Animal and vegetable fats and oils - Determination of the composition of fatty acids in the 2-position of the triglycerides molecules (ISO 6800:1997)

Specifies the method for tensile testing of thin film materials with length and width under 1 mm and thickness under 10  m, which are main structural materials for micro-electromechanical systems (MEMS), micromachines and similar devices.
The main structural materials for MEMS, micromachines and similar devices have special features such as typical dimensions in the order of a few microns, a material fabrication by deposition, and a test piece fabrication by non-mechanical machining using etching and photolithography. This International Standard specifies the testing method, which enables a guarantee of accuracy corresponding to the special features.

Tierische und pflanzliche Fette und Öle - Bestimmung der Zusammensetzung von Fettsäuren in der 2-Stellung von Triglyceridmolekülen (ISO 6800:1997)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Zusammensetzung von Fettsäuren fest, die in 2-Stellung (beta-oder Innenstellung) der Triglyceridmoleküle in tierischen und pflanzlichen Fetten und Ölen verestert sind. Wegen der Wirkung der Pankreaslipase ist das Verfahren nur auf Fette und Öle mit einem Schmelzpunkt unter 45°C anwendbar.

Corps gras d'origines animale et végétale - Détermination de la composition des acides gras en position 2 dans les triglycérides (ISO 6800:1997)

La présente Norme internationale spécifie une méthode de détermination dans les corps gras d'origines animale et végétale de la composition de la fraction des acides gras estérifiés en position 2 (position β ou position interne) dans les triglycérides. En raison des particularités d'action de la lipase pancréatique, la méthode s'applique seulement aux corps gras ayant un point de fusion inférieur à 45 °C. Elle n'est pas applicable sans restrictions à tous les corps gras, en particulier à ceux renfermant des quantités importantes -- soit d'acides gras ayant 12 atomes de carbone ou moins (par exemple huiles de coprah et de palmiste, matières grasses butyriques du beurre); -- soit d'acides gras ayant 20 atomes de carbone et plus et d'insaturation élevée (plus de quatre doubles liaisons) (par exemple huiles de poissons et d'animaux marins); -- soit d'acides gras possédant des fonctions oxygénées secondaires.  
NOTE -- Les acides gras avec doubles liens en position (n-16) à (n-11) (par exemple acide pétrosélinique) ne sont convertis que très lentement par lipase pancréatique, ce qui pourrait donner des résultats erronés.

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.
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.
International Standard ISO 6800 was prepared by Technical Committee
ISO/TC 34, Agricultural food products, Subcommittee SC 11, Animal and
vegetable fats and oils.
This second edition cancels and replaces the first edition (ISO 6800:1985),
which has been technically revised.
Annexes A to C of this International Standard are for information only.

INTERNATIONAL STANDARD  ISO ISO 6800:1997(E)
Animal and vegetable fats and oils — Determination of the
composition of fatty acids in the 2-position of the triglyceride
molecules
1 Scope
This International Standard specifies a method for the determination of the composition of fatty acids
which are esterified in the 2-position (ß or internal position) of the triglyceride molecules in animal and
vegetable fats and oils.
Because of the nature of pancreatic lipase action, the method is applicable only to fats and oils with a
melting point below 45 °C.
The method is not unreservedly applicable to all fats and oils, particularly those containing substantial
amounts of
- fatty acids with 12 or fewer carbon atoms (e.g. copra oil, palm kernel oil, butyric butter fats);
- fatty acids with 20 and more carbon atoms and of a high degree of unsaturation (more than four
double bonds) (e.g. fish oil and marine animal oil);
- fatty acids which have secondary groups containing oxygen.
NOTE — Fatty acids with double bonds in the (n-16) to (n-11) position (e.g. petroselinic acid) are converted only
very slowly by pancreatic lipase. This may lead to wrong results.
