ISO 9959-2-1999 PDF

Full title and description

Numerically controlled draughting machines — Draughting test for evaluation of performance — Part 2: Monochrome raster plotters. This part of ISO 9959 specifies a standardized draughting (plotting) test and related definitions for evaluating the graphic output quality and performance of monochrome raster-based plotters used for technical drawing and CAD output.

Abstract

This standard defines test procedures, terminology and measured characteristics (for example: point size and overlap, image density, resolution and addressable resolution, linearity, positional accuracy, margins, image permanence and environmental test conditions) that allow objective assessment of monochrome raster plotter output for draughting applications. It is intended so that performance comparisons and acceptance testing can be made independently of machine type.

Scope

ISO 9959-2:1999 applies to monochrome raster plotters and specifies a draughting test to evaluate image quality and performance characteristics relevant to technical draughting. The procedures and definitions are written so that the output of different machines can be compared objectively, covering image formation speed, resolution (addressable resolution), point characteristics, density and contrast, positional accuracy and related image‑quality attributes used in technical drawing applications.

Key topics and requirements

• Definitions and terminology for raster plotter image characteristics: point size, point overlap, image density (reflection/transmission), grayscale, resolution and addressable resolution.
• Test methods to determine image formation speed, time to create a standardized draughting output, and preheat requirements.
• Measures of geometric quality: positional accuracy, linearity, ability to render 90° angles, variation of diameter and other line/shape fidelity metrics.
• Image area and margin measurements (useful plotting area), and methods to determine usable plotting width/length.
• Durability/permanence tests including resistance to light and to water for the specified test media.
• Reporting format and normative references (for example references to lettering standards used in technical drawing).

Typical use and users

Used by manufacturers of plotters and raster output devices to validate performance claims, by test laboratories and quality departments for acceptance testing, and by procurement/specification engineers who need objective performance data for selecting or qualifying monochrome raster plotters for technical drawing and CAD output. Technical committees and standards bodies consulting on drafting and plotting equipment historically used this document when comparing raster plotter capabilities.

Related standards

ISO 9959 is a multi‑part series: Part 1 covers vector plotters (ISO 9959-1) while Part 2 covers monochrome raster plotters. The document also references or aligns with technical drawing and lettering standards such as ISO 3098 (lettering) and related national equivalents (for example JIS B 3411-2:2002 which is identified as an identical / equivalent national adoption to ISO 9959-2:1999). National standards bodies’ catalogues and mirror documents provide localized metadata and withdrawal history.

FAQ

Q: What is this standard?

A: ISO 9959-2:1999 is the part of ISO 9959 that defines a draughting (plotting) test and related definitions for evaluating the output quality and performance of monochrome raster plotters used in technical drawing.

Q: What does it cover?

A: It covers test procedures, terminology and measurable characteristics such as resolution, point size and overlap, image density, grayscale performance, positional accuracy, linearity, margins, image permanence (light/water resistance) and image formation speed — all aimed at objective performance evaluation of monochrome raster plotters.

Q: Who typically uses it?

A: Manufacturers, test laboratories, QA/acceptance teams, procurement/specification engineers for CAD and technical drawing hardware, and standards/committee members concerned with draughting equipment performance.

Q: Is it current or superseded?

A: The ISO catalogue records ISO 9959-2:1999 as Withdrawn. National catalogues and standards vendors indicate the standard was later withdrawn from active status (national withdrawal records commonly reference May 2005 or subsequent national withdrawal dates). Users seeking normative, current test methods should consult the ISO catalogue and their national standards body for any replacements or more recent, related documents.

Q: Is it part of a series?

A: Yes — ISO 9959 is a series for draughting tests and evaluation of numerically controlled drawing machines; Part 1 addresses vector plotters and Part 2 addresses monochrome raster plotters.

Q: What are the key keywords?

A: numerically controlled draughting machines; monochrome raster plotters; plotter performance; draughting test; resolution; image density; technical drawing equipment; ISO 9959.
