Standard sheet 1 (Figure D.1) Hybrid appliance inlet The outline marked with 3) shall be at a distance of (16,5 +0,5) mm from the engagement face at the bottom of the inlet. The distance from the engagement face at the bottom of the inlet to plane A-A may, however, be less elsewhere within the area marked with 1). Plane A-A need not necessarily be extended to the outline of area marked with 1). A rim which is slightly rounded on top is allowed around the recess if it has a thickness of at least 1,5 mm. Retaining devices or parts thereof may be within the area marked with 1). No other parts of the inlet may protrude beyond plane A-A. The height marked with 2): For appliance inlets arranged countersunk in the outer surface of equipment and if this surface is curved or inclined with respect to the axis of the appliance inlet, this dimension shall be not more than 17 mm; the minimum shall be determined by visual inspection. Dimensions to be checked by means of a gauge or 3D measurement. NOTE The sketches are not intended to govern design, except as regards the dimensions shown. Dimensions without tolerances are only recommendations.
D.2 Gauges D.2.1 Distance to the point of first contact This subclause of IEC TS 63236-1:2021 is not applicable. D.2.2 “GO” gauges for appliance inlets according to standard sheet 1 (Figure D.1) The gauge in Figure D.3 shall be inserted fully into the appliance inlet with a force not exceeding 60 N. The thickness of the gauge plate k, as well as the nominal values of the dimensions s and t of the handle and of the hole in the gauge plate, are left free, but the tolerances h7 and F8 shall be respected. The plane A-A of the inlet shall lie between planes B-B and C-C of the gauge. Then the gauge plate k shall be pushed over the handle to check the free area around the inlet opening. For appliance inlets according to standard sheet 1 (Figure D.1), the “GO” gauges described in Figure D.3 shall be inserted.IEC TS 63236-3  pdf download.
