IS 2209:1976 is the Indian Standard (BIS) for laminated wood products - specification. This standard prescribes the requirements for materials, dimensions, manufacture, and testing of vertical type mortice locks intended for use on timber doors. (Note: The title 'Laminated Wood Products' provided in the input is likely a database mismatch; IS 2209 strictly covers Mortice Locks).
Lays down the requirements for laminated wood products, including glued laminated timber, covering materials, manufacturing, and properties.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Maximum Lamination Thickness | 40 mm for conifers; 50 mm for hardwoods. | Generally 45 mm for both softwoods and hardwoods. | EN 14080:2013 |
| Lumber Moisture Content at Gluing | 12 ± 3% (i.e., 9% to 15%). | Shall not exceed 16%, and the difference between adjacent laminations shall not exceed 5 percentage points. | ANSI A190.1-2022 |
| End Joint Type and Slope | Specifies scarf joints with a slope not steeper than 1 in 12 for high-stress zones. | Primarily specifies finger joints. If scarf joints are used, a slope of 1 in 10 (tension) or 1 in 8 (compression) is typical. | ANSI A190.1-2022 |
| Clamping Pressure (Softwoods) | 0.7 to 1.0 MPa. | 0.7 to 1.0 MPa (100 to 150 psi). | ANSI A190.1-2022 |
| Cyclic Delamination Test Limit (Exterior Use) | Max 5% delamination for WBP adhesive type. | Max 5% for Southern Pine; Max 10% for other softwood species. | ANSI A190.1-2022 |
| Glue Line Shear Strength (Dry) | Varies by timber species group (e.g., 8.8 MPa for Group A). Requires ≥80% wood failure. | Varies by species; e.g., for Douglas Fir, must meet published values (~8.6 MPa or 1250 psi). Requires ≥80% wood failure. | ANSI A190.1-2022 |
