TS ISO 15787

TS ISO 15787 is a technical product documentation standard concerned with how heat-treated ferrous parts are represented and how their final condition is indicated in technical drawings. Its focus is the consistent communication of the condition a part must have after heat treatment, helping design, manufacturing, and inspection parties use the same language.

What “final condition” means in drawing practice

Heat treatment is used to change properties such as hardness, strength, ductility, and microstructure in ferrous materials. For that reason, a drawing must often communicate more than shape alone; it must also identify the required post-treatment state. In general technical documentation practice, this kind of standard supports a clear way to show that information so the intended manufacturing condition is not left ambiguous.

Why this subject matters in practice

• It applies to heat-treated parts made from ferrous materials.
• It covers the manner of presenting final-condition information in technical drawings.
• It supports clear and systematic communication of the post-heat-treatment state.
• It is relevant wherever heat treatment is used to achieve specified material states such as hardening, tempering, or annealing.

Standards in this area bridge material engineering and drafting practice. Two parts with the same geometry may behave very differently after heat treatment, so the final condition must be identified accurately to align production intent with inspection expectations. This record shows that TS ISO 15787 addresses that topic and that the edition is withdrawn, while the underlying drafting issue remains a meaningful one in engineering documentation.
