SPECIFICATION FOR EQUIPMENT FORDETERMINATION OF SHRINKAGE FACTORS

0. FOREWORD0.1 This Indian Standard was adopted by the Indian Standards Institutionon 20 January 1982, after the draft finalized by the Soil Engineering andRock Mechanics Sectional Committee had been approved by the CivilEngineering Division Council.0.2 The Indian Standards Institution has already published a series ofstandards on methods of testing soils. It has been recognised that reliableand intercomparable test results can be obtained only with standard testingequipment capable of giving the desired level of accuracy. The SectionalCommittee has, therefore, decided to bring out a series of specificationscovering the requirements of equipment used for testing soils toencourage its development and manufacture in the country.0.3 The equipment covered in this standard is used in the apparatus fordetermination of shrinkage factors of soils covered in IS : 2720 ( Part VI )-1972*.0.4 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, expressingthe result of a test or analysis, shall be rounded off in accordance withIS : 2-196Oj_. The number of significant places retained in the rounded offvalue should be the same as that of the specified value in this standard.

1. SCOPE1.1 This standard covers the requirement of equipments for the apparatusused for determination of shrinkage limit, shrinkage ratio, shrinkage indexand volumetric shrinkage of soils.2. DIMENSIONS2.1 Dimensions and tolerances of different equipment shall be as detailedin Fig. 1 to 6 and in 4.6. Except where tolerances are specificallymentioned against the dimensions, all dimensions shall be taken as nominaldimensions and tolerances as given in IS : 2102-1969: shall apply.

5.1.1 The equipment may also be marked with the IS1 CertificationMark.NOTE The use of the ISI Certification Mark is governed by the provisionsof the Indian Standards Institution ( Certification Marks ) Act and the Rulesand Regulations made thereunder. The ISI Mark on products covered by anIndian 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 operatedby the producer. IS1 marked products are also continuously checked by IS1 forconformity to that standard as a further safeguard. Details of conditions underwhich a licence for the use of the IS1 Certification Mark may be granted to manu-facturers or processors, may be obtained from the Indian Standards Institution.8
