Civil and structural engineers use the exact masses and section moduli derived from JIS G 3193 to calculate load-bearing capacity. A 2% deviation in flange thickness might lead to a 5–8% deviation in moment of inertia. that feed into safety calculations.
Measurements are typically taken along the center line. Accessing the PDF jis g 3193 pdf
: The current version (JIS G 3193:2019) is modified based on the international standard ISO 7452:2013 to reflect Japanese transactional practices. Key Specifications in JIS G 3193 Title: JIS G 3193: The Backbone of Standardization
Tolerances vary based on the width and the nominal thickness of the plate. For example, a plate under 1.25 mm thick and under 1600 mm wide typically has a tolerance of ±0.16 mm. Q2: How does JIS G 3193 compare to ASTM A6/A6M
