What is ISO 6414 about?
ISO 6414 establishes rules and conventions for particular use with technical drawings on glassware, for example, laboratory glassware or glassware used in other technical fields.
Laboratory glassware can be utilised for high precision volumetric measurements.
Note: Optical parts are not, however, included herein.
Who is ISO 6414 for?
ISO 6414 on technical drawings for glassware is relevant to: 
- Glassware industry
- Mechanical engineers
Why should you use ISO 6414?
Technical drawing is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering. To make the drawings simpler to understand, people use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout.
Technical drawing is distinguished from the expressive drawing of the visual arts by providing precise communication in the preparation of a functional document. ISO 6414 helps you in achieving this by covering the rules and conventions of technical drawings on glassware. This will enable efficient flow of information within your organization.
