METHOD FOR THE QUANTITATIVE ANALYSIS OF BIS(TRI-N-BUTYLTIN) OXIDE PRESERVATIVE FORMULATIONS AND TREATED TIMBER : DETERMINATION OF TOTAL TIN

It is assumed that all the tin determined by these methods has been derived from bis(tri-n-butyltin)oxide and hence the tin content is expressed in terms of bis(tri-n-butyltin)oxide.
With aged samples of treated wood, it is occasionally difficult to acid extract all the tin, particularly if iron or some other Cations are present. The method described in 2.4.4 has been shown to ensure that, in all cases, the proportion of tin not extracted is unlikely to affect the validity of the dete Close

The complex nature of the tar oil type preservatives precludes the use of a specific qualitative test for this group, although some indication of theIr presence may be provided by odour and appearance characteristics.

The procedures described in this standard will frequently be applied before carrying out quantitative analyses using methods described in other standards. Two types of qualitative test are described, those carried out directly on timber sections and those requiring prior preparation of an extract from the timber sample. Some preservative materials can be detected by either type of method, others by only one of them. In addition to the detection of preservative materials, the spray tests described may be used to estimate the penetration of the preservatives. Close
