volume of liquid fat in a calibrated pyknometer is measured at a specified temperature.
5 Apparatus
Usual laboratory apparatus and, in particular, the following.
5.1 Water bath, capable of being maintained to within 0,1 °C of the temperatures chosen for the calibration
and determination.
ISO 6883:2007(E)
It should be fitted with a calibrated thermometer, graduated in divisions of 0,1 °C covering the relevant
temperature range.
5.2 Pyknometer (Jaulmes), of capacity 50 ml, with side-arm.
It should be fitted by means of conical joints with a calibrated thermometer graduated in divisions of 0,1 °C
and with a cap perforated at the top for the side-arm (see Figure 1).
The pyknometer should preferably be made of borosilicate glass, but if this is not available then one made of
soda glass may be used.
NOTE The cap is only essential if the determination is carried out at a temperature below ambient.
Alternatively, the Type 3 (Gay-Lussac) pyknometer (see Figure 2) specified in ISO 3507 may be used;
however, the use of a pyknometer with thermometer is preferred.

6 Sampling
A representative sample should have been sent to the laboratory. It should not have been damaged or
changed during transport or storage.
Sampling is not part of the metho
