27 J / -40 °C20 ft-lbs / -40 °F

1) Unless otherwise agreed, transverse impact testing according to EN 10025-6 option 30 will apply. For thicknesses between 6 - 11.9 mm, sub-size Charpy V-specimens are used. The specified minimum value is then proportrional to the cross-sectional area of the specimen compared to a full-size specimen (10 x 10 mm).

2) Other options are available after special agreement.
