Bitumen felts may be of different types depending upon the raw material used and their construction. IS 1322 : 1993 'Specification for bitumen felts for water proofing and damp-proofing (fourth revision )' and IS 7193 : 1993 'Specification for glass fibre base coal tar pitch and bitumen felts (first revision )', cover bitumen felts of hessian based and glass fibre base respectively. The above standards require, amongst other requirements, detailed testing of each of these products. Various methods of test relating to each product for determination of physical properties have been included in the separate standards. All types of felts have to satisfy some common essential physical requirements for which methods of test are same. A series of standards covering methods of test have, therefore, been formulated to cover the determination of various physical requirements of bitumen felt. This standard covers determination of binder content. Other parts of this standard are as follows: Part Part Part Part Part Part 1 Breaking strength test 2 Pliability test 3 Storage sticking test 4 Pressure head test 5 Heat resistance test 6 Water absorption test 'The composition of the technical committee responsible for the formulation of this standard is given in Annex A. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test, shall be rounded off in accordance with IS 2 : 1960 'Rules for rounding off numerical values ( revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. IS 131Ui ( Part 7 ) : 1993 Indian Standard BITUMEN BASED FELT PART 7 METHODS OF TEST DETERMINATION OF BINDER TEST 4 APPARATUS 1 SCOPE This standard (Part 7 ) covers method for the determination of binder content in bitumen felts by Soxhlet apparatus. 2 REFERENCES The Indian Standards listed below are necessary adjuncts to this standard: 4.1 The apparatus ( see Pig. 1 ) shall consist of normal Soxhlet capable of holding extraction thimble and flask of 500 ml capacity with ground glass joint to fit the Soxhlet. 4.2 A suitable electric mentle heater with regulator or a gas ring. 4.3 Extraction thimble made of single layer filter paper (which shall not allow any filler material to pass through) of dimension generally of 25 mm dia and 80-100 mm long and properly shaped. IS No. Title Trichloroethylene ( third revision) technical 245 : 1988 1840 : 1961 4911 : 1986 Benzene, reagent grade Glossary of terms relating to bituminous water-proofing and damp-proofing of buildings 4.4 Solvent 4.4.1 The solvent shall be benzene ( see IS 1840 : 1961 ) or trichloroethylene ( see IS 245 : 1988 ). 4.4.2 Size of Sample One test piece of 15 em x 10 em of the bitumen felt shall be taken for the test. 3 TERMINOLOGY For the purpose of this standard, the definitions given in IS 4911 : 1986 shall apply. ASSEMBLED SQXHLET FIG. CONDENSER 1 TYPICAL SOXHLBT ApPABATUS SYPHON 1 IS 13826 ( Part 7 ) : 1tt3 4.5 Procedure 4.5.1 The thimble shall be dried at l~oC to 110°C, then cooled in a desiccator and wel~hed. The bitumen felt sample shall be weighed nearest to 0·1 g and is folded and put in the thimble. The sample of the felt shall be CU~ into pieces, if necessary, to be accommodated In the thimble. 4.5.2 About 400 ml of the solvent shall be taken into the properly cleaned and dried flask and the soxhlet shall be fitted over the flask. Care should be taken that the ground glass fittings are perfect and there is no leakage. 4.5.3 After fixing the reflex condensor, heat shall be applied at the bottom of. the flask slowly. 'The heating should be adJuste~ to ensure a steady reflux of 60-70 drops per IW nute falling from the end of the condensor on the middle of the extraction thimble. It is to be observed that at least three cycles of siphoning of solvent is taken place in 10 minutes. on the dry sample by means of the following formula: B where = MJ MM 1 2 X 100 M 1 ~ weight of the sample in g, and M 1 = weight of the recovered hessian base with filler in g. In order to, correct for any fine material present in the solution at the end of the test, the solvent shall be distilled off, the residue cooled down and weighed and a representative portion of it (between 2 and 3 g) treated with the solven t and filtered through a sintered silica filtering crucible or filter paper. 4.6.2 In the case of materials containing high filler content the whole of the solution at the end of the test should be filtered or centrifugalled. The binder content B sh~ll be calculated on the dry sample by the following formula: 4.5.4 Refluxing shall be continued until extraction is completed. This may be understood when the solvent siphoned to the flask is clear. 4.5.5 The thimble with extracted hessian and filter shall be taken out and dried to constant weight at 100°C-IIOoC. B = M1 ( MM1 M a ) x 100 percent by mass where M 1 = mass of sample in g; M 2 = mass of recovered hessian base in g; and M = mass of filler, if any, reclaimed from 3 4.6 Calculation ".6.1 The binder content B shall be calculated the extracted bitumen solution either hy centrifuging or by decantation after settlement. 2 IS 13826 ( Part 7 ) : 1993 ANNEX A ( Foreword) COMMITTEE COMPOSITION Water-Proofing and Damp-Proofing Sectional Committee, CEO 41 Chairman PROF M.
