Indian Standard

SPECIFICATION FOR LEATHER FOR BOXING GLOVES

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 2 January 1970, after the draft finalized by the Leather Sectional Committee had been approved by the Chemical Division Council. 0.2 The Sports Goods Sectional Committee while formulating standards on sports goods as a whole, requested Leather Sectional Committee to take up the formulation of standards on leather for sports goods. This standard is expected to assist the tanners to offer a suitable leather to the manufacturers of boxing gloves and to help the Sports Goods Export Promotion Council and various Quality Marking Schemes of State Governments in selecting a material of choice controlled by the conditions of national sports or the export market needs. 0.3 Leather becomes effectively mildew-resistant without adversely influenc- ing its non-toxic character by treating it with O-1 percent of sodium tri- chlorophenate or o-phenylphenate based on dry weight of the finished leather. Any other fungicide or a combination of fungicides which is known to be harmless to skin in small dosages may be substituted, but the optimum dosage should be worked out by experiment.

0.3.1 Extreme caution is to be exercised since the excess dosage of fungi- cides is harmful and often causes chaffing, irritation and dermatitis. TO arrive at the optimum dosage of effective and non-toxic fungicides, the method given in Appendix A may be followed. 0.4 The requirements given in this standard are based on authentic test data on indigenous samples received by courtesy from Sports Goods Export Promotion Council and others. The following laboratories took part in the inter-laboratory test scheme whose technical collaboration is gratefully acknowledged:

a ) Central Leather Research Institute, Madras b ) College of Leather Technology, Calcutta c ) National Test House, Calcutta

0.5 The Committee took note of the present practice in the trade which made use of vegetable tanned leather for the palm portion of the gloves but felt the use of the same should be discouraged in view of the better material got by other tannages.

, IS : 5597 - 1970

method prescribed in B-3. At the end of the prescribed period, the sample may have growths of mildew as defined below:

Vigorous - Entire surface of the-leather covered with mildew in test period.

Moderate - Three-fourths of the surface of leather covered with mildew in test period.

Slight - One-half of the surface of leather covered with mildew in test period.

Very slight - One-fourth of the surface of leather covered with mildew in test period.

Negative - No growth of mildew in test period.

A-I.2 Treat the leather with fungicides to such an extent that no growth of mildew is just observed on the leather; the efficiency of the fungicide treatment is best judged by the performance of the treated leather following the procedure given in A-1.I when subjected to mildew growth test and improvement made till no growth is obtained.

APPENDIX B ( Clause 4.6.1 )

TEST FOR MILDEW RESISTANCE

B-1. OUTLINE OF THE METHOD

B-l.1 Untreated leathers as well as those leathers treated with agents to give mould resistance are smeared, sprayed or swabbed with mixed spore suspension of species of mould found in tanned leathers and the resistance of such leathers to the growth of moulds is evaluated.

B-l.2 Conditions prescribed for sampling in this test method correspond to the conditions to which the leathers are subjected, in use and normal storage.

B-2. SAMPLE

B-2.1 The test pieces shall be treated as follows.

B-2.1.1, The samples of one portion are kept for seven days at 45f2”C in an oven with forced air circulation and leached by drumming for three hours in about 30 times their weight of water at 27f2”C (see IS: 196-1966” ). The leached samples are then drained and blotted.

*Atmospheric conditions for testing ( revised ).

IS : 5597 - 1970

B-2.1.2 The second portion of the sample is tested as received.

B-3. APPARATUS

B-3.1 Containers for Keeping Tests Pieces - Any suitable glassware which can be conveniently stoppered, for example, jars and desiccators glass tanks with greased covers to preclude loss of water vapour during the test, may be used. The vessel may contain water at the bottom or cotton wool or clean sand previously saturated with boiling water. This is done to obtain 100 percent relative humidity at approximately 30°C.

NOTE - The same vessel shall not be used for simultaneous testing of samples treated with different fungicides.

B-3.2 Incubator - one capable of maintaining 45f2”C with forced air circulation and another capable of maintaining 30&2”C.

B-4. STANDARD MIXED SPORE SUSPENSION

B-4.1 Standard* mixed spore sand suspension of the culture of species of moulds to be used in the test. With each batch of such a suspension a list showing the organisms incorporated therein as well as the last date before which the culture is to be used shall be furnished.

B-5. PROCEDURE

B-5.1 Cut four strips of 50 x 10 mm from the treated samples ( see B-2.1 ), dampen with sufficient water for about 5 minutes, smear, spray or swab with mixed spore suspension and then subsequently suspend them above a free water surface in a suitable covered vessel as described under B-3.1.

B-5.2 Viability Control - Simultaneously, tests shall be carried out with control samples of leather not treated with fungicide.

B-5.2.1 If this untreated material fails to show any abundant growth of the test organism, the test shall be considered inconclusive and whole test be repeated.

B-5.3 Incubation - Incubate the samples for 30 days at 30f2”C and 95 to 100 percent relative humidity in the incubation cabinet ( see B-3.2 ) kept in the dark.

B-5.3.1 The samples shall be examined at frequent intervals, at least once a week and the date of the first appearance of mould growth shall be noted.

“At present only sand spore suspension of species of mould usually found in tanned leathers are supplied by the Central Leather Research Institute, Madras.

IS : 5597 - 1970

C-3. PROCEDURE

G3.1 Soak 50 x 75 mm leather test piece, cut ( see 3.2.1 of IS : 5868-1970* ) with occasional

out from sampling portion flexing for 2 hours in the

perspirant solution. Preheat large, rectangular, heat-resistant glass jars with lids at 70°C and hang the leather test pieces on glass rod within the jars containing 100 ml of water at 70°C. Seal the jars tightly with lids and place in an oven set at 70°C for 48 hours. Remove the leather test pieces and air-dry them at room temperature. Repeat the test with the control piece using distilled water in place of the artificial perspiration to check for any adverse effect due to heat ( 70°C) and humidity ( 100 percent). Use a planimeter for measuring the area of the leather before and after testing.

C-4. EVALUATION OF RESULTS

C-4.1 Examine the test piece subjected to perspiration for any change in area, stiffness or discolouration. Examine the control piece for any ‘change in area, stiffness or discolouration.
