TS 7621

TS 7621 is a terminology standard for packages of yarns and intermediate products. Within textile machinery and accessories, it establishes a common vocabulary for naming the package forms used for yarn and intermediate textile materials, supporting clearer communication in production, quality control, cataloguing, and technical documentation.

Package forms and the role of terminology

In textile practice, a package may be named according to the carrier on which the material is wound and the way it is built. The distinction between wound on a spindle and wound without a spindle is a basic one because it affects how the package is handled, stored, unwound, and fed into later processing stages. The standard focuses on consistent naming, not on defining a new manufacturing process.

What the standard covers

• Terminology for packages of yarns and intermediate products.
• Naming distinctions for packages wound on a spindle and packages wound without a spindle.
• Common technical language for the textile machinery and accessories field.
• An EQV edition aligned with ISO 5238-1:1982.

From a general technical perspective, terminology standards matter because different names for the same package type can create confusion across suppliers, machine makers, and users. TS 7621 helps organize the core terms used to describe yarn packages and intermediate product packages in a consistent and practical way.
