通告描述：

This Draft East African Standard gives guidance on the general procedures to be followed in the sampling and preparation for analysis of preservatives and preservative-treated timber. No attempt has been made here to define rigidly any detailed methodology to be followed in operations in these areas because this can depend upon the nature of the preservative, the method of treatment, and the particular requirements of relevant approval authorities.

This Draft East African Standard is applicable to the provision of appropriate samples for analysis which may be used to check the content of active components in preservative formulations, and to determine the identity, location and concentration of preservatives in treated timber. The techniques described may be employed in a wide variety of applications ranging from laboratory research through to the checking of preservatives or preservative-treated timber for arbitration purposes. In most cases it is possible, by chemical analysis, to determine whether or not a sample of timber has received a preservative treatment and the results can often give an indication of the type of treatment the wood has received when due consideration is given to other relevant factors, such as timber species and heartwood/ sapwood ratio, in the samples under test.
