Tables for volumes of cut sizes of timber
1967 Edition

IS 2377 defines the scope for volume tables applicable to timber sections with a fixed thickness of 10 mm and widths ranging between 40 mm and 120 mm. It provides standardized volume data for lengths varying from 30 cm up to 450 cm, enabling accurate measurement without manual computation. The volume is calculated as Volume (m³) = Thickness (m) × Width (m) × Length (m), where thickness is fixed at 0.01 m, width varies from 0.04 m to 0.12 m, and lengths are between 0.3 m to 4.5 m.

An excerpt from the volume tables illustrates volumes for various lengths and widths, rounded as per IS 2-1960 for consistency.

This section details the volume tables for timber cut sizes based on the metric system, aligned with IS 1331-1966 specifications. The primary formula for volume computation is provided along with sample tabulated data for timber with a 10 mm thickness. It emphasizes the importance of adhering to rounding protocols from IS 2-1960 and highlights the practical use of these tables in procurement and material estimation.

Clarifies key terms related to timber dimensions and volume calculations under IS 2377. It reiterates the fixed thickness of 10 mm and the width and length ranges. Includes example calculations demonstrating volume determination for a specific timber size and length, supported by tabulated volume data. It also underscores the necessity of rounding volumes as per IS 2-1960.

Summarizes essential requirements including fixed thickness, width range, and length variation. Details the volume calculation formula and explains unit conversions necessary for accurate volume measurement in cubic meters. Provides sample data extracts from the volume tables and outlines typical applications in inventory management and construction.

Presents the volume tables for timber with a constant thickness of 10 mm and widths from 40 mm to 120 mm, including lengths from 30 cm to 450 cm. It reiterates the volume calculation formula and supplies sample table data. Notes on rounding volumes and instructions for interpolation or calculation for other sizes are also included.

Explains the rounding procedures as mandated by IS 2-1960, which are applied to all volume figures in the tables. It describes rounding thresholds and the precision level maintained (up to five decimal places). The section also displays the foundational formula for volume computations and provides sample volume data to illustrate the application of rounding rules.

Discusses the practical use of IS 2377 volume tables in estimating timber quantities for standard sizes. It covers the alignment with IS 1331-1966 sizes and emphasizes the benefit of using these tables for rapid and accurate volume estimation, essential for procurement, inventory control, and construction planning.

Details the specified thicknesses, widths, and lengths covered by the standard, including variations beyond the primary 10 mm thickness. Provides sample volume data for different size categories and explains the methodology for converting dimensions into volume via the standard formula. Notes on unit conversions and volume tabulation are also included.

Highlights key considerations for volume calculations under IS 2377, reiterating the fixed thickness and width ranges, length coverage, and rounding practices. It reinforces the use of the given formula and volume tables to avoid manual errors and enhance consistency in timber volume estimations.

Contains annexed material including the main formula for volume calculation, sample volume tables for 10 mm thickness timber, and notes on rounding according to IS 2-1960. It also offers practical insights for estimating timber volumes accurately for procurement, costing, and stock management.
