NF EN ISO 7536

August 1996
Standard Current mandatory application standard
Petroleum products. Determination of oxidation stability of gasoline. Induction period method.

The principle of the method specified is oxidizing the sample in a pressure bomb initially filled at 15 °C to 25 °C with oxygen at 690 kPa, heating at a temperature between 98 °C and 102 °C, reading the pressure at stated intervals or recorded continuously until the breakpoint is reached. The time required for the sample to reach this point is the observed induction period at the temperature of test, from which the induction period at 100 °C may be calculated. The method is applicable for aviation and motor gasolines in their finished form only.

Shell boilers - Part 11 : acceptance tests

Le présent document décrit une procédure d'évaluation des performances thermiques des chaudières utilisant de la vapeur ou de l'eau surchauffée. Cette procédure indirecte (déperditions) fournit un moyen approprié d'évaluation des chaudières thermodynamiquement simples, c'est-à-dire ayant une seule source principale d'apport calorifique et un circuit simple pour l'eau, la vapeur ou le fluide caloporteur à température élevée.
