ISO 4046-2:2016

Overview

ISO 4046-2:2016 - "Paper, board, pulps and related terms - Vocabulary - Part 2: Pulping terminology" is an international vocabulary standard from ISO/TC 6. It defines pulping-related terms in English and French, providing standardized definitions for the pulp and paper sector. This second edition reinstates the earlier ISO 4046-2:2002 content and is part of the ISO 4046 series that documents terminology for paper, board, pulps and related products.

Key topics

The standard focuses on clear, bilingual pulping terminology rather than test methods or performance requirements. Notable elements included are:

• Definitions of common pulping types and products: chemical pulp, chemi-thermomechanical pulp (CTMP), chemi-mechanical pulp (CMP), mechanical pulp, bagasse pulp, bamboo pulp, brown mechanical pulp, and BCTMP.
• Process and material terms: black liquor, bleaching, bleached pulp, chemical recovery, chip refining, air-dry pulp and air-dry mass.
• Entry structure and indexing: terms are listed alphabetically (English), each entry may include preferred and admitted terms, subject field, cross-references (cf.), notes, and a numbering scheme (2.X) for series indexing.
• Bilingual conventions: English and French equivalents are provided; where no equivalent exists a five-dot symbol (. . . . .) indicates absence.
• References to other ISO documents used in definitions (for example ISO 801-1 and the layout basis ISO 10241).

Practical applications

ISO 4046-2:2016 is a vocabulary tool used to ensure consistent language across the pulp and paper value chain. Users include:

• Pulp and paper manufacturers and process engineers - to align internal and supplier terminology for pulping processes and products.
• Standards writers and technical committees - to harmonize definitions across related standards and specifications.
• Procurement and legal teams - to reduce ambiguity in contracts, product specifications and purchase orders.
• Laboratories, R&D and quality control - to standardize reporting and documentation.
• Translators, trainers and educators - to produce bilingual technical materials and training curricula with authoritative terminology.
• Regulatory bodies and auditors - to interpret and reference consistent terms in regulations and compliance documents.

Related standards

• ISO 4046 series: Part 1 (Alphabetical index), Part 3 (Paper-making terminology), Part 4 (Paper and board grades), Part 5 (Properties of pulp, paper and board).
• ISO 10241 (layout for standards) and ISO 801-1 (referenced for specific definitions).

ISO 4046-2:2016 is a reference vocabulary - essential for clear communication, specification writing and international collaboration in pulping, paper and board industries.
