DETERMINATION OF RELATIVE DENSITY

A-O. GENERAL

A-O.1 For the purpose of this standard, the relative density of the material is the ratio of the mass of a given volume of the material to that of an equal volume of distilled water, the temperature of both the material and the water being 27C.

A-l. APPARATUS

A-l.1 Pyknometer ( Hubbard Type ) - See Type 6 of IS: 5717-1970*.

*Specification for pyknometer.

5

IS : 1440 - 1980

A-2. PROCEDURE

A-2.1 Clean, dry and weigh the bottle and the stopper. Fill with water at a temperature of about 25C, introduce the stopper and keep it in a water bath at 27C for 15 minutes. Wipe off all adhering water from the surface with a soft, clean and dry cloth and weigh it again. Empty the bottle, clean and dry and repeat the operation with the material filled in it.

A-3. CALCULATION

Relative density at 27C = Ec 1

where

M, = mass in g of the relative density bottle filled with the material at 27X!,

M = mass in g of the dry relative density bottle, and

Ml = mass in g of the relative density bottle filled with distilled water at 27C.

APPENDIX B

[ Clause 3.2, and Table 1, Sl No. (ii) ]

TEST FOR PERFORMANCE

B-P. APPARATUS

B-l.1 Stamp Pad - It shall consist of two detachable parts, namely, body and cover. The body shall consist of a wooden base about 4 cm thick made of two concentric steps, the lower step being about 12 cm in diameter and l-5 cm thick and the upper step being about 10 cm in diameter and 2.5 cm thick. The base shall be plane so that it does not wobble on a level surface. On the upper layer shall be mounted a thick layer of good and strong felt pad covered by means of a,soft but strong ( preferably woollen ) cloth such that the cloth and the pad soak the ink readily and uniformly and withstand the high pressure of metal stamp. The thickness of the pad complete with cloth shall be not less than 2 cm. The pad shall be attached to the wooden base with the help of a brass ferrule about 2-5 cm high which shall be secured to the base by means of brass wood-screws around the circumference.

6

IS : 1440 - 1980

B-l.2 Metal Stamp - The engravings on the type face shall be sufficiently deep and neat to yield clear impressions on paper.

B-1.3 India Rubber Pad--At least O-5 cm in thickness. The surface of the pad shall be even, without any depressions or ridges.

B-2. PROCEDURE

B-2.1 Soak in sufficient quantity of ink on a clean and dry metal stamp pad. Ink the type face of a clean and dry metal stamp by pressing it evenly on the inked pad with moderate pressure and make a series of impressions on a white sheet of paper placed on India rubber pad. Observe the number of sharp and uniformly intense impressions that can be obtained after one inking of the stamp. Carry out a control test using exactly similar stamp pad, stamp, paper, and an equal quantity of an approved sample of the ink.

B-2.2 Repeat the process of inking the metal stamp and producing impress- ions on paper ten times with the material. On the eleventh time, again ink the metal stamp and after producing five impressions on paper, observe the condition of the type face of the stamp and the last stamp impression produced.

R-2.3 The material shall be considered satisfactory if:

a) the number of clear and distinctly intense impressions produced (see B-2.1 ) is not less than 95 percent of similar impressions produced by the approved sample, and

b) in the test under B-2.2 there is no filling of the closed portions or designs and no impressions other than those determined by the engraving on type face are produced and also there is no excessive deposit of ink.

APPENDIX C

[ CZause 3.2, and Table 1, SZ No. (iii) and (iv) ]

TEST FOR PERMANENCE AND SMUDGINESS

C-l. TEST SPECIMENS

C-l.1 Procedure -Take a few strips of 60 gsm bond paper. Make five impressions with a metal stamp as prescribed in B-2.1 on each sheet. The impressions shall be clear and of equal intensity.

7

IS : 1440 - 1980

C-l .2 Smudginess - Exactly four minutes after making the stamp impress- ions, rub the inked impression lightly with a thumb. The impression shall have no tendency to smudge.

