Industrial Coveralls & Workwear

Applicable Standard: EN ISO 13688:2013 — Protective Clothing (General Requirements), typically combined with EN ISO 14116 (Limited Flame Spread) where a flame-resistance claim is made; recognized by KEBS.

Industrial coveralls sit in a slightly different compliance position from most other PPE, because EN ISO 13688 is explicitly a general-requirements standard — covering ergonomics, sizing, ageing, and innocuousness (no harmful substances in prolonged skin contact) — and is only meaningful when combined with the specific hazard standard the coverall is actually being marketed against, most commonly EN ISO 14116 for limited flame spread. Importers who buy “flame-resistant” or “FR” coveralls purely on marketing copy, without checking which specific flame standard and index class the fabric was actually tested to, are the ones most likely to discover the hard way that their coveralls only resist brief, occasional flame contact rather than sustained exposure. It’s also worth being explicit about what EN ISO 14116 does not cover: it addresses limited flame spread on lightly exposed, incidental-contact garments, and is a materially lower bar than the heat-and-flame standards (such as ISO 11612) used for workers with regular, sustained exposure to flame or radiant heat — a coverall correctly marketed under EN ISO 14116 is not automatically suitable for a welder or furnace operator simply because both contexts involve “fire.”

Why This Category Gets Flagged

Three issues dominate. First, flame-resistance claims not backed by testing to the relevant standard (EN ISO 14116 index 1, 2, or 3) for the actual finished garment — after-market screen printing and heat-transfer branding is a very common source of failure here, since the ink or transfer film itself can be flammable even when the base fabric passed on its own. Second, general innocuousness requirements under EN ISO 13688 — restrictions on azo dyes, chromium VI, nickel release, and permissible pH range for skin contact — not verified for imported fabric, particularly on brightly dyed or heavily treated workwear fabrics sourced purely on price. Third, sizing and ergonomic requirements tested on a mannequin in a neutral standing pose rather than the working postures the standard actually specifies, which produces coveralls that look correctly sized on the rack but restrict movement across the shoulders or knees the moment they’re worn on the job. A fourth issue is coveralls marketed as “flame-resistant” using the lower-bar EN ISO 14116 index when the buyer’s actual working conditions call for a sustained-exposure heat-and-flame standard — a mismatch that isn’t a manufacturing defect at all, but a specification error that only surfaces when the garment is relied on for a hazard it was never rated against.

Labeling Requirements

Garment labels must show manufacturer, size (using the standard’s body-measurement pictogram rather than only S/M/L, since fit varies significantly by region of manufacture), the EN ISO 13688 reference plus any specific hazard standard achieved (such as an EN ISO 14116 index), care/wash instructions, and fibre content. Where flame-resistant properties are claimed, the flame-standard pictogram and index must appear specifically, and any after-market printing, embossing, or reflective tape added to an FR garment should be separately confirmed not to compromise the flame rating, since standard labeling does not automatically extend to customization applied after the original fabric test. Where a higher heat-and-flame standard applies rather than simple limited flame spread, the label should reference that specific standard (such as ISO 11612) rather than EN ISO 14116 alone, since the two represent genuinely different levels of protection and buyers frequently can’t tell them apart from the garment’s appearance. Reflective or contrast-trim workwear that combines general coverall requirements with a high-visibility claim should carry both sets of markings independently — an EN ISO 13688 general-requirements coverall with reflective tape sewn on is not automatically an EN ISO 20471-compliant garment unless the combined product has actually been tested and marked against that standard as well.

Packaging & Documentation

Typical Gaps We Find

The most common defect is an FR-labeled coverall where the flame test was performed on plain, undecorated fabric before branding or reflective tape was added, with no retest ever run on the finished, decorated garment that’s actually shipped. Innocuousness screening missing entirely for imported fabric lots is the second most frequent gap, particularly on bright orange and yellow high-visibility-adjacent dye colours that carry a higher risk of restricted substance use. We also regularly find sizing charts copied from a different regional standard that don’t match the actual cut of the garment once measured against the working-posture requirements — a fit problem that only shows up once the coverall is actually worn on the job rather than tried on standing still in a shop. Specification mismatches round out the list: coveralls procured under a generic “FR” description for workers with regular flame or radiant-heat exposure, when what was actually supplied and tested was the lighter limited-flame-spread standard intended for incidental contact rather than sustained exposure.
