ASTM D882 Test Guide: Tensile Testing for Plastics
TensileAlways use a dual-blade specimen cutter to guarantee perfectly smooth, nick-free parallel edges; even a microscopic nick will act as…
-
ASTM D903 Test Guide: Peel Testing for Adhesives
PeelAlways discard the first 25mm of peeling data from calculations; adhesive failure must reach steady-state equilibrium before capturing valid averages.
-
ASTM E238 Test Guide: Shear Testing for Metals
ShearMeasure both the pin outer diameter and hole inner diameter to the nearest 0.01mm to document exact clearance values.
-
ASTM E290 Test Guide: Bend Testing for Metals
BendAlways grind or deburr the sheared longitudinal edges of the bend specimen to a smooth radius to prevent invalid edge-tear…
-
ASTM E466 Test Guide: Fatigue Testing for Metals
FatigueThe active gauge area must be polished longitudinally to a mirror finish (down to 0.2-micron roughness) to eliminate circumferential machining…
-
ASTM E517 Test Guide: Testing for Metals
FormabilityEnsure the specimen edges are polished completely free of blanking burrs; even minor edge roughness skews the transverse width extensometer…
-
ASTM E643 Test Guide: Formability Testing for Metals
FormabilityAlways apply a standardized, high-pressure grease lubricant uniformly to the punch apex to guarantee pure, friction-free stretch-forming dynamics.
-
ASTM E646 Test Guide: Formability Testing for Metals
FormabilityAlways verify that the linear regression regression coefficient (R^2) exceeds 0.995; a lower value indicates invalid data collection or localized…

ASTM E8 Test Guide: Tensile Testing for Metals
TensileAlways configure the closed-loop controller to run under automated strain-rate control (0.015 mm/mm/min) during the critical yield envelope.
