Indian Standard SPECIFICATION FOR

CONDENSED MILK CANS

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 30 November 1981, after the draft finalized by the Metal Containers Sectional Committee had been approved by the Marine, Cargo Movement and Packaging Division Council.

0.2 The Standards of Weights and Measures Act, 1976, specifies the net mass of condensed milk to be packed for retail sale as 200 g, 400 g, I kg and there after in multiples of 1 kg. The most popular size of the condensed milk pack in this country has been 400 g whereas 200 g pack is yet to be introduced in the market. A need was, therefore. felt to standardize this pack size to help the industry in achieving a uniform size of the pack.

1. SCOPE

1.1 This standard prescribe the requirements of round tinplate containers for packing 400 g of sweetened condensed milk.

2. TERMINOLOGY

2.1 For the purpose of this standard, the definitions given in IS : 1394 - 1973* shall apply.

3. CAPACITY AND DIMENSIONS

3.1 Capacities and diameter of the can shall be as under:

Nominal capacity - 300 ml ( 400 g )

Nominal diameter - 74 mm

Trade size t - 301 x 302.25

____ *Glossary of terms relating to metal containers trade ( secmd revisior~ ). tThe trade sizes are included here because the trade is currently more familiar with

these. When the trade becomes familiar with metric nomenclature, the trade size will be deleted.

3

IS : 9991 - 1981

Internal diameter - 74.07 & 0.1 mm

Punch plug diameter -- 73.76 & 0.05*

Gross lidded capacity - 300 i 9 ml

3.1.1 The gross capacity of the can shall be measured by the method as detailed in Appendix A of IS : 6093 - 19717.

4. MATERIAL

4.1 The milk can’s body and ends shall be made from cold-reduced electrolytic tinplate of nominal thickness 0.22 mm. The minimum tin coating on the tinplate shall conform to Grade E 5.6 / 5.6 of IS : 1993 - 19731.

4.1.1 Tolerances on tinsheet thickness and tincoating mass shall be as per IS : 1993-19741.

5. MANUFACTURE

5.1 Each component shall be made from a single piece of tinplate.

5.2 The body of the can shall be single seemed. The side seam of body shall be formed as shown in Fig. 1.

_~__~~~~ ~ *This deviation must not be confused with the manufacturing tolerances. The

deviation is given to allow different sizes of punch plugs to be used within a limited range and is for the guidance of the manufacturer only.

5.4.1 In case of internal lacquering, the tincoating thickness may be relaxed and shall be specified by the purchaser.

5.5 External Protection - Cans shall be externally plain or printed to customer design as agreed to between the purchaser and the can manufacturer.

6. SAMPLJNG
