Full title and description

St ISO 3914-3-1994 — Textile machinery and accessories — Cylindrical tubes — Part 3: Dimensions, tolerances and designation of tubes for tape yarns. This International Standard specifies the principal dimensions, permissible tolerances and a designation system for cylindrical tubes used to wind tape yarns; it also gives directives on tube characteristics and on methods to control inner diameter and length.

Abstract

ISO 3914-3:1994 (Edition 2) cancels and replaces ISO 3914-3:1984. The document defines recommended dimensions, dimensional tolerances and a designation scheme for cylindrical tubes intended for tape yarns used in textile machinery. It includes guidance on tube characteristics and inspection/control of inner diameter and length to ensure interchangeability and reliable performance in winding and handling operations.

Scope

This part of ISO 3914 specifies the main dimensions, tolerances and designation of cylindrical tubes specifically intended for tape yarns (flat ribbon-like yarns). It provides directives for tube characteristics (geometric features relevant to winding and handling) and for methods to check and control the inner diameter and the length of the tube so that tubes from different suppliers remain interchangeable on textile winding equipment.

Key topics and requirements

• Definition of nominal tube dimensions relevant to tape yarn winding (inner diameter and length ranges).
• Permissible tolerances for inner diameter and length to ensure fit and concentricity on spindles and winding devices.
• A standardized designation system for tubes to communicate size and basic characteristics unambiguously.
• Guidance on the geometric characteristics of tubes (e.g., straightness, ends, bore finish) relevant to performance.
• Recommendations for control and inspection methods for inner diameter and length to verify conformity.
• Compatibility considerations with other parts of the ISO 3914 series (ensuring consistent dimensional practice across different yarn types).

Typical use and users

Manufacturers of cylindrical tubes for the textile industry, producers of textile winding and yarn-handling machinery, quality assurance and metrology laboratories, procurement/specification engineers in textile mills, and standards/technical committees use this standard to ensure component interchangeability, reduce downtime from mismatched parts and support international trade in textile auxiliary components.

Related standards

Other parts of the ISO 3914 series addressing cylindrical tubes for different yarn types and recommended dimensions, for example ISO 3914-1 (Recommended main dimensions), ISO 3914-2 (Tubes for open-end spinning machines), ISO 3914-4 (Tubes for textured yarns) and ISO 3914-5 (Tubes for continuous spin-drawn synthetic filament yarns). The standard is developed under ISO/TC 72 (Textile machinery) and has national adoptions or identical national standards in several countries.

FAQ

Q: What is this standard?

A: ISO 3914-3:1994 is an International Standard that sets out dimensions, tolerances and a designation system for cylindrical tubes used specifically for tape yarns in textile machinery.

Q: What does it cover?

A: It covers the main dimensional parameters (inner diameter and length), permissible tolerances, a designation scheme and directives for tube characteristics and inspection methods to control bore and length.

Q: Who typically uses it?

A: Tube manufacturers, textile machinery builders, quality/control labs, procurement and maintenance teams in textile mills, and standards bodies use it to ensure parts are compatible and meet agreed dimensional requirements.

Q: Is it current or superseded?

A: ISO 3914-3:1994 (Edition 2) is the current published edition of this part. It replaced the 1984 edition and has been subject to ISO periodic review; it was confirmed in ISO’s systematic reviews (most recently confirmed on 19 August 2021). Users should check with their national standards body or ISO for any amendments or withdrawals after that confirmation date.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 3914 series on cylindrical tubes for textile machinery. Other parts address recommended main dimensions and tubes for different yarn types (for example ISO 3914-1, -2, -4, -5).
