Full title and description

ISO 10619-3:2011 — Rubber and plastics hoses and tubing — Measurement of flexibility and stiffness — Part 3: Bending tests at high and low temperatures. This part of ISO 10619 specifies a laboratory method for determining bending characteristics (including the force required for bending) of small-diameter rubber and plastic hoses and tubing over a wide temperature range. The standard is available as a PDF from national bodies and ISO.

Abstract

ISO 10619-3:2011 defines a bending-test procedure to measure flexibility and stiffness of rubber and plastics hoses and tubing at temperatures from −60 °C to +200 °C. The method measures bending forces and related behaviour when specimens are bent to a specified radius under controlled temperature conditions. The apparatus and test arrangement are intended primarily for hoses and tubing of small internal diameter (up to 12.5 mm).

Scope

This part of ISO 10619 specifies a method for the determination of the bending characteristics of rubber and plastics hoses and tubing over a temperature range from −60 °C to +200 °C. It covers measurement of the force required to achieve a specified bend and related observations. Because of the physical arrangement of the required test apparatus, the method is applicable primarily to hoses and tubing with small internal diameters (typically up to 12.5 mm). Normative references include general specimen preparation and dimensional measurement standards for hoses.

Key topics and requirements

• Test purpose: determination of bending flexibility and stiffness and the force required for bending.
• Temperature range: specified tests at sub-ambient and elevated temperatures from −60 °C to +200 °C.
• Applicability limit: apparatus suited to small-bore hoses and tubing (internal diameter up to about 12.5 mm).
• Test apparatus: details of bending fixtures, mandrels or loading arrangements and temperature conditioning equipment.
• Specimen preparation and conditioning: reference to ISO procedures for preparing and conditioning test pieces.
• Test procedure: specimen mounting, bend radius specification, loading rate and measurement of bending force.
• Reporting: required test conditions, specimen details, measured bending forces and any deviations from the method.

Typical use and users

Used by hose and tubing manufacturers, materials and product test laboratories, quality control departments, research and development teams, and standards committees. Typical applications include product characterization, comparative testing of formulations or constructions, contractual verification, and development of product specifications where temperature-dependent flexibility or bend-resistance is relevant (for example automotive, industrial, hydraulic and pneumatic hose applications).

Related standards

ISO 10619 is a multi-part series on measurement of flexibility and stiffness of hoses and tubing. Related parts include ISO 10619-1 (bending tests at ambient temperature) and ISO 10619-2 (bending tests at sub-ambient temperatures). The series also cross-references general standards for specimen preparation and dimensional measurement for rubber and plastics hoses and tubing.

FAQ

Q: What is this standard?

A: ISO 10619-3:2011 is an international test standard that specifies a bending-test method to determine the flexibility and stiffness of rubber and plastics hoses and tubing at high and low temperatures.

Q: What does it cover?

A: It covers apparatus, specimen preparation, conditioning, test execution and reporting for bending tests performed between −60 °C and +200 °C, and is intended mainly for small-bore hoses and tubing (internal diameter up to about 12.5 mm).

Q: Who typically uses it?

A: Hose and tubing manufacturers, independent and in-house test laboratories, quality and R&D teams, and standards bodies use this standard for product testing, comparison and specification.

Q: Is it current or superseded?

A: The 2011 edition is the published ISO edition for part 3; it has been subject to periodic review. Users should verify the current status through their national standards body or ISO before relying on the text for conformity purposes.

Q: Is it part of a series?

A: Yes — ISO 10619 is a multipart series. Part 1 covers ambient-temperature bending tests, part 2 covers sub-ambient-temperature tests, and part 3 covers high- and low-temperature bending tests (this document).
