An appraisal of the Petrie Dish method of evaluating the susceptibility of tubular plastic insulations to the growth of fungi

摘要

During the course of the Southwest Pacific campaign it was found that many of the insulations in use at that time were particularily susceptible to attack by fungus growth. As a result of these findings specifications were written by the armed services relative to the fungus resistant properties of these materials. Procedures for testing these properties were devised and the one that is accepted at present for testing fungus resistance is the Petrie Dish Test.
