Indian Standard

METHOD OF MEASUREMENT AND EXPRESSION OF THE DIMENSIONS OF PAPER SACKS

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 28 December 1978, after the draft finalized by the Paper and Flexible Packaging Sectional Committee had been approved by the Marine, Cargo Movement and Packaging Division Council.

0.2 Differences in the method of measurement and expression of the dimensions of paper sacks and the materials from which they are manu- factured occur both nationally and internationally. The object of this standard is to overcome these differences to the mutual benefit of customers, vendors in the national and international trade.

0.3 The paper sacks are used mostly for the export packaging of cement, fertilizers, chemicals and other powder materials.

0.4 This standard is based on ISO/DP 6591 Paper of dimensions and expression of sizes, issued by the zation for standardization ( IS0 ).

sacks - Measurement International Organi-

1. SCOPE

1.1 This standard specifies the method of measurement and expression of the dimensions of empty paper sacks.

2. DEFINITIONS

2.1 For the purpose of this standard, the following definitions in addition to those given in IS : 9028-1978* shall appIy.

NOTE - Unless otherwise specified, references are to external dimensions.

2.1.1 Length of Sack - Distance, measured at the middle perpendicular to the bottom, between the outermost edges of the sack lying flat.

2.1.2 Width of Sack - Distance, measured at the middle parahel to the bottom, between the outermost edges of the sack lying flat.

*G,lossary of terms relating to paper sacks.

3

IS : 9042 - 1978

2.13 Width of Gusset - Distance, measured at the middle, between the external creases of a gusseted sack when unfolded.

2.1.4 Width of Bottom - Total dimension of bottom, measured at the middle parallel to sack length.

2.1.5 Width of V&e, g - Internal dimension of valve, measured at the middle parallel to sack length.

2.1.6 Length of V&e, f ( Pasted Sucks Onl?, ) - Distance, measured at the middle parallel to bottom, between the outermost edge of the sack and the innermost edge of the valve/sleeve minus half of bottom width.

2.1.7 Length of Valve Sleeve, k - Longitudinal dimension of internal or external sleeve, parallel to bottom.

2.1.8 Width of Valve Sleeve, v - Inner measure of the sleeve cross the bottom.

2.1.9 Sewing Line Distance, n - Distance of the sewn closure from sack edge, measured at the middle perpendicular to closure.

2.1.10 Length of Turn-Over, p - Length of flap on a turn-over bottom sack, measured at the middle perpendicular to closure.

3. EQUIPMENT

3.1 Ruler or instrument graduated in millimetres, and capable of measur- ing dimensions of the sack to an accuracy of 1 mm.

4. SAMPLING

4.1 The saniple sacks shall be representative of the lot, and shall be selected at random as specified in 3 of IS : 1060 ( Part 1 )-1966”.

5. PROCEDURE

5.1 Condition the sack under atmospheric conditions of 27 f 2°C and 65 f 5 percent RH, in accordance with IS : 1060 (Part I )-1966”. The sack shall be so suspended that the air has free access to all surfaces until equilibrium has been reached with the conditioning atmosphere. This equilibrium is considered to be reached when the sacks, measured at intervals of not less than 6 hours do not differ by more than 1 mm between the last two measurements. Usually 1 day for sacks without, and 3 days for sacks with a moisture barrier will be sufficient. Place the sack on a flat horizontal surface and smooth out any wrinkles. Measure the dimensions at the measuring points indicated in 7 for the type of sack

concerned. Measure at least 10 sacks to an accuracy of not less than I mm.

6. CALCULATION AND EXPRESSION OF RESULTS

6.1 Calculate the dimensions as the mean of the determinations, and express them in millimetres to the nearest 1 mm.

7. DESIGNATION OF SACKS

7.0 The sacks shall be described by the successive indication of their type ( open mouth-sewn-flat sack, valved-pasted-sack, etc ) and their dimensions as specified in 7.1 and 7.2.
