EN ISO 527 Plastics - Determination of Tensile Properties

The EN ISO 527 standard, developed by the International Standards Organization (ISO), describes general principles and test methods for determining the tensile properties of plastics and plastic composites under defined conditions. Several different test methods are defined in the sections of this standard to suit different types of materials. These test methods are used to investigate the tensile behavior of test specimens and determine other aspects of the relationship of tensile strength, tensile modulus and tensile stress under defined conditions.

The EN ISO 527 standard is mainly suitable for materials such as:

• Rigid and semi-rigid molding, extrusion and casting thermoplastic materials and rigid and semi-rigid thermoplastic sheets and films, including filled and reinforced compounds, in addition to unfilled types
• Rigid and semi-rigid thermosetting molding materials, including filled and reinforced compounds, and rigid and semi-rigid thermosetting sheets, including laminates
• Fiber-reinforced thermosets and thermoplastic composites with unidirectional or non-unidirectional reinforcements, e.g. mat, woven fabrics, woven cords, chopped strands, combination and hybrid reinforcement, rovings and milled fibers and sheets made of pre-impregnated materials
• Thermotropic liquid crystal polymers

The test methods described in this standard are not suitable for use with solid cellular materials or sandwich structures containing cellular materials normally defined in the ISO 1926 standard.

The EN ISO 527 standard consists of the following sections under the heading "Plastics - Determination of tensile properties":

• EN ISO 527-1 Part 1: General principles
• EN ISO 527-2 Part 2: Test conditions for molding and extrusion plastics
• EN ISO 527-3 Part 3: Test conditions for films and sheets
• EN ISO 527-4 Part 4: Test conditions for isotropic and orthotropic fiber-reinforced plastic composites
• EN ISO 527-5 Part 5: Test conditions for unidirectional fiber-reinforced plastic composites

Among the numerous tests, measurements, analyses, and evaluations our organization provides for businesses in various sectors, we also offer testing services for determining the tensile properties of plastics within the scope of the EN ISO 527 standard , thanks to our trained and expert staff and advanced technological equipment.
