Izvede se postopek, opisan v splošnih navodilih, in nadaljuje, kot sledi:
Follow the procedure described in the general instructions and proceed as follows:
Preskusnemu primerku v erlenmajerici s prostornino najmanj 200 ml, se prilije 100 ml acetona na gram preskusnega primerka; elenmajerico se pretrese ter vsebino pusti stati 30 minut pri sobni temperaturi, pri čemer se jo od časa do časa pretrese; tekočino se nato odlije skozi predhodno stehtan filtrirni lonček.
To the test specimen contained in a glass-stoppered conical flask of at least 200 ml capacity, add 100 ml of acetone per gram of test specimen, shake the flask, stand it for 30 minutes at room temperature, stirring from time to time, and then decant the liquid through the weighed filter crucible.
Postopek se ponovi še dvakrat (skupaj se izvedejo tri ekstrakcije), vendar samo po 15 minut, tako da je skupni čas obdelave v acetonu ena ura.
Repeat the treatment twice more (making three extractions in all), but for periods of 15 minutes only, so that the total time of treatment in acetone is one hour.
Filtrirni lonček se znova napolni z acetonom in pusti, da tekočina odteče zaradi težnosti.
Refill the crucible with acetone and allow to drain under gravity.
Na koncu se tekočino odsesa iz filtrirnega lončka, filtrirni lonček pa z vsebino posuši, ohladi in stehta.
Finally, drain the crucible with suction, dry the crucible and residue, and cool and weigh them.
Rezultati se izračunajo, kot je opisano v splošnih navodilih.

METODA št. 2 DOLOČENA PROTEINSKA IN DRUGA VLAKNA (Metoda z uporabo hipoklorita)
METHOD No 2
Metoda je po odstranitvi nevlaknate snovi uporabna za naslednje dvokomponentne mešanice tekstilnih vlaken:
This method is applicable, after removal of non-fibrous matter, to binary fibre mixtures of:
bombažem (5), bakro vlakni (21), modalom (22), viskozo (25), akrilom (26), klorovlakni (27), poliamidom ali najlonom (30), poliestrom (35), polipropilenom (37), elastanom (43), steklenimi vlakni (44), elastomultiestrom (45), elastolefinom (46) in melaminom (47).

