Description
The Bizweld American overall by Portwest (BIZ4) is a flame-resistant overall that provides protection against heat, welding sparks, and electric arc discharges. The garment is made of 100% cotton with a weight of 330 g/m² and is intended for welders and other professionals working in environments with an increased risk of flame and heat sources. The overall complies with several international standards for protective clothing.
For what work is the Bizweld American overall BIZ4 suitable?
The BIZ4 is suitable for welding work and related activities where there is a risk of welding arcs, welding sparks, and intense heat.
Thanks to the certification according to EN ISO 11611 Class 1 (A1+A2), the overall meets the requirements for welding clothing for less intensive welding techniques. The EN ISO 11612 standard (A1+A2, B1, C1, E2, F1) confirms protection against multiple heat sources, including convective heat, radiant heat, and molten metal sparks. This makes the overall suitable for use in the metalworking industry, maintenance sectors, and installation companies where there is a risk of flame.
What does the ATPV value of the Bizweld American overall BIZ4 mean and when do you choose this model?
The ATPV value (Arc Thermal Performance Value) indicates how much arc energy the fabric can absorb before there is a 50% chance of a second-degree burn. For the BIZ4, this value is 11.2 cal/cm² according to ASTM F1959/F1959M-12 and 10.9 cal/cm² (ELIM 8.3 cal/cm²) according to EN 61482-1-1.
You choose this model when you work in environments with a moderate risk of electric arc discharges and at the same time need protection against welding sparks and heat. Compared to a standard work overall, the BIZ4 offers certified flame and arc protection in one garment, making it practical for daily use on the shop floor.
The overall can be washed at a maximum of 40°C and must not be tumble dried; line drying and ironing at a maximum of 150°C is recommended.
