Full title and description

ISO 2690:1973 — Unrecorded magnetic tapes for instrumentation applications — Physical properties and test methods. (Russian title: «Банды магнетические вireгие для записи измерений — Физические свойства и методы испытаний».)

Abstract

This short ISO standard (2 pages) specifies the physical characteristics and the test methods to be used when qualifying unrecorded magnetic tape intended for instrumentation and measurement applications, including dimensional and surface properties and simple mechanical tests to ensure interchangeability and reliable performance.

Key bibliographic details and lifecycle (withdrawn) as recorded in ISO and major standards catalogues.

Scope

Specifies the physical properties to which unrecorded magnetic tape for instrumentation should conform and gives simple test methods for assessing those properties (for example dimensional tolerances, longitudinal curvature/radius, surface and coating-related characteristics and basic mechanical checks used to confirm acceptability for measurement-recording applications). The standard was intended to complement other dimensional and interchange standards for instrumentation tape.

Key topics and requirements

• Definition of the tape type and intended instrumentation use (unrecorded magnetic tape for measurement/interchange).
• Specified physical parameters: nominal thickness, coating/face properties, edge condition and minimum radius/longitudinal curvature requirements for safe handling and reliable transport.
• Simple mechanical tests: checks for curvature, tensile handling, and dimensional stability over a test length (examples include a 1 m test for longitudinal curvature described in the text).
• Surface and coating inspection criteria and test procedures to detect unacceptable defects that would affect recording or playback in instrumentation systems.
• Reference to related dimensional and interchange standards for reels, hubs and tape geometry (for full interchangeability requirements).

Typical use and users

Intended for manufacturers of magnetic instrumentation tape, quality and testing laboratories, instrument manufacturers and procurement/specification engineers who need a concise set of physical acceptance tests for unrecorded tape used in measurement and data-logging systems. The standard served as a short, practical specification supporting interchangeability between suppliers and instrumentation equipment.

Related standards

ISO 1859 (general dimensional requirements for unrecorded magnetic tapes for interchange instrumentation applications) is explicitly referenced; other related ISO/R legacy documents and ISO standards on reels/hubs and tape handling are also relevant for full interchangeability and mechanical interfaces.

FAQ

Q: What is this standard?

A: ISO 2690:1973 is an ISO International Standard that defined the physical properties and basic test methods for unrecorded magnetic tape intended for instrumentation (measurement) applications.

Q: What does it cover?

A: It covers a compact set of physical requirements and simple test procedures (dimensional checks, curvature/radius limits, surface/coating checks and basic mechanical tests) to confirm that unrecorded tape is suitable for use in instrumentation recording and interchange.

Q: Who typically uses it?

A: Tape manufacturers, test laboratories, instrumentation equipment manufacturers and procurement/specification engineers concerned with tape quality and interchangeability.

Q: Is it current or superseded?

A: ISO 2690:1973 has been withdrawn and is no longer a current ISO active standard; catalog records show it as withdrawn (ISO catalog and standards stores indicate withdrawal and list the publication/withdrawal lifecycle). For current dimensional/interchange requirements users should consult related, active ISO standards (for example ISO 1859 and later tape-handling/format standards).

Q: Is it part of a series?

A: It was produced alongside other short ISO documents addressing magnetic tapes for instrumentation (e.g., ISO 1858/1859 and related ISO/R legacy items). These documents together addressed tape dimensions, reels/hubs, winding and physical acceptance criteria for instrument interchange.

Q: What are the key keywords?

A: Magnetic tape, instrumentation, unrecorded tape, physical properties, test methods, dimensional requirements, interchangeability, ISO 2690.
