59. The expert from the Netherlands introduced GRSP-72-33 on a possible solution to harmonize the three-dimensional H-Point Machine (3D HPM). He informed GRSP that the Working Party on General Safety Provisions already begun work with an ad hoc group supported by the expert from Spain. GRSP agreed to resume consideration on GRSP-72-33 and on the outcome of discussion of a group of interested experts (China, the Netherlands, Spain CLEPA and OICA) at its May 2023 session.

42. The expert from the Netherlands introduced a presentation (GRSP-71-08) on the background history of the work on harmonizing the three-dimensional H-point machine (3D H-point machine) that had ended. He urged that the work resume as soon as possible since the setting of the H-point stature was unclear and not consistent. He explained that Technical Services and laboratories accredited to ISO 17025, had met problems accrediting their test procedures, since the 3D H-point machines available on the market do not meet or cannot be calibrated according to the old specifications. GRSP agreed to restart the discussion on the lack of harmonization of the 3D H-point machine so as to reach a common understanding and solutions with the support of GRSP.
