Pri nekaterih mešanicah z visoko vsebnostjo klorovlaken se lahko preskusni vzorec med sušenjem močno skrči, zaradi česar se raztapljanje klorovlaken v topilu upočasni.
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.
V homogenih mešanicah vlaken znaša interval zaupanja ± 1 za dobljene rezultate pri 95-odstotnem statističnem zaupanju.
On a homogeneous mixture of textile materials, the confidence limits of the results obtained by this method are not greater than ± 1 for a confidence level of 95 %.

Po končani ekstrakciji se vzorec pusti na zraku, da topilo izhlapi; ostanki topila se dokončno odstranijo s sušenjem v sušilniku pri temperaturi 105 ± 3 ºC.
Allow the solvent to evaporate from the sample in air, and remove the last traces in an oven at 105 ± 3 ºC.
Vzorec se nato ekstrahira 30 minut z vodo (50 ml na gram vzorca) v bučki s povratnim hladilnikom pri temperaturi vrenja.
Then extract the sample in water (50 ml per g of sample) by boiling under reflux for 30 minutes.
Potem, ko se raztopina z vzorcem prefiltrira, se vzorec vrne v bučko, ekstrakcija pa ponovi z enako količino vode.
Filter, return the sample to the flask, and repeat the extraction with an identical volume of water.
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.
Filter, remove excess water from the sample by squeezing, suction, or centrifuging and then allow the sample to become air-dry.
Izvede se postopek izbire, sušenja in tehtanja primerka, kot je naveden v teh splošnih navodilih.
Follow the procedure described in the general instructions as regards the selection, drying and weighing of the specimen.
Preskusni primerek se vloži v Kjeldahlovo razklopno bučko.
Transfer the specimen to a Kjeldahl digestion flask.
Primerku mase najmanj 1 g se nato v bučki za razklop dodajo v naslednjem zaporedju: 2,5 g kalijevega sulfata, 0,1–0,2 g selenovega dioksida in 10 ml žveplove kisline (z relativno gostoto pri 20 ºC 1,84).
To the specimen weighing at least 1 g contained in the digestion flask, add, in the following order, 2,5 g potassium sulphate, 0,1 - 0,2 g selenium dioxide and 10 ml sulphuric acid (relative density at 20 ºC: 1,84).
Bučka se začne segrevati, sprva počasi, dokler se vlakna v celoti ne razgradijo, nato pa močneje, dokler se raztopina ne zbistri in postane skoraj brezbarvna.
Heat the flask, gently at first, until the whole of the fibre is destroyed, and then heat it more vigorously until the solution becomes clear and almost colourless.
Segrevanje se nadaljuje še nadaljnjih 15 minut, nakar se bučka z vsebino ohladi.
Heat it for a further 15 minutes.
Raztopina se pazljivo razredči z 10 do 20 ml vode, ponovno ohladi, kvantitativno prenese v merilno bučko prostornine 200 ml, dolije se ji voda do oznake, da nastane nasičena raztopina.
Allow the flask to cool, dilute the contents carefully with 10 -20 ml water, cool, transfer the contents quantitatively to a 200 ml graduated flask and make up to volume with water to form the digest solution.
V destilacijsko bučko se vlije natanko 10 ml nasičene raztopine, in v lij na aparatu se doda najmanj 5 ml raztopine natrijevega hidroksida, zamašek se rahlo privzdigne in pusti, da raztopina natrijevega hidroksida počasi steče v bučko.
Transfer exactly 10 ml of digest solution to the distillation flask, add not less than 5 ml of sodium hydroxide solution to the funnel, lift the stopper slightly and allow the sodium hydroxide solution to run slowly into the flask.
Če nasičena raztopina in raztopina natrijevega hidroksida ostaneta ločeni v dveh plasteh, ju je treba pomešati z rahlim stresanjem.
If the digest solution and sodium hydroxide solution remain as two separate layers, mix them by gentle agitation.
Sledi počasno segrevanje destilacijske bučke in dovajanje pare iz generatorja.
Heat the distillation flask gently and pass it into steam from the generator.
V erlenmajerici se zbere približno 20 ml destilata, nakar se jo spusti toliko, da je vrh dovodne cevi erlenmajerice približno 20 mm nad površino tekočine, nakar se destilacija nadaljuje še 1 minuto.
Collect about 20 ml of distillate, lower the conical flask so that the tip of the delivery tube of the condenser is about 20 mm above the surface of the liquid and distil for 1 minute more.
