1. Description of Product
Plywood is a panel formed of three or more layers of veneer glued together, usually with the grain of adjacent veneers running at right angles to each other (Ref: IS 707). IS 303:1989 (third revision) covers the requirements of different grades and types of plywood used for general purposes. As per IS 303:1989 (third revision), Plywood for general purposes shall be the following two grades, depending upon the bond strength developed by the adhesive used for bonding the veneers:
a) Boiling water resistant or BWR Grade b) Moisture resistant or MR Grade
Moreover, plywood for general purposes shall be classified into three types, namely, AA, AB and BB based on the quality of the two surfaces, namely, A and B in terms of general permissible defects. The type of plywood, shall, therefore, be designated by the kind of surfaces of the panels The better quality surface shall be called ‘face’ and the opposite side shall be called ‘back’.If the face and the back are of the same quality, they are not distinguished. The type of plywood shall denote first the quality of face followed by the quality of back. For example, Type AA shall have both surfaces of quality A, Type AB shall have face of quality A and the back of quality B and Type BB shall have both the surfaces of quality B.

PROPOSED GROUPING GUIDELINES FOR IS 303:1989
1. The plywood for General purposes may be grouped under two categories as shown below:
Group Grade & Type 1 BWR-AA, BWR-AB and BWR-BB 2 MR-AA, MR-AB and MR-BB
2. Since Grade-BWR Type- AA being the most superior grade, for covering all grades & types under the licence, BWR-AA variety may be drawn for Independent Testing. 3. However while considering grant of licence /inclusion of additional variety, it will be ensured that the applicant/licensee has got the complete manufacturing and testing facilities for varieties to be covered in the licence. 4. During operation of the licence in an operative period, BO shall ensure that all designation & grades covered in the licence are tested in factory and drawn for Independent testing on rotation. The above grouping guidelines may be considered for finalization by CMD.
