A pair of work gloves comes out of the case with a little shield stamped on the cuff and four to six characters next to it — something like 4X43D or 2121A. Most buyers glance at it, decide bigger numbers mean a better glove, and move on. That's the wrong read, and it's the reason we get calls from safety managers who bought a "4" glove and still had a hand injury in week three.

That shield is the EN 388 mark. It's the European standard for gloves against mechanical risks, and it shows up on a huge share of the gloves sold in the US because most factories certify to it regardless of where the glove ships. We've been making gloves at G & F Products since the 1980s, and we test to both EN 388 and ANSI/ISEA 105. Here's how to actually read the stamp — and how the two standards line up, which is where most of the confusion lives.

The shield, position by position

Under the current revision, EN 388:2016+A1:2018, the mark carries up to six characters. They are always in the same order, and each position is a different test:

So a glove marked 4X43D reads as: abrasion level 4, coup test not applicable, tear level 4, puncture level 3, ISO 13997 cut level D. Five separate results, not a score. The single most common mistake we see is buyers averaging the string in their head and comparing gloves on the total.

What each number is actually worth

The levels aren't linear, and the jumps between them are much bigger than the digits suggest.

Look at abrasion. Going from level 3 to level 4 isn't a 33% improvement — it's 2,000 cycles to 8,000 cycles, four times the wear life. That gap is the difference between a glove your crew replaces twice a week and one that lasts the month. If you're buying for a high-wear job like pallet handling or masonry, position 1 is the number to negotiate on, and it's the one buyers ignore most.

The two characters people misread

X is not zero. X means the test wasn't performed or doesn't apply to that material. 0 means the glove was tested and failed to reach even the lowest level. An X in the coup-test position is usually a good sign, not a bad one — it typically means the material was so cut-resistant that it dulled the circular blade during testing, which invalidates that method and forces the lab to use the straight-blade ISO 13997 test instead. Gloves with high-performance fibers routinely show X in position 2 and a strong letter in position 5.

Impact is the other oddity. Position 6 shows P for pass or nothing at all. There's no failing grade — a glove without impact protection simply has no sixth character. If you need back-of-hand protection for oil and gas or heavy equipment work, "no letter" means "no protection," not "not great."

EN 388 letters vs. ANSI cut levels

This is the crosswalk buyers ask us for constantly. The two standards now use the same straight-blade test principle — ISO 13997 in Europe, ASTM F2992 in the US — so they measure the same thing in different units: newtons versus grams of cutting force. Roughly, one newton is about 102 grams of force.

Here's the part that catches people out: F is the top of the EN 388 scale, but it only reaches ANSI A6. ANSI/ISEA 105 runs to A9, which is 6,000 grams and up — roughly double what an F-rated glove has to survive. So a European glove marked "F" is genuinely high-performance, but it is not the equivalent of the highest-rated cut gloves on the US market. If your hazard assessment landed on A7 or above, an EN 388 letter alone can't confirm you're covered.

Treat this table as a translation aid, not an equivalency certificate. The standards use different sample conditioning and reporting rules, and neither body recognizes the other's rating as a substitute. For picking a level against a real hazard, our guide to ANSI cut levels A1–A9 walks through the job-matching logic in detail.

What the stamp doesn't tell you

EN 388 covers five mechanical properties. It says nothing about grip, dexterity, heat, chemical permeation, or fit — and those are what determine whether the glove gets worn. A D-rated glove in a drawer protects nobody.

Three things the mark leaves out that we'd check before the numbers:

• Coating. The palm coating drives grip in oil, water, or dry conditions, and it's independent of the cut rating. Our breakdown of nitrile, polyurethane, latex, and PVC coatings covers which one suits which job.
• Shell gauge. An 18-gauge liner and a 10-gauge liner can carry the same cut letter and feel like completely different gloves. See what glove gauge actually means.
• Fit. A loose glove snags in pinch points and gets pulled off. Sizing is not standardized across brands — our sizing guide explains why "large" means four different things.

And the mark tells you nothing about the glove's condition after week two. Abrasion level 4 describes a new glove. Once the coating glazes over or the liner thins at the fingertips, the rating on the cuff is a historical record, not a current one.

How we'd read a cuff stamp

Working order, fastest to slowest: check position 5 first and confirm the letter clears your hazard assessment. Then check position 1, because abrasion determines how long that protection actually lasts. Then look at whether position 6 is blank, if impact is in scope for the job. Positions 2, 3, and 4 are worth a glance but rarely change a purchase decision on their own.

If a supplier can't produce the test report behind the stamp, treat the stamp as marketing. We publish ours.
