ADDING LOGOS
Adding company logos to workwear is a common request, and Tranemo delivers around 100,000 logo-bearing garments each year. Before adding logos to flame retardant clothing it is important to know that garment certifications impose requirements on various types of marking, and the wrong solution can reduce the protection provided by a garment. Heat seal badges, sew-on badges or embroidery that cover an area less than 10 cm² do not require flame retardant testing under the EN ISO 14116 standard.
HEAT SEAL BADGES
Heat seal badges need to be tested and approved before they are used on Flame Retardant garments. The heat seal badges that Tranemo produce are tested and approved for EN ISO 14116 and EN 1149-5 when attached to a Tranemo Flame Retardant garment. When a heat seal badge is exposed to high heat, it normally retains the energy for a longer period of time than the fabric. From a safety perspective, a large solid print is not recommended. The best placement is where there are several layers of fabric underneath that will help protect your skin. For heat seal badges, Tranemo uses InduTrans 15FR, an all-round heatseal badge that works on most materials. Covers dark garments to 99% and can be washed in 60 degrees and tumble dried in low temperatures (garment washed and dried inside out). InduTrans is tested and complies to the requirements for EN ISO 14116 and 1149-5 when applied to most Tranemo Flame Retardant fabrics.
SEW-ON BADGES
Sew-on badges for flame retardant garments must be made from a flame retardant fabric. The EN 1149-5 standard requires that sew-on badges are permanently attached.
EMBROIDERY
If a flame retardant garment is to be embroidered directly, flame retardant embroidery thread must be used.
LOGOS ON HIGH VISIBILITY GARMENTS
High visibility garments that are certified to EN ISO 20471 must always have a minimum area of fluorescent fabric, and garments are certified in different visibility classes depending on the size of this area. To avoid reducing the fluorescent surface area, logos should be placed on an area of contrasting colour or be kept relatively small. Tranemo recommends that logos are not placed on the fluorescent surface at all. The same recommendation also applies to upper garments that are certified to EN ISO 20471 and have a relatively small fluorescent area (e.g. short-sleeved garments, women’s garments or garments that have a large proportion of non-fluorescent fabric). If unsure, contact Tranemo for help in calculating the high visibility area of an individual garment and any restrictions that apply.
