Indian Standard

IS : 9055 - 1979

SPECIFICATION FOR ONE TIME CARBON PAPER

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 2 March 1979, after the draft finalized by the Inks and Allied Products Sectional Committee had been approved by the Chemical Division Council.

0.2 One time carbon paper has various end uses such as in teleprinter rolls, interleaving of plies, computer stationery and invoice sets. It is expected that this standard will fulfil the requirements of such users.

0.3 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 accord- ance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard prescribes the requirements and the methods of sampling and test for one time carbon papers.

2. TERMINOLOGY

2.1. For the purpose of this standard, the dtfinitions given in IS : 4395- 19677 shall apply.

3. TYPES

3.1 The material shall be of two types as follows:

?Ve A - Single side, and

Type B - Double side.

*Rules for rounding off numerical values ( revised ). tGlossary of terms relating to inks and allied industries.

IS 1 9055 - 1979

4. REQUIREMENTS

4.1 Description - The carbon paper shall consist of tissue paper coated on one side or both, as required, with suitable carbon ink necessary to give the required copying qualities. The coating shall be smooth, uniform and free from smudginess and tendency to separate as flakes whexi in use. It shall have no tendency to offset or stain on normal handling when left in contact with copying sheets.

4.2 Carbon Work - The carbon work shall be well defined and clean. Light shall have no appreciable effect on the typed carbon work.

4.3 Base Paper - The base paper used for the manufacture of the material shall be machine glazed, machine finished or rag-free tissue provided the same does not have any physical defects, namely, pin holes, crease and other imperfections that would impair the performance of the finished product.

4.4 Size - The size of the carbon paper shall be as agreed to between the purchaser and the supplier. It may be in the form of sheets or reels as required.

4.5 The material shall also comply with the requirements given in Table 1 when tested by the methods prescribed in the appendices. Reference to the appropriate appendices is given in co1 5 of the table.

5. PACKING AND MARKING

5.1 Packing - Unless otherwise agreed to between the purchaser and the supplier 25 or 100 sheets shall be suitably packed. in a packet which may be either a folder or cardboard box. When more than 25 sheets are packed in a packet, a demarcation sheet of distinctive colour, of the size of carbon paper, shall be included after every 25 sheets.

4

ISt9055 - 1979

5.2 Marking - Each packet shall be marked with the following information:

a) Name and colour of the carbon paper;

b) Size of sheet/roll;

c) Name of the manufacturer and/or his recognized trade-mark, if any;

d) Batch number in code or otherwise to enable the lot of manufacture to be traced back from records; and

e) Date of packing.

5.2.1 The packets may also be marked with the IS1 Certification Mark.

NOTE - The use of the 1.51 Certification Mark is governed by the provisions of the Indian Standards Institution ( Certification Marks ) Act and the Rules and Regulations made thereunder. The IS1 Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-defined system of inspection, testing and quality control which is devised and supervised by ISI and operated by the producer. IS1 markrd products are also continuously checked by IS1 for conformity to that standard as a further safeguard. Details of conditions under which a liccncc for the use of the IS1 Certification Mark may be granted to manufacturers or processors, may be obtained from the Indian Standards Institution.

6. SAMPLING

6.1 The method of drawing representative samples of the material and the method of determining the criteria for conformity of the material to the requirements of this specification shall be as prescribed in Appendix C.

APPENDIX A [ Table 1, Items (i) and (ii) ]

DETERMINATION OF SUBSTANCE OF BASE PAPER AND MASS OF COATING

A-l. TEST PIECE

A-l.1 Condition a sheet of carbon paper as prescribed in A-2.1.1 and cut out a test piece measuring about 10.0 x 10.0 cm. Weigh it accurately.

5

IS : 9055 - 1979

A-2.1 Take a suitable quantity of carbon tetrachloride (gee IS: 718.1970* ) or a mixture of equal volumes of carbon tetrachloride and acetone ( see IS : 170-1966t ) in a beaker. Bring the contents to the boil on a water- bath and immerse the test piece into the boiling solvent until the tissue is clean. During this operation hold the test piece with forceps and agitate through the solvent. Repeat the operation with a fresh quantity. of this solvent, if necessary. After the coating has been removed dry the decoated paper, condition it ( see A-2.1.1 ) and weigh accurately.

A-2.1.1 Conditioning - Suspend the test piece in a conditioning chamber in which relative humidity of 65 f 2 percent and temperature of 27 f 1°C are maintained ( temperature should not vary by more than + 1°C in a given series of tests ) in such a way that conditioning atmosphere has free access to all its surfaces. The test piece shall be deemed to have reached equilibrium when the results of two consecutive weighings at an interval oi one hour do not differ by more than 0.4 percent of the total mass.

TEST FOR MANIFOLDING

B-l. PROCEDURE

B-l.1 Ordinary typing paper of substance 40 g/m2 (see IS : 1848-1971* ) shall be used for this test. A convenient size of sheet for this test is 9X20 cm. A first sheet and copy sheets with sheets of carbon paper shall be assembled in the usual way. The assembled sheets shall be inserted in the machine and the entire keyboard, both upper and lower case, shall be written twice over in unrelated order. The last copy sheet shall be examined for legibility. None of the characters shall be illegible.

C-l.2 Samples shall be protected from abnormal exposure to heat and light, and shall not be allowed to come in contact with any liquid.

C-l.3 Samples shall be touched as little as possible, and contact with sweated hands shall be avoided.

C-l.4 SampIes shall not be folded before testing.

C-2. SCALE OF SAMPLING

c-2.1 Lot - All the packets in a single consignment of the same size, same type and from the same batch of manufacture shall constitute a lot.
