The RICE and AFRICA Schemes for asbestos fibre counting / N.P. Crawford, P. Brown and A.J. Cowie

Sumario: The Regular Interlaboratory Counting Exchanges (RICE) and the Asbestos Fibre Regular Informal Counting Arrangement (AFRICA) were initiated as U.K. and international schemes, respectvely, to improve standards of counting asbestos fibres using phase contrast optical microscopy. In both schemes, reference samples are evaluated by participating laboratories in rounds of sample exchanges, and counting performance is assessed by comparing laboratory counts with reference counts. This summary includes descriptions of the scope and scale of membership, the nature of refernece samples and reference counts, and their main operational features. Progress in developing both schemes further is described, particularly in relation to the nature of the reference samples and reference counts
