Full title and description
ISO 9957-2:2019 — Fluid draughting media — Part 2: Water-based non-India ink — Requirements and test conditions. Specifies performance requirements and standardized test conditions for water-based (non‑India) draughting inks intended for use in technical/draughting pens on natural tracing paper to produce stable black line technical drawings.
Abstract
This International Standard specifies the requirements and test conditions for water‑based non‑India inks intended for use in draughting instruments and on natural tracing paper (conforming to ISO 9961), with the objective of providing consistent, durable black line technical drawings. It defines key performance characteristics (line quality, optical density, drying and set times, adhesion, erasability, and resistance to water and fading) and the methods for measuring them under specified laboratory conditions.

Scope
ISO 9957-2:2019 applies to water‑based draughting inks other than India (lamp) inks that are intended for use in draughting instruments (for example tubular technical pens) on natural tracing paper that meets ISO 9961. The standard establishes required properties and specifies standardized test conditions and methods to assess whether an ink meets those requirements for producing black line technical drawings suitable for drafting and archival handling.
Key topics and requirements
- Definitions and classification of water‑based non‑India draughting inks.
- Specified test conditions (standard atmosphere, substrate—natural tracing paper conforming to ISO 9961, instruments, and test pens).
- Line width and dimensional consistency when used with defined pen tips.
- Optical density (blackness) requirements for legible, high‑contrast lines.
- Drying time and set/draw stability under standard laboratory conditions.
- Adhesion to natural tracing paper and resistance to smudging/erasability.
- Resistance to water and requirements for minimal bleed or loss of definition on exposure.
- Fade resistance / lightfastness expectations appropriate for technical drawings.
- Conformance test methods and pass/fail criteria for the above characteristics.
Typical use and users
This standard is used by ink manufacturers, pen and instrument producers, materials testing laboratories, quality managers in technical documentation and drafting departments, archives and conservation specialists assessing stability of drawn originals, and standards committees. Typical applications include specification, testing and acceptance of draughting inks for engineering and architectural drawing, reprographic workflows, and archival recordkeeping where line fidelity and longevity are required.
Related standards
Related standards in the draughting and drawing equipment area include ISO 9957‑1 (water‑based India ink — requirements and test conditions), ISO 9957‑3 (water‑based coloured draughting inks), ISO 9961 (natural tracing paper — requirements), and standards for technical pens and pen tips (for example parts of ISO 9175 and other ISO/TC 10 deliverables). These documents are commonly referenced together when specifying complete draughting media and test protocols.

FAQ
Q: What is this standard?
A: ISO 9957-2:2019 is an International Standard that defines requirements and standardized test conditions for water‑based non‑India draughting inks used to produce black line technical drawings on natural tracing paper.
Q: What does it cover?
A: It covers performance characteristics (line width, optical density, drying time, adhesion, erasability, resistance to water and fading) and the test methods and conditions to assess those characteristics when inks are used in draughting instruments on natural tracing paper conforming to ISO 9961.
Q: Who typically uses it?
A: Ink manufacturers, technical pen makers, test laboratories, drafting and reprographics departments, archivists, and standards bodies use it to specify, test and verify draughting ink performance.
Q: Is it current or superseded?
A: ISO 9957-2:2019 is the current (second) edition published in 2019 and supersedes the 1995 edition of the same part.
Q: Is it part of a series?
A: Yes — it is Part 2 of the ISO 9957 series (Fluid draughting media). Other parts address India inks (Part 1) and coloured draughting inks (Part 3), and the series is used alongside related standards such as ISO 9961 for tracing paper and ISO documents on technical pens.
