Indian Standard

SPECIFICATION FOR TAPIOCA FLOUR, COTTON TEXTILE INDUSTRY

( First Revision )

0. FOREWORD

0.1 This Indian Standard ( First Revision ) was adopted by the Indian Standards Institution on 8 November 1977: after the draft finalized by the Textile Sizing and Finishing Materials Sectional Committee had been approved by the Textile Division Council.

0.2 While finalizing this standard, the Committee decided to prescribe the requirements of viscosity separately by using Redwood Viscometer and Brookfield Viscometer. Since the relation between the values of viscosity observed by using these two methods is yet to be established, the require- ments prescribed in this respect are tentative only.

0.3 To familiarize the industry with International System of Units ( SI Units ), the basis SI Units as well as the recommended SI Units for use in the textile industry are given in Appendix A.

0.3.1 Standards of Weights and Measures Act, 1976 also stipulates use of SI Units.

0.4 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, express- ing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard covers tapioca flour used in ( cotton ) textile sizing and finishing.

*Rules for rounding off numerical values ( seuiseJ ).

IS : 2033 - 1977

2. REQUIREMENTS 2.1 Physical-The tapioca flour for textile industry shall meet the following physical requirements:

Particle size Residue through 150 ’ micron IS sieve, 1 per- 1 IS : 4706-1968* cent, Max

Cold water 9.5 percent, Max solubles

Viscosity at 75°C 40 seconds, Min J NOTE 1 -The requirements mentioned above in respect of viscosity are on

tentative basis only. NOTE Z-The method for preparation of paste for viscosity determination shall

be as follows when Redwood Viscometer is to be l!sed: Weigh 4.0 g of the dry material.

200 ml water, with continuous stirring. Add this to a beaker containing Weigh the beaker and the stirrer

along with its contents. Keep the beaker in a boiling water-bath and cover with a plastic plate. Stir this with the paddle type mechanical stirrer at a speed of 45 to 50 rev/min. After one and a half hours weigh the contents along with the stirrer. Add sufficient water to compensate for the loss of

water during cooking. Cook it for another 10 minutes and determine the viscosity of the pastr at t!lr rcq,lircd t?mprrat*trr :IGry suitable viscometcr.

2.3 If the original test specimens are analyzed as such in order to eliminate the time-consuming oven-drying, the observed mass should be corrected for moisture content while calculating the results.

3. PACKING

3.1 The tapioca flour ( since hygroscopic in nature ) should be packed in paper or polyethylene-lined jute bags. Bags preferably conforming to IS : 7406-1974t, IS : 8115-1976: or 8117-19564 may serve the purpose.

4. MARKING

4.1 Each package shall be marked with the name and net mass of the contents (kg), name or tlade-mark of the manufacturer and date of packing.

4.1.1 The package may also be marked with the ISI Certification Mark.

NOTE-The use of the IS1 Certification Mark is governed by the provisions of the Indian Standards Institution (Certification Marks ) Act and the Rules and Regulations made thereunder. The IS1 Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-defined system of inspection, testing and quality control which is devised and supervised by IS1 and operated by the producer. IS1 marked products are also continuously checked by IS1 for conformity to that standard as a further safeguard. Details of conditions under which a licence for the use of the IS1 Certification Mark may by granted to manufacturers or processors, may be obtained from the Indian Standards Institution.

5. SAMPLING

5.1 Procedure for sampling of tapioca flour for carrying out tests given in 2.1 and 2.2 shall be as given in IS : 4662-197711 unless otherwise specified in the contract.

*Methods of test for edible starches.

IS : 2033 - 1977

5.2 Starch content and particle size shall be tested on individual samples and the remaining characteristics on composite samples.

5.3 Criteria for Conformity

5.3.1 Where the value specified is maximum, mean + 0.5 range shall not exceed the specified value.

5.3.2 Where the value specified is minimum, mean - 0.5 range shall not fall below the specified value.

ESTIMATION OF PETROLEUM HYDROCARBON EXTRACTABLE MATTER

B-l. PROCEDURE

B-l.1 Weigh accurately about 5 g of the test sample in a thimble and mix with 5 g of purified coarse sand previously extracted with petroleum hydrocarbon solvent ( 60 to 80°C bp ). Place a piece of absorbent cotton in the top portion of the thimble to distribute the solvent as it drops on the sample. Transfer the thimble to the Soxhlet extractor. Take adequate quantity of petroleum hydrocarbon in a tared Soxhlet extraction flask and assemble the Soxhlet extraction apparatus. Heat on a water-bath or electric hot plate at such a rate that the solvent will drop from.the conden- ser on the centre of the thimble at the rate of at least 150 drops/min. Keep the volume of the solvent fairly constant by adding enough of petroleum hydrocarbon to make up for any loss due to evaporation. Continue extraction for 2 hours. Remove the thimble from the apparatus after the extraction and distill the excess of’solvent leaving about 25 ml of the solution in the Aask. Transfer the solution to a tared lOO-ml beaker. Evaporate the solvent in the beaker on a steam-bath followed by heating in an oven maintained at 100” f- 3°C for 30 minutes.