Proteinsko vlakno se iz mešanice znane suhe mase odtopi z raztopino hipoklorita.
The protein fibre is dissolved out from a known dry mass of the mixture, with a hypochlorite solution.
Odstotek suhih proteinskih vlaken se izračuna iz razlike.
The percentage of dry protein fibre is found by difference.
Za pripravo raztopine hipoklorita se lahko uporabi litijev hipoklorit ali natrijev hipoklorit.
Either lithium hypochlorite or sodium hypochlorite can be used for the preparation of the hypochlorite solution.
Litijev hipoklorit je priporočljiv v primerih, kjer gre za manjše število analiz ali za analize, ki se izvajajo v daljših presledkih.
Lithium hypochlorite is recommended in cases involving a small number of analyses or for analyses conducted at fairly lengthy intervals.
Razlog za to je, da je odstotek hipoklorita v trdnem litijevem hipokloritu – v nasprotju z natrijevim hipokloritom – skoraj konstanten.
This is because the percentage of hypochlorite in solid lithium hypochlorite ‐ unlike that in sodium hypochlorite ‐ is virtually constant.
OPREMA IN REAGENTI (poleg tistih, navedenih v splošnih navodilih)
APPARATUS AND REAGENTS (other than those specified in the general instructions)
erlenmajerica z brušenim steklenim zamaškom in prostornino 250 ml;
Erlenmeyer flask with ground-glass stopper, 250 ml;
termostat za vzdrževanje temperature erlenmajerice pri 20 (± 2) °C.
thermostat, adjustable to 20 (± 2) ºC.
Raztopina litijevega hipoklorita
Lithium hypochlorite solution
Raztopina sestoji iz sveže pripravljene raztopine, ki vsebuje 35 (± 2) g/l aktivnega klora (približno 1 M), ki ji je dodano 5 (± 0,5) g/l predhodno raztopljenega natrijevega hidroksida.
This consists of a freshly prepared solution containing 35 (± 2) g/l of active chlorine (approximately 1 M), to which 5 (± 0,5) g/l of previously dissolved sodium hydroxide is added.
Za pripravo raztopite 100 gramov litijevega hipoklorita, ki vsebuje 35 % aktivnega klora (ali 115 gramov, ki vsebuje 30 % aktivnega klora) v približno 700 ml destilirane vode, se doda 5 gramov natrijevega hidroksida, raztopljenega v približno 200 ml destilirane vode; nato se dolije destilirana voda do skupno 1 litra.
To prepare, dissolve 100 grams of lithium hypochlorite containing 35 % active chlorine (or 115 grams containing 30 % active chlorine) in approximately 700 ml of distilled water, add 5 grams of sodium hydroxide dissolved in approximately 200 ml of distilled water and make up to 1 litre with distilled water.
Raztopina natrijevega hipoklorita
Sodium hypochlorite solution
Raztopina sestoji iz sveže pripravljene raztopine, ki vsebuje 35 (± 2) g/l aktivnega klora (približno 1 M) in ki ji je dodano 5 (± 0,5) g/l predhodno raztopljenega natrijevega hidroksida.
This consists of a freshly prepared solution containing 35 (± 2) g/l of active chlorine (approximately 1 M) to which 5 (± 0,5) g/l of previously dissolved sodium hydroxide is added.
Izvede se postopek, opisan v splošnih navodilih, in nadaljuje, kot sledi: v erlenmajerici s prostornino 250 ml se 1 gram preskusnega primerka prelije s približno 100 ml raztopine hipoklorita (litijevega ali natrijevega hipoklorita) in temeljito pretrese, da se preskusni primerek omoči z raztopino.
Follow the procedure described in the general instructions and proceed as follows: mix approximately 1 gram of the test specimen with approximately 100 ml of the hypochlorite solution (lithium or sodium hypochlorite) in the 250 ml flask and agitate thoroughly in order to wet out the test specimen.
Erlenmajerica z vsebino se namesti v termostat za 40 minut pri temperaturi 20 ºC, pri čemer se jo ves čas ali vsaj v rednih časovnih presledkih pretrese.
Then heat the flask for 40 minutes in a thermostat at 20 ºC and agitate continuously, or at least at regular intervals.
Ker je raztapljanje volne eksotermen proces, je treba reakcijsko toploto pri tej metodi porazdeliti in odvajati.
Since the dissolution of the wool proceeds exothermically, the reaction heat of this method must be distributed and removed.
V nasprotnem primeru lahko pride do precejšnih napak zaradi začetka raztapljanja netopnih vlaken.
Otherwise, considerable errors may be caused by the incipient dissolution of the non-soluble fibres.
Po 40 minutah se vsebina erlenmajerice prefiltrira skozi predhodno stehtan stekleni filtrirni lonček in vsa preostala vlakna prenesejo v filtrirni lonček, tako da se erlenmajerica izpere z manjšo količino hipokloritnega reagenta.
After 40 minutes, filter the flask contents through a weighed glass-filter crucible and transfer any residual fibres into the filter crucible by rinsing the flask with a little hypochlorite reagent.
Na koncu se tekočina odsesa iz filtrirnega lončka, filtrirni lonček z vsebino pa posuši, ohladi in stehta.
Finally, drain the crucible with suction, dry the crucible with the residue, and cool and weigh them.
V homogenih mešanicah vlaken znaša interval zaupanja ± 1 za dobljene rezultate pri 95-odstotnem statističnem zaupanju.
On homogeneous mixtures of textile materials, the confidence limits for results obtained by this method are not greater than ± 1 for a confidence level of 95 %.

; then rinse thoroughly with cold water.
Med samim izpiranjem ali med posameznimi izpiranji se tekočina ne odsesava, temveč naj najprej odteče zaradi težnosti in šele nato odsesa.
