Ships and marine technology — Bioassay methods for screening anti-fouling paints — Part 4: Algae
This document specifies the laboratory test method for screening anti-fouling paints in a flow-through system using algae as the test organism. It is intended to be used in conjunction with ISO 21716-1, which specifies the general requirements of the test methods described in the other parts of the ISO 21716 series. The purpose of the test specified in this document is to determine the difference…
Microbiology of the food chain — Determination and use of cardinal values
This document establishes basic principles and specifies requirements and methods to determine cardinal values of bacteria and yeast strains.
These methods are based on (1) the determination of maximum specific growth rates of the studied strain grown in a defined range of values of the intrinsic or extrinsic factor under study and (2) on the use of secondary models to obtain the cardinal values…
Détermination du point d'éclair — Méthode Pensky-Martens en vase clos