C-l.3 Fastness to Saline Water - Take another strip with stamp impress- ions and dip it into a beaker containing sodium chloride solution (approxi- mately 10 percent m/v ) for one hour at room temperature. The ink shall be considered fast to saline water if impressions remain clear without any noticeable spreading of ink or loss of intensity.

C-l.4 Fastness to Organic Solvents - Take two fresh strips and dip one in denatured spirit ( see IS: 324-1959* ) and the other in petroleum ether ( bp 60C ) for one hour. The ink shall be considered fast to organic solvents if the impressions remain clear without any noticable spreading of ink or loss of intensity.

C-l.5 Fastness to Dilute Acetic Acid -Take another strip and dip it for one hour in dilute acetic acid ( 5 percent m/m ) at room temperature. The ink shall be considered fast to dilute acetic acid if the impressions remain clear without any noticeable spreading of ink or loss of intensity.

D-l.7 Each sample container shall be sealed air-tight after filling, and marked with details of the material as prescribed in 5.2 and the date of sampling.

D-l.8 Samples shall be stored in such a manner that the temperature of the material does not vary unduly from ambient temperature.

D-2. SCALE OF SAMPLING

D-2.1 Lot -All the containers in a single consignment of the material drawn from a single batch of manufacture shall constitute a lot. If a consignment is declared or known to consist of different batches of manufacture, the containers belonging to the same batch of manufacture shall be grouped togetherand each such group shall constitute a seperate lot.

D-2.1.1 Samples shall be tested from each lot separately for ascertaining the conformity of the material to the requirements of this specification.

D-2.2 The number of containers to be chosen from the lot shall depend on the size of the lot and shall be in accord,ance with Table 2.

D-2.3 These containers shall be chosen at random from the lot. In order to ensure the randomness of selection, reference may be made to IS : 490.5-1968*. In case this standard is not available, the following procedure may be adopted:

Starting from any container in the lot, count them as 1, 2, 3......up to r and so on where r is the integral part of N/n. Every rth container thus counted shall be withdrawn from the lot till the requisite number of containers is obtained.

D-3. TEST SAMPLES AND REFEREE SAMPLE

D-3.1 Preparation of Test Samples

D-3.1.1 Draw, with an appropriate sampling instrument, a small portion of the material from different parts of each container selected as prescribed in Table 2. The total quantity of the material drawn from each container shall be sufficient to make triplicate determination for all the characteristics given in 2 of the specification.

D-3.1.2 Thoroughly mix all portions of the material drawn from the same container. Out of these portions, a small but equal quantity of material shall be taken from each selected container and shall be well mixed together so as to form a composite sample of quantity sufficient to make triplicate determination for all the characteristics tested on the composite sample. This composite sample shall be divided into three equal parts, one for the purchaser, another for the vendor and the third for the referee.

D-3.1.3 The remaining portions of the material from each container (after a small quantity needed for formation of the composite sample has been taken out ) shall be divided into three equal parts. These parts shall be immediately transferred to thoroughly dried bottles which are then sealed air-tight with stoppers and labelled with all the particulars of samp- ling given in D-1.7. The material in each such sealed bottle shall constitute a test sample. These individual samples shall be separated into three identical sets of test samples in such a way that each set has a test sample representing each .container selected for sampling. One of these three sets shall be marked for the purchaser, another for the vendor and the third for the referee.

D-3.2 Referee Samples

D-3.2.1 Referee sample shall consist of the composite sample ( see D-3.1.2 ) and a set of test samples (see D-3.1.3 ) marked for this purpose and shall bear the seals of the purchaser and the vendor. This shall be kept at a place agreed to between the purchaser and the vendor and shall be used in case of a dispute between the two.

D-4. NUMBER OF TESTS

D-4.1 Test for performance and performance of the material shall be conducted on each of the sample constituting a set of test samples.

D-4.2 Tests for the determination of other characteristics mentioned in 3 shall be Conducted on the composite sample prepared under D-3.1.2.
