TS ISO 4046-4

TS ISO 4046-4 is the part of the paper terminology series that focuses on paper and board grades and on converted products. Rather than specifying a material test or product performance limit, it provides the vocabulary used to describe and classify items in the paper and board sector, supporting consistent technical communication across the industry.

What the terminology covers

In paper and board practice, a “grade” is a way of identifying a product by its intended use, quality class, or market classification. “Converted products” are items made by further processing paper or board, such as cutting, folding, gluing, printing, or forming them into finished goods. This distinction matters because the same base material can appear in very different forms and applications, from printing and writing papers to packaging components and converted board articles.

Why this vocabulary matters

Vocabulary standards are reference tools for naming, not performance standards that prescribe tests or compliance thresholds. TS ISO 4046-4 is therefore useful for manufacturers, suppliers, purchasers, catalogue editors, translators, and technical writers who need a shared and precise language for paper and board products. The inclusion of English and French definitions also supports multilingual mapping of terms in international trade and documentation.

This standard is based on ISO 4046-4:2016 and belongs to the broader ISO 4046 vocabulary family covering paper, board, pulps, and related terms.
