IEC 60695 Electrical Safety Testing for Glow Wire Test of Appliances
The IEC 60695 series of standards is a cornerstone in electrical safety testing, ensuring that products comply with essential safety requirements. The Glow Wire Test (GWT) is one of the most critical tests within this standard series, designed to evaluate the ignition resistance of plastic materials used in various electrical appliances and devices.
The Glow Wire Test involves subjecting the specimen material to a controlled source of heat, specifically an electrically heated tungsten wire. The test apparatus generates a constant current through the wire, which heats it up to a specified temperature. This temperature is typically set at 650°C, but other temperatures like 750°C can also be used depending on the standard being followed.
The specimen material is exposed to this heated wire for a predetermined period, usually between 15 and 30 seconds. During this time, any potential ignition sources within the material are activated. The objective of the test is to observe if there is any flaming combustion or self-sustaining burning that can pose a risk to end-users.
The Glow Wire Test is particularly important for appliances like hair dryers, vacuum cleaners, and other small household devices where the safety of the user is paramount. By ensuring that these materials do not ignite under certain conditions, manufacturers can prevent potential accidents and comply with international safety regulations.
For accurate and reliable testing, it is crucial to follow stringent procedures. Specimen preparation involves selecting representative samples of the material in question. These samples are then placed on a support holder within the Glow Wire Test apparatus. The test setup must be calibrated precisely to ensure consistent results across different tests.
The test conditions—such as wire temperature and exposure time—are critical factors that can affect the outcome of the test. Variations in these parameters could lead to false positives or negatives, thereby compromising safety assessments. Therefore, adherence to international standards like IEC 60695 ensures consistency and accuracy in testing.
In addition to the primary test procedure, there are supplementary tests that complement Glow Wire Testing. These include flammability tests that assess how quickly a material ignites once exposed to an external flame source. Such complementary tests provide a more comprehensive evaluation of a product's safety characteristics.
Compliance with IEC 60695 standards is not just about meeting regulatory requirements; it also ensures the quality and reliability of products. By adhering to these stringent testing protocols, manufacturers can build trust among consumers and meet global market demands. This commitment to safety enhances brand reputation and fosters customer confidence.

Applied Standards
The Glow Wire Test is primarily governed by the IEC 60695-11 standard, which specifies the general requirements and test methods. This standard ensures that all tests are conducted under controlled conditions to yield reliable results.
In addition to IEC 60695-11, other relevant standards include:
- IEC 60738-12: Glow-wire Flaming Test for Plastic Materials Used in Electrical Appliances
- EN 61034: Safety of Machinery—General Requirements for Protective Devices Against Inflammation Hazards
- ASTM E559: Standard Practice for Determining the Ignition Temperature of Plastics by Glow-Wire Flaming Test
- IEC 60784-2: Protection against electrical shock in household appliances and similar equipment—Particular requirements for protection against electric shock
The application of these standards ensures that manufacturers are aware of the latest safety guidelines and can implement them effectively. Compliance with these international standards not only enhances product quality but also facilitates market access by meeting regulatory requirements.
