With certain mixtures having a high chlorofibre content there may be substantial shrinkage of the specimen during the drying procedure, as a result of which the dissolution of chlorofibre by the solvent is retarded.
Pri nekaterih mešanicah z visoko vsebnostjo klorovlaken se lahko preskusni vzorec med sušenjem močno skrči, zaradi česar se raztapljanje klorovlaken v topilu upočasni.

Allow the solvent to evaporate from the sample in air, and remove the last traces in an oven at 105 ± 3 °C.
Po končani ekstrakciji se vzorec pusti na zraku, da topilo izhlapi; ostanki topila se dokončno odstranijo s sušenjem v sušilniku pri temperaturi 105 ± 3 °C.
Then extract the sample in water (50 ml per g of sample) by boiling under reflux for 30 minutes.
Vzorec se nato ekstrahira 30 minut z vodo (50 ml na gram vzorca) v bučki s povratnim hladilnikom pri temperaturi vrenja.
Filter, return the sample to the flask, and repeat the extraction with an identical volume of water.
Potem, ko se raztopina z vzorcem prefiltrira, se vzorec vrne v bučko, ekstrakcija pa ponovi z enako količino vode.
Filter, remove excess water from the sample by squeezing, suction, or centrifuging and then allow the sample to become air-dry.
Po obdelavi se raztopina ponovno prefiltrira, iz vzorca se odvečna voda odstrani z ožemanjem, odsesevanjem ali centrifugiranjem, nato pa pusti, da se vzorec posuši na zraku.
The toxic effects of toluene and methanol shall be borne in mind and full precautions shall be taken in their use.
Pri delu je treba upoštevati varnostne ukrepe zaradi strupenosti toluena in metanola.
