Overview
ISO 3545-1:1989 is an international standard established by the International Organization for Standardization (ISO) that specifies symbols for use in the standards and technical specifications of steel tubes and tubular accessories with circular cross-sections. This standard standardizes terminology and symbols to facilitate clear communication and accurate documentation in the steel tubes industry. It replaces the 1981 version (ISO 3545:1981) and focuses on the most common symbols used in specifications-covering tests, tolerances, service conditions, and geometric characteristics relevant to steel tubes.
Key Topics
Symbol Definitions
ISO 3545-1 defines symbols for key parameters in steel tube manufacturing and specification, including:- D: Specified outside diameter
- T: Specified thickness
- L: Length of the test piece
- IM: Mass per unit length
- DN: Nominal size
- PN / PS: Nominal and service pressure
- TS: Service temperature
Testing Symbols
The standard includes symbols related to essential quality and performance tests for steel tubes:- Pressure test (PE): Symbolizes the test pressure causing stress in the metal
- Flattening test
- Drift expanding test
- Flanging test
Tolerance and Service Condition Symbols
Symbols relating to tolerances and conditions during service ensure uniform interpretations:- Ovality (degree of cross-sectional roundness deviation)
- Eccentricity (thickness variation within a cross-section)
- Radius of gyration
- Diameter-thickness ratio (important for structural calculations)
Illustrative Figures
Six figures accompany the document, illustrating symbol meanings and test setups to support standardized understanding.
Applications
ISO 3545-1 is essential for industries involved in the design, manufacture, testing, and use of steel tubes with circular cross-sections. Typical applications include:
- Engineering and Construction: Ensures consistent specification language for structural steel tubes commonly used in pipelines, mechanical supports, and frameworks.
- Manufacturing Quality Control: Standardized symbols help manufacturers accurately report test results and material characteristics.
- Technical Documentation: Facilitates uniform terminology in product datasheets, standards, and international trade documentation.
- Research and Development: Supports engineers and scientists in reporting precise test and product parameters when developing new tubular products.
The standard's adoption improves efficiency in procurement, quality assessment, and compliance monitoring across global steel industries.
Related Standards
ISO 3545-1 forms part of a broader series on steel tube symbolism and accessories:
- ISO 3545-2: Symbols for square and rectangular hollow sections
- ISO 3545-3: Symbols for tubular fittings with circular cross-section
- ISO 5252: Steel tubes - Tolerance systems, referenced for dimensional tolerances related to tubes
Together, these standards provide a comprehensive framework for standardizing terminology and specifications of steel tubular products, ensuring interoperability and clarity in international industrial and engineering practices.
Keywords: ISO 3545-1, steel tubes, tubular accessories, circular cross-section, symbols, specifications, pressure test, flattening test, flanging test, ovality, eccentricity, steel pipe standards, ISO steel pipe symbols, steel tube terminology, engineering standards.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale
d’organismes nationaux de normalisation (comités membres de I’ISO). L’élaboration
des Normes internationales est en général confiée aux comités techniques de I’ISO.
Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec I’ISO participent également aux travaux. L’ISO col-
labore étroitement avec la Commission électrotechnique internationale (CE11 en ce qui
concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques sont soumis
aux comités membres pour approbation, avant leur acceptation comme Normes inter-
nationales par le Conseil de I’ISO. Les Normes internationales sont approuvées confor-
mément aux procédures de I’ISO qui requièrent l’approbation de 75 % au moins des
comités membres votants.
La Norme internationale ISO 3545-l a été élaborée par le comité technique ISO/TC 5,
Tuyauteries en métaux ferreux et raccords métalliques.
Cette première édition de I’ISO 3545-l annule et remplace I’ISO 3545 : 1981 dont elle
constitue une révision mineure.
