ISO 604 Compressive Strength Testing of Plastics

Share:

ISO 604:2002 outlines the method for determining the compressive properties of plastics, including strength and modulus measurements. By standardizing how these tests are conducted, we can guarantee that our results are both accurate and globally recognized.

ISO 604 Compressive Strength Testing of Plastics

Key Specifications of Test Specimens:

Cylindrical Specimens:

Diameter: Commonly set at 10 mm or 14 mm.

Height: Adjusted to twice the diameter, securing a 2:1 ratio that minimizes errors like buckling during testing.

Prismatic Specimens:

Dimensions: Typically 10 mm in width and thickness.

Height: Twice the smallest lateral dimension to uphold structural integrity under compression.


Compliance with ISO 604:2002 allows us to deliver reliable data that supports critical decisions in product development and quality control. It ensures that materials meet expected standards for durability and safety across various applications—from automotive components to consumer electronics.


Industries Benefiting from ISO Compliant Testing:

Automotive: Ensuring components can withstand stresses under load.

Aerospace: Certifying materials for safety and performance in extreme conditions.

Consumer Goods: Guaranteeing that everyday products are durable and safe.
