With the experience gained by the use of corrugated fibreboard boxes over the years. depending upon the product to be packed into them. CHD 16 FOREWORD This Indian Standard ( Second Revision) ( Part 1 ) was adopted by the Bureau of Indian Standards on 31 May 1990 after the draft finalized by the Paper and Pulp Based Packaging Sectional Committee had been approved by the Chemical Division Council. the final value. bursting strength and water-proofing were varying and in some cases some of these requirements were not applicable. observed or calculated. This standard was first published in 1965 and was covering both solid fibreboard as well as corrugated fibreboard boxes. and Part 2 covering solid fibreboard boxes. it was felt that one single specification could not cover all the requirements of these boxes for variety of items. For the purpose of deciding whether a particular requirement of this standard is complied with. Part 1 covering CFB boxes only. The other requirements like compression strength. have been specified. by an d large. Depending upon the nature of the product to be packed into these boxes. puncture resistance. shall be rounded olf in accordance with IS 2 : 1960 'Rules for rounding off numcrica1 values (revised)'. if required. expressing the result of a test or analysis. The number of significant places retained in the rounded off value should be the same as that of the specified va luc in this standard. internal dimensions and manufacturing which arc applicable to all the boxes. only general requirements like bursting strength. the requirements like compression strength. Hence while revising this standard. it was revised in 1977 and split into two parts.
