    11、deltamethrin in a hydrocarbon solvent that, when further diluted with an organic solvent, is intended for use as an interior insecticidal timber preservative. NOTE Deltamethrin does not afford any fungicidal timber protection. The possibility does, however, exist of obtaining broad-spectrum activity

    12、, when deltamethrin is combined with a recognized and compatible fungicide. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this standard. All standards are subject to revision and, since any reference to a standard is

    41、me at least 1 L: Take samples of approximately equal volume from the containers and immediately pour the samples into a clean, dry, airtight glass or plastics bottle clearly marked with the manufacturers name or trade mark, the batch identification and the date of sampling. Before drawing a sample,

    42、thoroughly mix the contents of the relevant container. B.2.4 Compliance with the standard The lot shall be deemed to comply with the requirements of this standard if, after inspection of the containers and testing of the sample taken in accordance with B.2.3, no defective is found.
