Liquefied petroleum gas and light hydrocarbons - Determination of density or relative density - Pressure hydrometer method (ISO 3993:1984)

The prescribed apparatus shall not be used for materials having gauge vapour pressures higher than 1,4 MPa (absolute vapour pressure 1,5 MPa) at the test temperature. Alternative calibration procedures are described, but only the one using a certified hydrometer is suitable for the determination of density to be used in calculations of qualities for custody transfer or fiscal purposes.

Gaz de pétrole liquéfiés et hydrocarbures légers - Détermination de la masse volumique ou de la densité relative - Méthode de l'aréomètre sous pression (ISO 3993:1984)

1.1 La présente Norme internationale spécifie une méthode pour la détermination de la masse volumique ou de la densité relative des gaz de pétrole liquéfiés et des hydrocarbures légers. L'appareillage prescrit ne doit pas être utilisé pour des produits dont les pressions de vapeur sont supérieures à 1,4 MPa, soit 14 bar (pression de vapeur absolue 1,5 MPa) à la température de l'essai. ATTENTION -- L'attention est attirée sur les risques encourus en manipulant des gaz de pétrole liquéfiés ou des hydrocarbures légers. Les réglementations concernant les codes de sécurité nationaux, locaux ou domestiques doivent toujours être strictement observées. 1.2 Différentes procédures d'étalonnage sont décrites; cependant pour la détermination de la masse volumique retenue dans les calculs de transferts de propriété ou à des fins physiques, il convient d'utiliser un aréomètre certifié.  
NOTE -- Une autre méthode de calcul de la masse volumique des gaz de pétrole liquéfiés à partir de l'an

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of developing International
Standards is carried out through IS0 technical committees. Every member body
interested in a subject for which a technical committee has been authorized 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.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council.
International Standard IS0 3993 was developed by Technical Committee ISO/TC 28,
Petroleum products and lubricants, and was circulated to the member bodies in
March 1983.
It has been approved by the member bodies of the following countries :
Austria Iran Sri Lanka
Australia Iraq Sweden
Belgium Israel Switzerland
Brazil Italy Turkey
Canada Japan United Kingdom
China Netherlands USA
Egypt, Arab Rep. of Norway USSR
