NDT info literature search vol 14 no 6

literature search vo114 NDTInfo is a current service covering all aspects of non-destructive te4ting and is compiled by the Nondestructive Testing Centre. AERE. Harwell, Didcot. Oxen, UK The entries for NDT Info are drawn from over 2.000 British and international publications. Sections correspond to methods of testing (see list), and each entry within a section consists of the serial number in the Harwell NDT Centre Information Store for identification purposes; the title of the paper, book or report: the name of the author; and the name of the source journal or document. Where necessary, author's names and the title of foreign journals have been transliterated into the Latin alphabet according to British Standard BS 2979:1958
