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. An example of an inner component and a jacket component glassware drawing is shown in Figure 1, in which the calibration is on the inner component and the jacket component is transparent in terms of observation.
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.
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).
7.2 Indication of diameter
Generally, the diameter dimension of a glass tube's thin walls shall be indicated according to
ISO 129-1:2018, 7.16.2. External diameter indication is shown in Figure 7 and internal diameter
indication is shown in Figure 8.BS EN ISO 6414 pdf download.
