BS EN ISO 178 Flexural Properties Testing of Consumer Plastics
The BS EN ISO 178 flexural properties testing method is widely used to determine the mechanical behavior of polymer and plastic materials under static bending load. This test evaluates how a specimen bends, stretches, or deforms when subjected to an applied force. The results are crucial for ensuring that consumer plastics meet specific performance requirements set by international standards.
The testing process involves subjecting a rectangular-shaped specimen cut from the plastic material to a defined loading regime. During this procedure, the sample is clamped at both ends and loaded in the middle until it breaks or deforms beyond acceptable limits. The flexural modulus (E-value), flexural strength, and flexural strain are measured during this process.
This standardized test method ensures that the plastic materials used in consumer goods meet the required mechanical properties as defined by the relevant ISO standard. It is an essential tool for quality assurance departments, R&D teams, and compliance officers to ensure product safety and performance.
For instance, in the case of a plastic chair, the flexural strength test ensures that it can withstand the weight of a person without breaking. Similarly, for food containers, this test guarantees that they do not collapse under pressure or temperature variations during packaging and shipping.
The BS EN ISO 178 method is applicable to various types of thermoplastics and thermosetting plastics. The testing procedure must be conducted in accordance with the relevant section of the standard, which specifies specimen dimensions, loading rates, and temperature conditions.
For quality control purposes, Eurolab recommends that specimens should not have any visible defects or surface irregularities that might affect the test results. Additionally, the test environment should be controlled to maintain a constant temperature and humidity level throughout the testing process.
The BS EN ISO 178 flexural properties testing method is applicable in various sectors such as automotive, medical devices, consumer goods, packaging, and construction materials. It ensures that the plastic components used in these products meet stringent mechanical performance requirements set by industry standards.
| Test Parameter | Description |
|---|---|
