Evidence of our claim that IS: 303 is not a marine plywood
Indian Standard IS 303 : 1989

PLYWOOD FOR GENERAL PURPOSES SPECIFICATION (Third Revision)

FOREWORD

The Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards on 21st December 1989, after the draft finalized by the Wood Products Sectional Committee had been approved by the Civil Engineering Division Council.

Indian Standard Specification for commercial (common) and moisture proof plywood (tentative) (IS : 303 : 1951) published in 1951. This was subsequently revised in 1960 and 1975. This is the third revision of the standard and in this revision, care has taken to utilize the depleting wood resource judiciously.

In the second revision of the Standard, namely IS 303 : 1975 provided for four grades of plywood based on the type of adhesive used and ten types of plywood depending upon the visual features of face and back thus making a total of as many as 40 classes of plywood.

In this revision, BWR and CWR grades are deleted and WWR is replaced by moisture resistant or MR grade with temperature of water under normal atmospheric pressure in which test piece shall be immersed brought down to 60 + / - 2 0 C from 70 + / - 2 0 C. This revision deletes face “A” and “D” quality of plywood, and retains face “B” and “C” now renamed as “A” and “B” thereby permitting in all 3 types of plywood based on appearance.

QUALITY ASSURANCE

‘ISO Certification’ V/S ‘IS Certification’
ISO certificate is meant for judging the procedural standards of the company. It does not approve the quality of the product. To determine the quality of the product IS Standard Certification is essential. And we are proud to say that Kitply Gold confirms it.

Our pride. Our identity. – The Kitply Stripes
Stripes are an integral part of any plywood and Kitply is no exception. Kitply stripes are the most distinctive feature of Kitply Gold. We flitch stripes in our own units and then join the veneer by Fisher and Ruckle, a state-of-art machinery making the face veneer one single piece. There is no plywood in the market having such a distinct proof of originality. So, all you have to do is identify the Kitply stripes and buy yourself an original plywood.
