Full title and description

St ISO 3272-2-1978 rus — Microfilming of technical drawings and other drawing office documents — Part 2: Quality criteria and control. This entry refers to the ISO international standard ISO 3272-2:1978 (first edition, May 1978) and the Russian-language publication/recording of that part devoted to quality criteria and control for microfilming of drawing-office documents.

Abstract

Specifies quality criteria, inspection procedures and control measures for microfilming technical drawings and related drawing-office documents. The document defines acceptable physical and optical properties (legibility, densities, curl, resolution and defects) and gives methods to check reproducibility and acceptability of microfilm copies. The 1978 edition was later amended and ultimately superseded by a revised part in 1994.

General information

• Status: Withdrawn / superseded (withdrawal and replacement recorded).
• Publication date: 1978-05 (first edition, May 1978).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 37.080 (Document imaging applications); 01.100.01 (Technical drawings in general).
• Edition / version: Edition 1 (1978).
• Number of pages: 4 pages (1978 edition).

Scope

Applies to microfilming operations for technical drawings and other drawing-office documents produced in drawing offices, giving quality criteria and control procedures to ensure reproducible, legible microfilm images suitable for archival and exchange purposes. The original 1978 text covers general quality checks; later revisions (1994) narrowed focus to specific film types (for example, 35 mm silver-gelatin).

Key topics and requirements

• Definition of quality criteria for microfilm images: legibility, resolution, contrast and optical density.
• Inspection and control procedures to verify reproducibility and acceptability of microfilm copies.
• Limits on physical film properties (curl, defects, splices) and acceptable tolerances for processed film.
• Requirements for test targets, measurement methods and sampling for quality checks.
• Guidance on record-keeping and acceptance criteria for archival or exchange-ready microforms.

Typical use and users

Intended for reprographic and micrographics units in engineering and architectural offices, archives, libraries and organizations that convert, preserve or exchange technical drawings on microfilm. Typical users include drawing-office managers, records managers, document-imaging technicians and quality/control personnel responsible for microfilm production and archival storage.

Related standards

Other related documents include ISO guidance on microfilm processing and ISO/TC 171 technical reports.

FAQ

Q: What is this standard?

A: ISO 3272-2:1978 (recorded here as St ISO 3272-2-1978 rus) is the international standard that defined quality criteria and control procedures for microfilming technical drawings and related documents (first edition, published May 1978).

Q: What does it cover?

A: It covers measurable quality parameters (legibility, resolution, optical density, film curl and defects), methods for inspection and sampling, and acceptance criteria for microfilm copies used for archival or exchange of drawing-office documents.

Q: Who typically uses it?

A: Reprographic and micrographics technicians, records and archives staff, engineering drawing offices, and quality/control personnel involved in producing and preserving microfilm copies of technical documents.

Q: Is it current or superseded?

A: The 1978 edition was amended in 1980 and subsequently withdrawn and superseded by ISO 3272-2:1994 (the 1994 revision addresses quality criteria specifically for 35 mm silver-gelatin microfilms). The 1978 text is therefore not the current active edition.

Q: Is it part of a series?

A: Yes — ISO 3272 is a multi-part series dealing with microfilming of technical drawings and drawing-office documents (for example, Part 1 covers operating procedures; Part 2 covers quality criteria and control). Later parts and revisions are published under the ISO 3272 series.

Q: What are the key keywords?

A: Microfilming, microfilm quality, technical drawings, legibility, optical density, curl, micrographics, ISO 3272-2.
