s of simulated service arc tests and field experience. Because this test method is usually conducted under clean and dry laboratory conditions rarely encountered in practice, the prediction of a material's relative performance in typical applications and in varying clean to dirty environments may be substantially altered (Note 0). Caution is urged against drawing strong conclusions without corroborating support of simulated service tests and field testing. Rather, this test method is useful for
