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 3.
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 part of ISO 7507 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 7507-5 was prepared by Technical Committee ISO/TC 28, Petroleum products and
lubricants, Subcommittee SC 3, Static petroleum measurement.
ISO 7507 consists of the following parts, under the general title Petroleum and liquid petroleum products —
Calibration of vertical cylindrical tanks:
— Part 1: Strapping method
— Part 2: Optical-reference-line method

4Principle
The tank and its surrounds are visually inspected and, having calculated the number of stations required, the siting
of the measurement stations is chosen.
Tripods, together with their respective measuring equipment, are placed at the initial stations. To establish the
position of the "at" station, angular and distance measurements are made from the initial "at" station to the initial
"back" and "forward" stations. Angular and distance measurements to the top and base of the tank are then taken
together with tangential angular measurements bisecting (3.3) the tank shell to the right and left of the station.
These measurements are made at the required positions on each course. The tripods at the initial "back" and "at"
stations are left in position to enable closure of the traverse on completion of the calibration.
From each of the subsequent, predetermined stations, angular and distance measurements to the top and base of
the tank are then taken, together with tangential angular measurements bisecting (3.3) the tank shell to the right
and left of the station.
In moving to each new station, the old "forward" station becomes the new "at" station and the old "at" station the
new "back" station. The final measurements are made from an "at" station which was the initial "back" station; the
final "forward" station is the initial "at" station.
These measurements, after any adjustments for misclosure, allow the calculation of three dimensional coordinates
which are fitted into a matrix describing the tank mathematically. The circumferences at the various vertical
positions on the tank shell are calculated from this information and the capacity table developed in accordance with
ISO 7507-1.

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 3.
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 part of ISO 7507 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 7507-5 was prepared by Technical Committee ISO/TC 28, Petroleum products and
lubricants, Subcommittee SC 3, Static petroleum measurement.
ISO 7507 consists of the following parts, under the general title Petroleum and liquid petroleum products —

misclosure
difference between the sum of the horizontal angles measured between the various stations of a complete traverse
of the tank and the sum of the theoretical angles for the same traverse
3.7
station
position from which measurements of angles and slope distance are made
3.8
tribrach
device, set on a tripod, which, by adjusting three or more foot screws, is set in a horizontal plane and upon which
surveying instruments are mounted
4Principle
The tank and its surrounds are visually inspected and, having calculated the number of stations required, the siting
of the measurement stations is chosen.
Tripods, together with their respective measuring equipment, are placed at the initial stations. To establish the
position of the "at" station, angular and distance measurements are made from the initial "at" station to the initial
"back" and "forward" stations. Angular and distance measurements to the top and base of the tank are then taken
together with tangential angular measurements bisecting (3.3) the tank shell to the right and left of the station.
These measurements are made at the required positions on each course. The tripods at the initial "back" and "at"
stations are left in position to enable closure of the traverse on completion of the calibration.
From each of the subsequent, predetermined stations, angular and distance measurements to the top and base of
the tank are then taken, together with tangential angular measurements bisecting (3.3) the tank shell to the right
and left of the station.
In moving to each new station, the old "forward" station becomes the new "at" station and the old "at" station the
new "back" station. The final measurements are made from an "at" station which was the initial "back" station; the
final "forward" station is the initial "at" station.
These measurements, after any adjustments for misclosure, allow the calculation of three dimensional coordinates
which are fitted into a matrix describing the tank mathematically. The circumferences at the various vertical
positions on the tank shell are calculated from this information and the capacity table developed in accordance with
ISO 7507-1.

4Principe
Le réservoir et ses alentours sont inspectés visuellement, et aprèsavoir établi le nombre de points de station
nécessaires, l’emplacement des points de station est sélectionné.
Les trépieds et leur équipement respectif de mesurage sont placés aux points de station origines. Les mesures
d’angles et de distance sont effectuées à partir du point de station «stationencours» jusqu’aux points de station
«station précédente» et «station suivante»,afin d’établir la position de la «station en cours». Les mesurages des
angles et de la distance à la partie supérieure et à la base du réservoir sont effectués en une fois, ainsi que les
mesurages tangentiels d’angle de visée (3.3) de la paroi du réservoir à droite et à gauche du point de station. Ces
mesurages sont effectués pour chaque virole aux emplacements adéquats. Les trépieds aux points de «station
précédente» et «station en cours» sont laissés en place pour s’assurer que le cheminement aura été complet à la
fin du jaugeage.
À partir de chaque point de station ainsi déterminéà l’avance, le mesurage des angles et des distances au bord
supérieur et à la baseduréservoir est effectué,enmême temps que les mesurages angulaires qui visent
tangentiellement la paroi du réservoir à droite et à gauche du point de station.
En se déplaçant sur chaque nouvelle station, l’ancien point de station «arrière» devient la «station en cours»,et
l’ancien emplacement «station en cours» devient le point de «station avant». Le dernier mesurage à partir de la
«station en cours» qui était auparavant le point de «station précédente» est effectué, la dernière «station suivante»
est maintenant la «station en cours» initiale.
