① Material status name and character code: H-hardness (Brinell hardness or Vickers hardness), suffix number indicates the hardness value; R- tensile strength, suffix number indicates the minimum tensile strength value; M- When manufactured, no mechanical properties are specified. See standard EN 1173-2008.
② A100、A11.3、A-gauge length
—Value when the gauge length A100 = 100 mm (d < 4mm).
—Value When the gauge length A = 5.65√So (d > 8mm); When the gauge length A11.3 = 11.3√So (4 < d ≤ 8mm), the minimum elongation value is 40%.
—Value when the gauge length A = 5.65√So (d > 8mm); When the gauge length A11.3 = 11.3√So (4 < d ≤ 8mm), the minimum elongation value is 20%.
—The value when the gauge length A11.3 = 11.3√So (4 < d ≤ 8mm). (See original 8.2Note2 for the above spacing)
Tables such as: softened, 1/8 hard, spring hard, etc., refer to the state of the material in the old standard
③ Or equivalent cross-sectional area for polygonal wire
