Anotation

IEC TS 60695-2-20:2024, which is a technical specification, describes a test method that applies to solid electrical insulating materials of which test specimens can be provided. The test measures the time required to ignite a test specimen when it is affected by heat from an electrically heated wire wound around the test specimen. The test method can be used to provide classifications which can be used for quality assurance, the preselection of materials of products as described in IEC 60695-1-30, or to verify the required minimum classification of materials used in end products. This fourth edition cancels and replaces the third edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Removed all text which was related to drip or dripping, since in this 4th edition only ignition is taken into consideration for determination of the classification level; Title changed: "Hot wire coil test method" is now "Hot wire ignition (HWI) test method".
