The “ISO 6603 Plastics - Determination of puncture impact behavior of rigid plastics” standard, published by the International Organization for Standardization (ISO), consists of the following sub-sections published under the same title:
These falling arrow methods are used to study the behavior of plastic sheets or molds under an impact applied perpendicular to the plane of the sample. This standard can be used if it is sufficient to characterize the impact behavior of plastics with an impact-rupture energy threshold value based on a large number of test specimens. If a force-deflection or force-time diagram recorded at a nominally constant impact velocity is required for detailed characterization of impact behavior, the ISO 6603-2 standard applies.
These test methods are applicable to samples with a thickness between 1 mm and 4 mm. For thicknesses less than 1 mm, the ISO 7765 standard should preferably be used. Thicknesses greater than 4 mm can be tested if the equipment is suitable, but this test is outside the scope of ISO 6603-1 and ISO 6603-2 standards.
These methods are suitable for the following types of materials:
These methods also apply to finished products, laminates, and molded or machined samples from extruded or cast sheets.
Test results are comparable only if the sample preparation conditions, dimensions, and surfaces, as well as the test conditions, are the same. In particular, results obtained from samples of different thicknesses cannot be compared. A comprehensive assessment of the response to impact stress requires determinations as a function of impact velocity and temperature for different material variables such as crystallinity and moisture content.
The impact behavior of finished products cannot be directly predicted from this test, but samples of finished products can be taken for testing using these methods.
In principle, the impact resistance of test specimens of suitable size is determined by striking the specimen with a lubricated weighted impact tip dropped vertically from a known height. The test specimen is struck at its center with an impact tip perpendicular to its surface. Two methods are allowed to adjust the energy at the moment of impact: changing the mass at a constant height and changing the height at a constant mass.
The variable height procedure is speed-dependent, and different results can be observed depending on the strain rate of the material. Two statistical test methods are given:
The test method is valid for samples with a thickness between 1 mm and 4 mm. This method is suitable for use with the following types of materials:
This method also applies to molded or processed samples from finished products, laminates, and extruded or cast sheets.
Test results are comparable only if the sample preparation conditions, dimensions, surfaces, and test conditions are the same. In particular, results obtained from samples of different thicknesses cannot be compared. A comprehensive assessment of the response to impact stress can be obtained by determining the impact velocity and temperature as a function of different material variables such as crystallinity and moisture content.
The impact behavior of finished products cannot be directly predicted from this test, but samples of finished products can be taken for testing using this method. The test data developed using this method is not intended for use in design calculations. However, information about the typical behavior of the material can be obtained by testing samples prepared at different temperatures and impact velocities, with varying thicknesses and under different conditions.
The purpose of this standard is not to provide an interpretation of the mechanism occurring at each point on the force-deflection diagram. Such interpretations are the task of scientific research.
In principle, the test specimen is pierced through its center using a lubricated impact drill bit, perpendicular to the test specimen surface and at a nominally uniform speed. The resulting force-deflection or force-time diagram is recorded electronically. The test specimen should (preferably) be held in a fixed position during the test.
The force-deflection diagram obtained from these tests records the impact behavior of the sample, allowing for the inference of various characteristics of the material's behavior.
ISO 6603 standards are globally recognized standards that measure how well rigid plastics resist high-speed puncture and tearing. This is a type of impact damage that traditional tests like Charpy or Izod cannot properly assess. These standards are considered important for the following reasons:
In conclusion, the ISO 6603 standard is one of the most important standards characterizing the high-speed puncture impact performance of rigid plastics. By bridging simple drop weight tests with highly sophisticated instrumented testing, it provides engineers with reliable and comparable data on how plastics resist penetration and absorb energy under conditions that simulate real-world accidents or misuse.
For many years, our organization, with its competent and experienced staff, has been understanding the needs of its clients, providing the advanced testing services they require, and assisting in the establishment, implementation, and improvement of management systems. Within this framework, we also provide testing services to businesses in accordance with the "ISO 6603 Plastics - Determination of puncture impact behavior of rigid plastics" standard.
