How to source EN 16350 electrostatic dissipative gloves for ATEX-related workplaces, including yarn choices, coatings, test limits, MOQ and factory limits.
Start With the Ignition Risk, Not the Word ESD
For a paint mixing room, grain silo, solvent decanting bench or resin powder plant, the glove question is not simply whether the glove is anti-static. The buyer needs to know whether the glove can dissipate charge from the hand in a controlled way while still giving the grip, cut level and chemical splash protection needed for the task. The European glove standard to put on the brief is EN 16350:2014, which measures vertical electrical resistance of protective gloves. The usual pass requirement is below 1.0 x 10^8 ohms under controlled conditioning at 23 C and 25 percent relative humidity. This is different from ordinary electronics ESD packaging language. IEC 61340 is common around PCB benches, but ATEX-related workplaces are concerned with avoiding incendive discharge in explosive atmospheres. A glove can be marketed as ESD for electronics and still be unsuitable for a Zone 1 solvent area if the construction, coating thickness or humidity dependence is wrong. Also be clear that gloves do not carry ATEX equipment certification in the same way as powered devices under Directive 2014/34/EU. For PPE, the realistic route is EN ISO 21420 general requirements, EN 388 mechanical risks and EN 16350 electrostatic properties, with EN ISO 374 added only where chemical protection is genuinely needed.
Build Conductivity Into the Liner Before You Choose the Coating
The stable factory construction is a knitted liner with conductive fibre distributed through the yarn, not a normal polyester glove sprayed with a magic anti-static finish. Common options are 13 gauge nylon-carbon, 15 gauge nylon-carbon for finer assembly, or polyester with carbon filament stripes at regular intervals. Some buyers ask for stainless steel yarn, but it feels harsher, can affect dexterity and is usually better reserved for cut-resistant blends where EN 388 cut performance is also required. For a thin handling glove, a 15 gauge nylon-carbon liner with PU palm coating is a practical starting point. Coating choice can make or break the resistance result. PU is thin and leaves good fingertip control, so it is common for dry assembly, powder filling, weighing stations and carton handling around hazardous goods. Nitrile foam gives better oily grip but adds insulation if applied too thick. Sandy nitrile helps drums and valves, but the buyer should expect a heavier glove and slightly less touch sensitivity. Latex is rarely our first suggestion for solvent or oil environments, and natural rubber allergy questions can complicate distribution. If the job includes real chemical splash, do not pretend a palm-dipped knit glove is a chemical glove. Move the discussion to full nitrile, neoprene or supported chemical styles tested to EN ISO 374.
Do Not Mix Up EN 16350, EN 388 and Electrical Insulation
A proper product file should state the standards separately. EN ISO 21420 covers sizing, innocuousness, dexterity and marking principles. EN 388:2016 plus A1:2018 gives abrasion, blade cut, tear, puncture and optional ISO 13997 cut letter. EN 16350 covers electrostatic properties. None of these make the glove safe for live electrical work. If the buyer is asking for protection against electric shock, the relevant insulating glove standard is EN 60903, and that is a specialist dipped rubber product outside a normal Yiwu knit and dip work glove line. For many ATEX-adjacent handling jobs, EN 388 3121X or 4131X is enough, but metal drum handling, sharp sheet packaging or waste powder bags may need an ISO cut letter such as B or C. Once cut yarns are added, check the EN 16350 result again. HPPE, glass fibre and steel blends change resistance behaviour, and a thick nitrile coating can raise the final reading. We normally ask the buyer to approve one locked construction first: gauge, liner yarn, coating type, coating coverage, cuff colour and size range. Testing a loose concept is how projects waste 3 to 4 weeks before the first real pre-production sample.
Specify the Use Case by Zone Tasks and Contaminants
A glove for a solvent filling bench is not the same as a glove for a grain elevator bearing inspection. Solvent rooms may need low-lint nylon-carbon, good wet grip and compatibility with local chemical handling rules. Grain and sugar dust plants often need abrasion resistance, secure grip on sacks and no loose fibre shedding into product areas. Powder coating lines may need heat tolerance for short contact with warm hooks, but a normal PU carbon glove should not be sold as a contact heat glove unless it has EN 407 data. Give the factory a task list with surface, contaminant and replacement cycle. Examples are steel drums with oily residue, 25 kg paper sacks, aluminium scoops, glass bottles, plastic IBC caps or painted hooks at 60 to 80 C. For dry carton and sack handling, a 13 gauge nylon-carbon liner with micro-foam nitrile palm is usually more robust than PU. For small valve work or laboratory weighing near flammable powders, a 15 gauge PU palm glove gives better tactility. If the wearer needs forearm coverage, we can extend knitted cuffs or add a separate sleeve, but a seamless fully coated long chemical glove is a different production route and needs separate tooling.
Sampling, Testing and MOQ Need to Be Planned Together
For an OEM order, the first sample set normally takes 7 to 12 days if the carbon yarn, coating compound and former size are already available. If the buyer requests a new colour, uncommon cuff stripe system or a blended cut-resistant conductive yarn, allow 2 to 3 weeks before testing samples. EN 16350 testing should be run on the final construction, not only on the liner. A changed coating thickness, palm texture or washing process can move the electrical resistance result. Realistic MOQ for a private-label 13 gauge or 15 gauge carbon yarn dipped glove is usually 3,000 to 5,000 pairs per colour and construction, with size runs from 7 to 11. If the glove needs custom back-of-hand printing, individual polybags, barcode stickers and a retail header card, the packaging MOQ may become the higher limit, often 5,000 to 10,000 sets depending on print method. Bulk carton packing is simpler: 12 pairs per inner polybag and 120 pairs per export carton is common for lightweight dipped gloves, while sandy nitrile or cut-resistant versions may pack at 72 pairs per carton because of volume.
What GloveMark Can and Cannot Honestly Supply
GloveMark can develop knitted carbon yarn work gloves with PU, nitrile foam or sandy nitrile palm coatings, including OEM cuff colours, heat transfer logos, carton labels and importer barcodes. We can also coordinate third-party laboratory testing for EN 388, EN ISO 21420 and EN 16350 when the buyer needs a formal technical file for the EU or UK market. Our normal production inspection uses size checks, coating coverage checks, visual defect sorting and carton quantity control; for safety glove orders we usually discuss AQL 2.5 for major defects and AQL 4.0 for minor defects unless the buyer has a stricter inspection manual. We do not certify a workplace as ATEX safe, we do not issue notified body certificates ourselves, and we do not make EN 60903 live electrical insulating gloves on the same dipped knit line. We also will not promise chemical resistance for a palm-coated handling glove just because the coating is nitrile. If the application includes immersion in acetone, MEK, toluene or strong cleaning solvent, send the exact chemical name, concentration, contact time and required standard before sampling. The honest sourcing route is to lock the risk, choose the yarn and coating, test the finished glove, then scale production after the buyer signs off the laboratory report and sealed pre-production sample.
