Rules for the Measurement and Inspection of Hardwood and Cypress
Provides rules for measuring timber volume, but uses a fundamentally different unit (board foot) and methodology.

Sawn timber — Measurement of features
Provided an international method for measuring sawn timber dimensions, similar to EN 1309-1, forming the basis for volume calculation.
Key Differences
≠IS 2377 provides pre-calculated volume 'tables' for lookup, whereas modern international standards (e.g., EN 1309-1) specify a 'method' or 'procedure' for measurement and calculation, expecting users to perform the simple multiplication.
≠The Indian standard is a standalone document for volume. International standards are typically part of a comprehensive system that also covers dimensional tolerances (e.g., EN 1313-1), moisture content, and strength grading.
≠IS 2377 is exclusively metric, calculating volume in cubic metres (m³). US standards, like the NHLA rules, use the 'board foot' as the primary unit of volume, which is based on a mix of inches and feet.
≠International standards like EN 1309-1 often specify measuring dimensions at a reference moisture content (e.g., 20%), as timber dimensions change with moisture. IS 2377 does not specify moisture content, basing its tables on nominal dry sizes.
Key Similarities
≈The fundamental principle behind all standards is the same geometric formula: Volume = Length × Width × Thickness. The IS code simply pre-calculates the results.
≈The primary purpose is consistent across all standards: to establish a standardized and repeatable method for quantifying the volume of sawn timber for commercial trade and inventory management.
≈All standards in this context specifically apply to 'cut' or 'sawn' timber (e.g., planks, battens, boards), not round logs, wood-based panels, or other forms of wood products.
≈The final volume in all cases is determined based on the physical, linear dimensions of the timber piece, rather than by weight or other properties.
