Key Differences
≠IS 620 permits a wide range of indigenous Indian timbers (e.g., Sal, Mango, Teak) alongside international species. International standards like DIN 5131 or BS 3823 focus almost exclusively on high-performance species like Hickory and Ash.
≠International standards like DIN 68340 provide a detailed grading system (e.g., Classes E, S, A, B) with varying levels of permissible defects and grain slope. IS 620 has a more monolithic set of requirements without such granular quality grades.
≠The requirements for slope of grain are generally more stringent in high-grade international standards. For example, DIN 68340 Class E requires a slope not steeper than 1 in 40, whereas IS 620 specifies a more lenient 1 in 25 for striking tool handles.
≠US standards (e.g., ANSI B107.410) are increasingly performance-based, specifying tests for handle-head adhesion, overstrike durability, and impact resistance, whereas IS 620 is prescriptive, focusing on material and manufacturing requirements to achieve quality.
Key Similarities
≈All standards emphasize the critical importance of straight grain and correct orientation of the grain parallel to the major axis of stress, especially for striking tools, to maximize strength and user safety.
≈There is a universal requirement across all standards for handles to be free from major strength-reducing defects such as decay, insect damage, splits, cross-grain, and large or unsound knots.
≈All standards recognize the importance of using seasoned wood and specify a target moisture content range (typically 10-15%) to ensure dimensional stability and prevent the handle from loosening in the tool head.
≈A smooth, splinter-free surface finish is a common requirement in all standards to ensure user comfort and prevent hand injuries.
