ISO 527-1 Plastics Tensile Properties Testing (General Principles)

← Back to all standards

ISO 527-1 defines the general principles for determining the tensile properties of plastics and plastic composites. To match this to your program, talk with our team.

What ISO 527-1 Covers

It sets the common method, specimen requirements, and reported properties for plastics tensile testing, with material-specific conditions given in the later parts.

How the Test Is Run

A plastic specimen is pulled in tension at a controlled speed while force and extension are recorded, and tensile strength, modulus, and elongation are determined from the stress-strain curve.

Why It Matters

ISO 527-1 is the backbone of plastics tensile testing; accurate strain measurement and correct specimen preparation keep results comparable.
