ASTM E436 testing covers the drop-weight tear test (DWTT) on ferritic steels with thicknesses between 3.18 and 19.1 mm (0.125 and 0.750 in.). Results may be used to determine the appearance of propagating fractures in plain carbon or low-alloy pipe steels (yield strength less than 825 MPa). A drop-weight tear test (DWTT) of API X80 steel was conducted at various temperatures according to the ASTM E436 [2]. The DWTT and specimen are schematically shown in Fig. 3 (a) with the a central 45° pressed notch of 5.08 mm depth. A DWTT testing machine (DWTT-100F) with the maximum energy capacity of 100 kJ was used.

1.1 This test method covers drop-weight tear tests (DWTT) on ferritic steels with thicknesses between 3.18 and 19.1 mm (0.125 and 0.750 in.). mm. 1.2 The values stated in SI (metric) units are to be regarded as standard. No other units of measurement are included in this standard. The drop-weight tear test (DWTT) is a widely used test to evaluate fracture resistance [1,2] and it is commonly known that fracture behavior is well characterized by the DWTT because the thickness of a DWTT specimen is the same as that of a pipe [3,4].

Prince Rupert's drops. Prince Rupert's drops (also known as Dutch tears or Batavian tears) [1] [2] are toughened glass beads created by dripping molten glass into cold water, which causes it to solidify into a tadpole-shaped droplet with a long, thin tail. These droplets are characterized internally by very high residual stresses, which give rise to counter-intuitive properties, such as .OCAS's Battelle drop weight tear test allows investigating and characterising brittle and ductile fracture resistance in full thicknes samples
