Note: In Table 1, the column “Tube body 1 inner diameter d and inner diameter of the neck between expanded portions 2 and 3” for Type BMN-1, Type BMN-2 and Type BMN-4 has confused superscripts in source-text extraction, and the specific tolerances require confirmation against the source standard (source-text extraction). The volumes of bulbs A, C and J of Type BMN-4 are listed in the source as 1.6, 2.1, 2.1, 2.1, 2.1, 2.1 (source-text extraction suspected misalignment), and the volume of bulb D is listed in the source as 11 (duplicate), requiring confirmation against the source standard (source-text extraction).
