FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Paper and Pulp Based Packaging Sectional Committee had been approved by the Chemical Division Council.

This is one of the series of methods of test standards on composite cans and is based on Composite Can and Tube Institute Standard Testing Procedure CT-107, May 1981 published by the Composite Can and Tube Institute, United States of America.

The composition of the committee responsible for formulation of this standard is given in Annex A.

In reporting the result of a test or analysis made in accordance with this standard, if the final value, observed or calculated, is to be rounded off, it shall be done in accordance with IS 2 : 1960 ‘Rules for rounding off numerical values ( revised )‘.

IS 13975 : 1994

AXIAL ( END-TO-END ) COMPRESSION STRENGTH OF COMPOSITE CANS, TUBES

AND CORES - METHOD OF TEST

1 SCOPE

This standard prescribes procedure to measure the axial ( end-to-end ) compression strength of composite cans, tubes and cores by leading to failure.

2 REFERENCES

The Indian Standard listed below is necessary adjunct to this standard:

IS No. Title

lG!f( Part 1 ) : Metallic materials - Veri- fications of static uniaxial testing machines : Part 1 Tensile testing machines ( second revision )

3 APPARATUS

3.1 Compression Testing Machine

Having flat upper and lower platens which are held rigidly parallel during testing, permitting movement in a vertical direction only. The speed of the moving platen shall be ( 13 f 3 mm ) per minute unless otherwise specified. The speed-shall be the actual rate of travel of the platen while under the load. The com- pression machine shall be accurate to _1= 1 percent of the minimum crushing load used. The compression machine shall be calibrated as per IS 1828 ( Part 1 ) : 1973. If errors are found greater than & 1 percent, then a cali- bration curve shall be constructed and used to correct the indicated load before reporting.

4 PROCEDURE

4.1 Condition the samples to equilibrium mois- ture content at 27 f 2°C prior to test. Condi-

tioning would, however, be impractical for samples covered with, or impregnated with, materials highly resistant to penetration.

water vapour

4.2 When testing the compressive strength of empty .csmposite cans, samples are normally used wrth both ends fitted with closures exactly as if the cans were filled for their intended use. Composite cans also may be tested with one or both ends open; the applicable condition should be specified in the testing report.

4.3 Tubes and cores shall be tested in 100 mm lengths. The samples shall be cut by a method which will keep end surfaces parallel to each other.

4.4 When testing, insert the samples in the compression testing machine at the center between the two platens, and apply the com- pression load until the load becomes constant or drops. Record to the nearest calibrated unit on the load indicator.

5 RESULT

The following details shall be reported:

1) Identification of samples.

2) ‘Conditioning history and/or moisture content.

3) Wall thickness of samples.

4) Inside and/or outside diameters of samples.

5) If testing composite cans, indicate the number of ends applied to the samples.

6) Maximum load to the nearest calibrated unit on the load indicator.
