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.5 Sections 5.1 Small sections Small sections may be blackened, conforming with ISO 128-50:2001, Clause 8, provided that the distance between their outlines on the actual drawing is not larger than 3 mm. If larger, the section shall be hatched. For thin-walled parts, see 7.1. 5.2 The combination of different materials Parts of different materials, such as glass-metal seals which are fused together and shown in section, shall be hatched differently (see Figure 2). 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. 6.2 Interchangeable spherical ground joint Interchangeable spherical ground joints conforming with the requirements of ISO 641 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 spherical ground joints is shown in Figure 4. 7 Thin walls dasaut 0001 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 Figures5, 6, Z, 8, 9 and 10].
