Introduction

Marine plywood is a specially manufactured plywood product designed for applications where the material may be exposed to moisture, humidity, wet conditions and demanding environments.

IS 710:2010 – Marine Plywood – Specification was the Indian Standard specifying requirements for materials, manufacture and performance of marine plywood intended for applications such as the construction, repair and maintenance of marine and river craft, pontoons and similar applications.

Marine plywood requires controlled manufacturing, suitable timber and veneers, appropriate adhesive systems and satisfactory performance against applicable tests.

For manufacturers seeking BIS certification, understanding the applicable Indian Standard, product requirements, testing procedures, manufacturing controls and documentation is important.

Current standard update: IS 710:2010 has been revised to IS 710:2024 – Marine Plywood – Specification (Third Revision). BIS's implementation guidelines stated that 26 December 2024 was the last date for implementation of the revised standard, after which the previous standard was to stand withdrawn.

About Marine Plywood

Marine plywood is manufactured using multiple layers of wood veneers bonded together with suitable adhesive.

It is intended for applications where plywood may encounter:

High humidity
Moisture
Wetting and drying cycles
Marine environments
River environments
Temperature variations
Demanding structural applications

The BIS draft product manual describes marine plywood as plywood used in the construction, repair and maintenance of marine and river craft and capable of withstanding conditions involving changes in temperature, humidity and alternate wetting and drying.

Marine plywood is commonly associated with applications such as:
