This standard was first published in 1966 and subsequently revised in 1977 by modifying grammages of various grades of paper to suit the requirements of the users and to economize on the cellulose raw materials. Depending on the users preferences during that time Grade 1was introduced under Type 2, Grade 2of Type 3was re]moved, and the requirement of porosity was included to take care of excessive pin holes in the base paper. ‘file quality of the base paper prescribed for making the following types of carbon papers is laid down in this standard: IS No. Title 1551:1991 Carbon papers for typewriter (second revision) 3450: 1994 Carbon papers, handwriting (seco/zd revision) 8075:1976 Back coated carbon papers for typewriter A scheme for labelIing environment friendly products known asECO-Mark has been introduced atthe instance of the Ministry of Environment and Forest (MEF), Governrnent of India. The ECO-Mark scheme would be adrninistered by the Bureau of Indian Standards (BIS) under the BISAct, 1986 asper the Resolutions No. 71 dated 2I February 199I and No. 425 dated 28 October 1992 published inthe Gazette of the Government of India. For a product to be eligible for marking with ECO logo, it shall also carry the 1S1Mark of BIS besides meeting additional environment friendly requirements. For this purpose, the Standard Mark of BIS would be asingle mark being acombination ofthe 1S1 Mark and the ECO logo. Requirements to be satisfied for aproduct to qualify for the BIS Standard Mark for ECO friendliness, will be optional; manufacturing units shall be free to opt for the 1S1 Mark alone also. This standard, therefore, incorporates environment friendly requirements for cover paper which is based on the Gazette Notification No. 455 dated 13November 1992 for paper as environment friendly products published in the Gazette of India. This standard contains clauses 4.4 a nd 5.1 which permit the purchaser to use his option for selection to suit his requirements. The composition of the Committee responsible for the formulation of this standard isgiven in Annex B. 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 accordance with IS 2: 1960 ‘Rules for rounding off numerical values (revise@’. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. 1S 3413:2004 Indian Standard BASE PAPER FOR CARBON PAPER— SPECIFICATION (Second Revision) 1SCOPE opacity.
