106 SPN distincts apparaissent dans ces paires. 273 des 561 paires utilisent des SPN que WABCO attribue lui-même (516,096 et au-delà), nommés d'après ses propres documents ; les autres utilisent des SPN standard dont la signification est la même pour toutes les marques.
Lignes de cet équipementier dans l’échantillon gratuit. Le jeu de données ajoute les procédures ordonnées pour chaque paire, avec les estimations de coût et de main-d’œuvre lorsqu’elles sont connues et un nom de pièce lorsqu’une pièce est associée.
