TS 4634

TS 4634 is a standard concerned with plastic map sheet supports used in the production of maps and plans. In cartographic and drafting work, the backing or support layer matters because it helps the sheet remain flat, manageable, and suitable for precise graphic work. This makes the document relevant to the technical handling of map and plan media, not just to the map image itself.

The technical role of a plastic map sheet support

In general technical terms, a plastic support sheet may be used to back paper, film, or similar drafting media so the sheet stays flat and resists deformation during use. For maps and plans, where scale accuracy, edge stability, and legibility are important, the physical behavior of the support material becomes part of the production workflow. The choice of support can depend on the drafting method, storage conditions, and the intended use of the finished map.

What the standard covers

The stated scope covers plastic map sheets used in making maps and plans at any scale. That places the product class within general cartographic and technical drawing practice rather than a single map type. TS 4634 also references TS 635, TS 1663, and TS 3839, which situates it alongside related standards for pafta, drawing, and map production materials in the same technical environment.

• Focuses on plastic sheet supports used in cartographic and technical drawing work.
• Applies in the context of producing maps and plans at any scale.
• Addresses a product class linked to physical handling, flatness, and stability during use.
• Intended to be read together with related TS standards in the same document family.
