ISO 527-3 Plastics - TENSILE PROPERTIES - PART 3: FOR FILMS AND SHEETS
ISO 527-3 specifies the test conditions for determining the tensile properties of plastic films and sheets with a thickness less than 1 mm, based on the general principles of ISO 527-1. Provides standardized procedures to measure critical mechanical parameters including tensile strength, yield strength, elongation at break, and Young's modulus for thin plastic materials. It is critically important because thin films behave very differently under stress compared to rigid plastics; they are more prone to tearing, slipping, and deformation. By standardizing the test conditions, this document ensures that material specifications, quality control, and research data are globally comparable and reliable. Specimen created following ISO 527-3 can be used to determine the tensile properties of thin plastic sheets and films including the tensile modulus of elasticity and the tensile energy to break (TEB).

Frequently Asked Questions
Single Column vs Double Column Universal Tensile Testers – How to Choose | UnitedTest
When selecting a universal tensile tester for material testing, manufacturers and laboratories often compare single column and double column (dual column) models. Both machines perform tension, compression, bending and shear testing, yet they differ significantly in load capacity, structural rigidity, installation requirements and suitable application scenarios. Understanding their differences helps you pick the most cost-effective testing solution.
Single Column Tensile Tester
Single column tensile testers adopt one vertical support frame to drive the moving crosshead. These are almost exclusively tabletop units with compact dimensions.
Key characteristics
Force range: Normally for low and medium loads, commonly from 5 N up to 5 kN.
Space requirement: Small footprint, fits standard laboratory benches, no dedicated ground foundation needed.
Structure rigidity: Moderate rigidity; not recommended for high load testing or rigid large-size specimens that may create lateral force.
Price and maintenance: Lower purchase cost and simpler routine maintenance.
Best-fit applications
Thin films, paper, fiber, yarn, rubber, elastomers, small plastic samples, adhesive specimens, tiny electronic components, medical biomaterials and small textile products. Widely used for factory incoming quality control, university teaching labs, and small third-party testing institutes.
Double Column Tensile Tester
Double column tensile testers feature two parallel vertical columns to support the crosshead. Available as tabletop or floor-standing configurations.
Key characteristics
Force range: Covers medium to high loads, typically starting at 10 kN and reaching 300 kN or higher.
Structure rigidity: Excellent structural stability. Resists deflection when lateral force occurs during bending, shear or compression tests.
Test space: Larger vertical and horizontal test stroke, able to accommodate bigger specimens and large fixtures.
Price and installation: Higher investment cost; heavy-duty floor-standing versions sometimes require flat reinforced ground installation.
Best-fit applications
Thick plastic sheets, metal strips, composite materials, structural adhesive joints, GRP pipes, large rubber parts, automotive components, construction materials, aerospace specimens and other high-strength materials. Suitable for formal product certification, advanced material research and heavy-load mechanical performance verification.
