Le service d'analyse de la fibre noire propos\u00e9 par l'AWTA s'adresse aux producteurs de laine blanche qui tentent de g\u00e9rer la contamination par des races ovines exotiques ou qui souhaitent contr\u00f4ler la contamination de lots pr\u00e9sentant un risque \u00e9lev\u00e9 de contamination.<\/p>\n\n\n\n

Deux techniciens examinent visuellement quatre \u00e9chantillons, de 5 grammes chacun, d'une carotte lav\u00e9e et card\u00e9e en utilisant le d\u00e9tecteur de fibres sombres pour identifier les fibres sombres et m\u00e9dull\u00e9es pr\u00e9sentes. Ces \u00e9chantillons sont plac\u00e9s dans un sac en plastique scell\u00e9, dont l'air a \u00e9t\u00e9 exclu, o\u00f9 ils sont immerg\u00e9s dans un solvant ayant le m\u00eame indice de r\u00e9fraction que la laine. Les fibres de laine blanche deviennent transparentes, mais sous certaines conditions d'\u00e9clairage, les fibres sombres et m\u00e9dullaires deviennent visibles et peuvent \u00eatre compt\u00e9es. Ces r\u00e9sultats sont publi\u00e9s sous forme de rapports d'essai et pr\u00e9sent\u00e9s selon l'une des options suivantes :<\/p>\n<\/div>\n\n\n\n

Les producteurs qui souhaitent b\u00e9n\u00e9ficier de ce service doivent en faire la demande aupr\u00e8s de leur courtier ou agent de vente de laine avant que leurs lots ne soient \u00e9chantillonn\u00e9s en vue de la certification du rendement, de la base de mati\u00e8re v\u00e9g\u00e9tale et du diam\u00e8tre moyen de la fibre. <\/p>\n<\/div>\n<\/div>\n\n\n\n
