The work of preparing International Standards is norm

17、ally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in t

18、he work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare

19、 International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some

20、 of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1833-11 was prepared by Technical Committee ISO/TC 38, Textiles. This first edition of ISO 1833-11 cancels and replaces Clause 10 of ISO 1833:19

31、ric acid, to determine the proportion of cellulose fibre, after removal of non-fibrous matter, in textiles made of mixtures of natural and regenerated cellulose fibres and polyester fibre. 2 Normative references The following referenced documents are indispensable for the application of this documen

32、t. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 1833-1, Textiles Quantitative chemical analysis Part 1: General principles of testing 3 Principle The cellulose fibre is dissolved ou

33、t from a known dry mass of the mixture, with 75 % (mass fraction) sulfuric acid. The residue is collected, washed, dried and weighed; its mass is expressed as a percentage of the dry mass of the mixture. The proportion of cellulose fibre is found by the difference. 4 Reagents Use the reagents descri

34、bed in ISO 1833-1 together with those given in 4.1 and 4.2. 4.1 Sulfuric acid, 75% (mass fraction). A suitable reagent can be prepared by adding carefully, while cooling, 700 ml of concentrated sulfuric acid ( 1,84 g/ml) to 350 ml of distilled water. After the solution has cooled to room temperature

35、, dilute it to 1 I with water. The concentration is not critical within the range 73 % to 77 % (mass fraction) sulfuric acid. 4.2 Ammonia, dilute solution. Dilute 80 ml of concentrated ammonia solution ( 0,880 g/ml) to 1 I with water. BS EN ISO 1833-11:2010ISO 1833-11:2006(E) 2 ISO 2006 All rights r

37、iven in ISO 1833-1, and then proceed as follows. To the specimen contained in the conical flask, add 200 ml of sulfuric acid per gram of specimen. Insert the stopper and shake the flask carefully to wet out the specimen. Maintain the flask at (50 5) C for 1 h, shaking the flask and contents gently a

38、t intervals of about 10 min. Filter the contents of the flask through the weighed filter crucible using suction. Transfer any residual fibres to the crucible by washing out the flask with a little more sulfuric acid. Drain the crucible using suction, and wash the residue on the filter once by fillin

39、g the crucible with a fresh portion of sulfuric acid. Do not apply suction until the crucible has drained under gravity or stood for 1 min. Wash the residue successively several times with cold water, twice with dilute ammonia solution, and then thoroughly with cold water, draining the crucible usin

40、g suction after each addition. Do not apply suction until each washing liquor has drained under gravity. Finally, drain the crucible using suction, dry the crucible and residue, then cool and weigh them. 7 Calculation and expression of results Calculate the results as described in the general instru

41、ctions of ISO 1833-1. The value of d is 1,00. 8 Precision On a homogeneous mixture of textile materials, the confidence limits of the results obtained by this method are not greater than 1 for the confidence level of 95 %.
