5 ISO core chamber No.3一Dimensions and tolerances
ISO core chamber No.3 (see Figure 5) is designed mainly for bent valves for which the valve mouth is too short to receive a long core.
The dimensions of the core chamber shall be in accordance with Table 3 and the tolerances of the core pin head in accordance with Figure 2.
6 ISO core chamber No.4一Dimensions and tolerances
ISO core chamber No. 4 (see Figure 6) is designed mainly for bent valves for which the valve mouth is too short to receive a long core; it is for used only with ES01, ES02, ES03, FR02, FR03, FS01, FS02, GS01, and DF01 (see ISO 9413).
