The crash cushion head is defined by the manufacturer and accepted by the test house performing the test.
NOTE 2 If no agreement is reached between the manufacturer and the test house regarding the definition of the crash cushion head, the test can be performed according to the manufacturer's definition and a note should be added to the test report outlining the diverging points of view.

5.6 Families of crash cushions A family of crash cushion models shall be derived from a single parent crash cushion once the latter has been successfully tested to this standard.
A reduced matrix of tests shall be completed for the other family members in accordance with Tables 4 to 9. The models in the family cover a range of performance classes, width and taper angles.
Provided that the models in the family: a) are assembled from the same set of components; b) have the same product name; c) have the same working mechanism for the system and for the components, the family, specified by the drawings of all the models, can be tested as a single product with multiple performance levels. If the tests specified by the family test matrix are passed, the crash cushion is accepted as a multiple performance product, i.e. each model is accepted in the relevant performance class. All the cushions in the family shall be of the same type, i.e. all redirective or all non-redirective. If the parent crash cushion has the minimum taper angle/width and belongs to the highest performance class, the test matrix is the one shown in Table 4, 5, 6 or 7, depending on the highest velocity of the family.
