We associate to every central simple algebra with involution of orthogonaltype in characteristic two a totally singular quadratic form which reflectscertain anisotropy properties of the involution. It is shown that thisquadratic form can be used to classify totally decomposable algebras withorthogonal involution. Also, using this form, a criterion is obtained for anorthogonal involution on a split algebra to be conjugated to the transposeinvolution.
