Featured ISO Standards
Start with the ISO methods most often used for tensile and flexural work across plastics, rubber, films, and sheet materials.
ISO 527-2
A working guide to tensile testing of moulding and extrusion plastics, covering specimen types, modulus, yield, elongation, speed selection, and the setup logic needed for repeatable ISO execution.
ISO 178
Three-point bending guidance for span selection, flexural modulus, deflection limits, and test setup.
ISO 37
Rubber tensile testing with attention to dumbbell dies, gripping, extension measurement, and final reporting.
ISO 527-3
Film and sheet tensile testing for isotropic and anisotropic materials with a focus on thin-material handling.
ASTM Standards
Compare ISO guidance with ASTM routes used for US-facing compliance, validation, and QA workflows.
Quick Access
ISO Standards Directory
Jump directly into the ISO methods most frequently used across plastics, elastomers, films, and flexural workflows.
Tensile Properties of Moulding and Extrusion Plastics
Core tensile guidance for rigid plastics where specimen selection, modulus, yield, and elongation all shape the result.
Tensile Properties of Films and Sheets
A focused route for thin plastic materials where gauge definition, gripping, and directional behavior affect interpretation.
Flexural Properties of Plastics
Use when span, deflection, flexural modulus, and bending response define the method selection and fixture planning.
Tensile Testing of Vulcanized Rubber
Reference for rubber tensile work where die type, dumbbell geometry, and elongation measurement drive consistency.
Practical Notes
Quick Reference
Three reminders that usually tighten ISO execution before the first specimen even reaches the grips.
Control Preparation Before You Tune the Machine
Dimensions, machining route, edge finish, and conditioning frequently decide whether the result is meaningful before setup details do.
Choose the Grip or Fixture for the Material Behavior
The correct grip is the one that preserves the specimen and the failure mode, not the one that merely fits the frame.
Capture Enough Setup Detail to Reproduce the Result
Extension measurement, conditioning, speed, and template version should be documented tightly enough for another operator to rerun the test.
