Engineering drawing on base engineering is described as Graphical Communications in various school and college books. Technical Product Documentation (TPD) is the name given to the whole arena of design communication by ISO. The full title of TPD is technical product specification – methodology, presentation and verification. This includes the methodology for design implementation (engineering drawing, diagrams and three dimensional modeling), verification (metrology and precision measurement), technical documentation, electronic formats and controls and related tools and equipment.
New published drawing as on ISO standard will write on TPD heading, it is given the designation: ISO XXXX:Year. The ‘XXXX’ stands for the number allocated to the standard and the ‘Year’ stands for the year of publication. The standard number bears no relationship to anything; it is effectively selected at random. If a standard has been published before and is updated, the number is the same as the previous number but the ‘year’ changes to the new year of publication. If it is a new standard it is given a new number. This twofold information enables one to determine the version of a standard and the year in which it was published. When an ISO standard is adopted by the UK, it is given that when any ISO standard is published that is relevant to TPD, it is automatically adopted and therefore rebadged as a British Standard.
In the term ‘engineering drawing’ will be used throughout because this is the term which is most likely to be understood by manufacturing engineering students, for whom the book is written. However, readers should be aware of the fact that the more correct title as far as standards are concerned is TPD.
