Animal and vegetable fats and oils - Determination of conventional mass per volume (litre weight in air) (ISO 6883:2017)

This document 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 to fats only when they are in a liquid state. Milk and milk products (or fat
coming from milk and milk products) are excluded from the scope of this document.
NOTE The determination of conventional mass per volume (litre weight in air) using the oscillating U-tube
method can be found in ISO 18301.

Corps gras d'origines animale et végétale - Détermination de la masse volumique conventionnelle (poids du litre dans l'air) (ISO 6883:2017)

ISO 6883:2017 spécifie une méthode de détermination de la masse volumique conventionnelle («poids du litre dans l'air») des corps gras d'origines animale et végétale (appelés corps gras dans la suite du texte) afin de convertir le volume en masse et inversement.
Le mode opératoire s'applique aux corps gras uniquement lorsqu'ils sont à l'état liquide. Le lait et les produits laitiers (ou les corps gras issus du lait et des produits laitiers) sont exclus du domaine d'application du présent document.
NOTE          La détermination de la masse volumique conventionnelle (poids du litre dans l'air) à l'aide de la méthode du tube en U oscillant peut être trouvée dans l'ISO 18301.

Živalske in rastlinske maščobe in olja - Določanje dogovorjene mase na enoto prostornine (masa litra v zraku) (ISO 6883:2017)

Ta dokument določa metodo za določevanje dogovorjene mase na enoto prostornine (»masa litra v zraku«) v živalskih in rastlinskih maščobah in oljih (v nadaljnjem besedilu: maščobe), da se omogoči pretvorbo prostornine v maso ali mase v prostornino.
Postopek se uporablja samo za maščobe v tekočem stanju. Mleko in mlečni izdelki (ali maščoba iz mleka in mlečnih izdelkov) niso zajeti v tem dokumentu.
OPOMBA: Postopek določevanja dogovorjene mase na enoto prostornine (»masa litra v zraku«) z metodo z oscilirajočo U-cevjo je naveden v standardu ISO 18301.

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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www. iso. org/d irectives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www. iso. org/p atents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment,

as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the

Technical Barriers to Trade (TBT) see the following URL: ww w .iso. org/iso / foreword. html.

This document was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 11,

Animal and vegetable fats and oils.

This fifth edition cancels and replaces the fourth edition (ISO 6883:2007), of which it constitutes a

minor revision to exclude its applicability for fat coming from milk and milk products and to include

further precision data.

Animal and vegetable fats and oils — Determination of
conventional mass per volume (litre weight in air)
1 Scope

This document 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 to fats only when they are in a liquid state. Milk and milk products (or fat

coming from milk and milk products) are excluded from the scope of this document.

NOTE The determination of conventional mass per volume (litre weight in air) using the oscillating U-tube

method can be found in ISO 18301.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements 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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— IEC Electropedia: available at http:// www .electropedia .org/
— ISO Online browsing platform: available at https:// www .iso .org/ obp/
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 1 to entry: 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.

It should be fitted with a calibrated thermometer, graduated in divisions of 0,1 °C covering the relevant

temperature range.

ISO 6883:2017(E)
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.
