  1. According to HOWMET, the tolerance of the “E” dimension was “+” in the prEN4074 version of the standard; so E : +0/+0.3, then became “-” in the issue of 2009 of the standard (E : -0.3/0).
    HOWMET considers “+0.3” in its definition in accordance with the initial tolerance value.
    It appears acceptable according to the auditor and it would be suitable to update the standard EN4074 accordingly.

    Sometimes, it is “+”, sometimes, it is “-“. However, a lot of ASNA standards, EN standards (EN4178 for instance) specify a height recess tolerance “+”. Thus, agreed from my side.
    Best regards,
    Julien
