STANDARDS OF HIGH TEMPERATURE FABRICS
UNE EN 1869 has been created and approved by CEN/TC 70 Technical Committee "Manual equipments to protection against fire" reaching the national standard rank. According to CEN/CENELEC Internal Rule, the following countries are forced to adopt this European Rule: Germany, Austria, Belgium, Denmark, Spain, Finland, France, Greece, Iceland, Italy, Luxemburg, Norway, Netherlands, Portugal, United Kingdom, Sweden and Switzerland.
This regulation especifies the minimun requirements and test methods to extintion clothing, including hoods, aprons, sleeves and spats used for users' protection during the welding operations and affine processes. This type of protection clothes are used to protect a user from small cast metal spashes, small contact periodes with fite, radiant heat produced by the welding arc and minize the chance of an electrical shoc by the accidental contact with electrical conductors with a 100 V d.c. voltage.
Electrodes must be displayed over the opposite surfaces of the testing material. Continual voltage tension must be applied to electrodes and electrical resistance of the testing material is determined.
