EN ISO 6414-2020 pdf free.Technical product documentation (TPD) — Technicaldrawings for glassware.
This document establishes rules and conventions for particular use with technical drawings onglassware, for example, laboratory glassware or glassware used in other technical fields.Optical parts are not, however, included herein.
The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document. For dated references,only the edition cited applies. Forundated references, the latest edition of the referenced document (including any amendments) applies.ISO 128-34:2001,Technical product drawings — General principles of presentation —Part 34: Views onmechanical engineering drawings
ISO 128-50:2001,Technical drawings —General principles of presentation — Part 50: Basic conventionsfor representing areas on cuts and sections

ISO 383, Laboratory glassware — Interchangeable conical ground jointsISO 641, Laboratory glassware — Interchangeable spherical ground joints
ISO 4793,Laboratory sintered (fritted) filters — Porosity grading, classification and designation.
ISO 10209,Technical product documentation — Vocabulary —Terms relating to technical drawings,product definition and related documentation.
For the purposes of this document, the terms and definitions given in ISO 10209 apply.
As a general principle,all glassware shall be drawn as if it were non-transparent (opaque).according to ISO 128-34:2001, Clause 15.
In terms of observation of calibration, font and pointer, the outer glassware shall be drawn as atransparency.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 interms of observation.Small sections may be blackened, conforming with ISO 128-50:2001,Clause 8, provided that thedistance between their outlines on the actual drawing is not larger than 3 mm. lf larger, the sectionshall be hatched.For thin-walled parts, see 7.1.Parts of different materials, such as glass-metal seals which are fused together and shown in section,shall be hatched differently (see Figure 2).Interchangeable conical ground joints conforming with the requirements of IS0 383 shall be designatedin the manner described therein. Accordingly, no detailed dimensioning of that portion and noindication of the surface finish are required.An example of a code identification for interchangeableconical ground joints is shown in Figure 3.EN ISO 6414 pdf download.
