IS 3806:1966 is the Indian Standard (BIS) for wooden beaters. This Indian Standard lays down the specification for material, dimensions, workmanship, and testing of wooden beaters, which are hand tools primarily used for compacting earth, foundry sand, or for agricultural operations.

Both specify manual tools for compacting construction materials; BS 1339 was broader, including cast iron rammers.

Tamper, T-Handle, Earth
Specifies a hand tool for the same purpose (soil compaction), but dictates a very different T-handle, all-steel design.
Key Differences
≠Material Specificity: IS 3806 is exclusively for wooden beaters, specifying Indian timber species. International counterparts like the withdrawn BS 1339 included cast iron, and modern functional equivalents like A-A-59424 specify all-steel construction.
≠Standard Obsolescence: IS 3806 remains an active standard, whereas equivalent prescriptive standards for simple hand rammers in many western countries (e.g., BS 1339) were withdrawn decades ago, reflecting a shift to mechanical compaction and performance-based specifications.
≠Design and Construction: The Indian Standard specifies a simple rectangular block head with a handle fitted through a central mortise. The US federal specification A-A-59424 details a fabricated tool with a flat steel plate base welded to a steel pipe upright and a T-handle.
Key Similarities
≈Core Function: Both the IS standard and its international counterparts define a manually operated tool for compacting unbound materials like soil, hardcore, or concrete in construction.
≈Basic Ergonomics: All designs, whether wood or metal, incorporate a heavy base (head) to provide impact force and a long handle to allow a user to operate it from a standing position.
≈Durability Requirement: Both IS 3806's specification of dense, hard timber and international standards' use of cast iron or steel reflect a common requirement for a robust tool that can withstand heavy, repetitive impact on a construction site.
≈Weight Class: The specified minimum weight of 4.5 kg in IS 3806 is comparable to the typical weight of hand rammers and tampers defined in other historical or functional standards, which often centered around the 10 lb (4.5 kg) class.
