FOREWORD

This Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards, afier the draft finalizedby the Footwear Sectional Committee had been approved by the Chemical Division Council.

Rubber boots are moulded or assembled footwear that are made of rubber in combination with cotton fabric.Rubber knee boots are also known popularly in the trade as gum boots. The upper portion of this footwearextends almost up to knee height and its sole is designed to prevent slipping. These boots are meant for generalprotection of feet and are mostly used in slushy and water-logged areas. There are also special uses of the saidkind of boots in petrol pumps and other uses in oily area where such products need to have oil resistivity propertytoo.

In this standard two types of boots are being specified to cover the usage in general condition (Type 1) and alsofor use in areas where products are frequently in contact with oil and grease (Type 2).

This standard is being aligned with IS 5557:1999 ‘Safety rubber boots for testing’ and other requirements arebeing similar group of footwear.

For the purpose of reference to any Indian Standard for the purpose of evaluation, the ambit of current andamended standard only will be attracted.

The composition of the Committee responsible for formulation of this standard is given at Annex E.

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 or analysis, shall be rounded off in accordance withIS 2:1960 ‘Rules for rounding off numerical values (revise~’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.

METHOD OF DETERMINATION OF FLEXING ENDURANCE FOR VAMP AND UPPER

B-1 The machine has an adjustable stationary part,provided with grips of 25 mm across for holding oneend of each of the test pieces in a fixed position and asimilar but reciprocating part for holding the other endof each test piece.

The reciprocating part is arranged so that the motionis in the direction of and in the same plane as the centreline between grips. Its travel is adjusted so that thetwo sets of grips approach each other to a distance of57 mm. The eccentric which actuates the reciprocatingpart is driven by a constant speed motor to give300 * 10 flexing cycles/rein for vamp.

The motor should have sufilcient power to flex at leastsix and preferably twelve test pieces at a time. The testpieces should be arranged in two equal groups so thatone group is being flexed while the other group is beingstraightened, thus reducing the vibration in themachine. The grips shall hold the test pieces firmlyand enable individual adjustment to be made to thetest pieces.

B-2 TEST PIECE

The test pieces shall have the dimension shown inFig. 4 where the size and the style of the footwearpermits. Test pieces are to be taken out from one articleof footwear. In other cases take three or hvo test pieceswhichever is possible, from one article of footwear.Test pieces are to be cut from the vamp of the upper.Care to be taken to ensure that the test pieces are cutout cleanly from the sample material.

B-3 TEST PIECE FOR FLEXING TEST

B-3.1 Procedure

Fold the test piece symmetrically about its major axisso that the rubber surface is outwards. In the foldedcondition insert one tapered end into the f~ed centralgrip and push in untir sample touches the grip pins.Tighten this freed grip. Take out the correspondingmovable grip to its fidlest extent; insert the test pieceand pull flat and tighten the grip. It is recommendedthat clips may be used to keep the edges together duringthe insertion of the test piece in the grips, but theirremoval is essential before the flexing commences.

NOTE — The test piece should not be under tension.

B-4 EXPRESSION OF RESULTS

A complete to and fi’omovement of the grip is countedas one flex cycle. Report the number of cycles requiredto start cracking. The flex cycle maybe determined byusing a trip counter operated by one of the movable grips.

NOTE — The materials shall be chemically pure.

C-6 SIZE OF TEST PIECES

For the soles and heels of the boots, the test piecesshall be 1to 3 cm3in volume and of a uniform thicknessof 2.0 + 0.2 mm.

For the upper part of the boots, a test piece of 1 to 3cm3 in volume shall be prepared after removal of thefabric, the area depending on the thickness, but neitherthe length nor the breadth shall be greater than 50 mm.

C-7 APPARATUS

A stoppered glass bottle or tube shall be used, itsdimensions being such that, the test pieces remaincompletely immersed in the immersion liquid, and arefreely exposed at oil surfaces without restraint.

C-8 PROCEDURE

C-8.1 Three test pieces shall be used. Each test pieceshall be weighed in air to the nearest milligram(mass, m}) and then in distilled water at the standardlaboratory temperature (mass, ml) care being taken toensure that all air bubbles are removed.

C-8.2 The test pieces shall be blotted dry with filterpaper or with a textile fabric that does not deposit lint,and then placed, suitably separate~ in a glass containerwith a volume of the immersion liquid at least 15 timesthe combined volume of the test pieces and sutllcientto keep them totally immersed.

C-8.3 The container shall be stoppered, kept at therequired temperature and the rubber shielded from lightduring the test.

Only test pieces of the same vulcaniz.ate shall be placedin any one container. If the density of the rubber isless than that of the liquid, a means shall be providedfor holding the test pieces completely below the surfaceof the liquid.

C-8.4 At the end of the immersion period, surplusimmersion liquid shall be quickly wiped from the testpieces with filter paper or (textile fabric which does notdeposit lint). Each test piece then being placedimmediately in a tared and stoppered weighing bottle;and its mass in air determined (mass, mj) to the nearestmilligram. The test piece shall then be removed fromthe bottle and immediately weighed in distilled water(mass, mJ at the standard laboratory temperature. Thetime for each transference of the test pieces tier removalfrom the immersion liquid shall not exceed 30s.

C-9 CALCULATION

The change in volume shall be calculated as follows:

~= (m, -m,) (m, -m,)xloo

% - m3

where

ml= initial mass of test pieces in air,

mz= initial mass of test pieces in water,

m,= mass of the treated rubber test piece in air,and

md= mass of the treated rubber test pieces in water.

The results of the three test pieces shall be averaged.

The maximum time between the date of manufacture,where known, and testing shall be 3 months. Wherethe date of manufacture is not known, the maximumtime for testing shall be 6 weeks from the date ofreceipt.

Attach the loaded scale pan to the gripthrough a light spring. The total mass of the grip,spring loaded scale pan and attachments shall be takenas the applied load. Obtain either the load required tocause separation of 25 mm/min graphically byselecting various loads or for a known or specifiedload. Determine the rate of separation. Repeat theprocedure on the separate plies from the face ply tothe centre ply. Test the second specimen commencing
