4 General 4.1 As a general principle, all glassware shall be drawn as if it were non-transparent (opaque), according to ISO 128-34:2001, Clause 15. 4.2 In terms of observation of calibration, font and pointer, the outer glassware shall be drawn as a transparency.
7 Thin walls 7.1 Drawing of wall thickness When drawn in section, thin walls shall be represented, in spite of their real wall thickness, by lines with a thickness of at least twice that used for visible outlines (see Figures 5, 6, 7, 8, 9 and 10).
6 Special glassware indications 6.1 Interchangeable conical ground joint Interchangeable conical ground joints conforming with the requirements of ISO 383 shall be designated in the manner described therein. Accordingly, no detailed dimensioning of that portion and no indication of the surface finish are required. An example of a code identification for interchangeable conical ground joints is shown in Figure 3.
