The first edition of the IEC standard (04/1994) focused on contact protection. Little attention was paid to fire safety. Therefore, unsupervised appliances such as coffee machines, dryers or high-speed heaters repeatedly caused fires. With the fourth edition of the household appliance standard IEC/EN 60335-1, the fire safety of these appliances was improved in May 2001 in that all components had to pass a glow-wire test. Now the requirements defined for the household appliance standard are also being applied to the fuseholder standard.
This has consequences for the manufacturers of fuseholders and appliance inlets with integrated fuseholders. They must test the glow-wire resistance of the used materials and replace the materials used with new glow-wire resistant material if need be. About 80 of the SCHURTER product types are affected by the updated standard. The company is in the process of converting the broad assortment of fuseholders and appliance inlets to fuseholders that meet the new requirements.
