Arti dan kegunaannya

4.1 Dalam kondisi tertentu, pertumbuhan alga kontaminasi cat dan film adalah fenomena umum. It is well known that differences in environment, lampu, suhu, substrat, and other factors in addition to paint compositions can affect the susceptibility of a given painted surface. This test method attempts to provide a way to compare and evaluate the relative properties of different coating formulations under given conditions. This does not mean that a coating that resists growth under these conditions will necessarily resist growth in real-world applications (Lihat Catatan 1).

4.2 Familiarity with microbial technology is required. People without at least basic microbiological training should not use this test method.

Melangkah 1: Cakupan

1.1 The test method includes an accelerated method for determining the relative resistance of paint or coating to algal growth.

Catatan 1 – The rankings for relative performance of hope are similar to those for outdoor exposure. Namun, this test method should not be used as a substitute for external exposure because many other factors, only some of which are listed, can affect these results.
