What is ISO 3385 – Testing cellular polymeric materials about?
ISO 3385 is an International Standard that focuses on flexible cellular polymeric materials. It gives a determination method for fatigue by constant-load pounding.
ISO 3385 specifies a method for the determination of loss in thickness and loss in hardness of flexible cellular materials intended for use in load-bearing applications such as upholstery.
ISO 3385 gives a method that is applicable to both, standard size test pieces cut from slapstick material and shaped components. The measured loss in thickness and loss in hardness is related to, but are not necessarily the same as, the losses likely to occur in service.
Note: ISO 3385 is not intended to function as a detailed engineering design specification for fatigue apparatus.
Who is ISO 3385 - Testing cellular polymeric materials for?
ISO 3385 on testing flexible cellular polymeric materials is useful for:
- Manufacturers of polymeric materials
- Entities dealing with polymeric materials
- Polymer research entities
- Testing laboratories
- Regulatory authorities
- Quality control teams
Why should you use ISO 3385 - Testing cellular polymeric materials?
The procurement of flexible cellular polymeric materials is a very complicated procedure, where the hardening of polymers, gas expansion, cell formation, etc., should be balanced. In addition, there is a wide variety of technologies available for the production of foams, which can often complement each other.
ISO 3385 lays down the technicalities to perform a procedure to determine the fatigue by the constant-load pounding of the flexible cellular polymeric materials. It gives you detailed information about the apparatus needed to perform the test, explains the principle of the test, and helps the users to execute the calculations as well as the content of the final test report.
ISO 3385 aims to provide recommendations and guidance for harmonized procedures for the determination of fatigue by constant-load pounding. It helps the users in the assessment of the service performance of flexible cellular polymeric materials based on rubber latex or polyurethane used in load-bearing upholstery.
