TS 12502

TS 12502 is a vocational standard for the textile machine operator who works as an overlock operator, defining the occupation and the tools, equipment, and materials used in the role. In general technical terms, overlocking is the finishing of fabric edges with a seam that helps prevent fraying and gives a neater, more durable edge finish, which makes this job important in garment and textile production.

Technical role of the occupation

The standard focuses on what the occupation is, how the worker is identified, and which tools and equipment are associated with the task. Overlock machines are commonly used to trim and encase raw edges while forming a clean seam structure. In practice, the operator must coordinate fabric behavior, thread handling, seam formation, and production flow so the finished edge meets the needs of the product being made.

Place in textile and garment production

This standard reflects the work context found in textile and apparel enterprises and serves as a structured vocational reference for the occupation. Overlock operations are widely used for edge finishing, joining components, and improving the appearance and serviceability of sewn products, especially in garments and knitwear. The standard centers on the occupation’s definition and the equipment used, rather than setting out a detailed machine-setting manual or a step-by-step production method.
