A sample costs a few dollars and a week of patience. A container of the wrong glove costs a season. Chainmail is a product you cannot assess from a photograph, because the protection lives in the weld between two rings, the weight of the mesh on the hand, and the way the strap behaves on the five-hundredth opening. This guide explains what a supplier can send, what each type of sample proves, how to inspect and wear-test it, and how to turn an approved sample into a production standard that both sides can hold each other to.
Most specification disputes trace back to a sample that was approved informally. A glove arrived, someone tried it on, it felt right, and production was released. Six weeks later the strap colour is different, the cuff is fifteen millimetres shorter, and the rings weigh less than the approved pair. Nothing dishonest happened; the sample was simply never written down as a standard.
Formal sample approval fixes that in four steps. The sample is inspected against a written checklist, the results are recorded, the sample is signed and dated, and one copy is retained by each party as the golden sample. From that point, production is measured against an object rather than an email thread, and any change becomes a documented deviation rather than a discoverable surprise.
Sample type |
How it is produced |
What it proves |
What it cannot prove |
Stock sample |
Pulled from existing finished inventory |
Current construction, general finish, weight and fit |
Whether production will match it after a strap or wire change |
Custom sample |
Built to your specification, sometimes as a one-off pilot |
That the factory can execute your requested specification |
Batch consistency, which needs more than one unit |
Pre-production sample |
First article from the actual production batch |
That the line, not just the development bench, can hit the standard |
Long-term durability, which only field use reveals |
A serious buyer asks for the third. Stock and custom samples answer whether the product exists; the pre-production sample answers whether the batch you are about to pay for will be the product you approved.
Item |
Common practice |
What to confirm in writing |
Sample unit price |
Charged at or near the bulk unit price, sometimes with a small handling element |
Whether the fee is credited against the bulk order and at what minimum quantity |
Freight |
Collect on your courier account, or prepaid and added to the invoice |
Which incoterm applies and who pays duty on samples |
Custom sample setup |
Charged separately where new jigs, labels or straps are involved |
Whether the setup is refundable and whether it is amortised later |
Sample lead time |
Stock items in days, custom items in weeks |
The date the sample leaves the factory, not the date it is promised |
Documentation |
Test reports and declarations sent with or before the sample |
That the documents cover the exact model and grade shipped |
Buyers sometimes push hard on a free sample, which is a false economy. A supplier who gives away samples tends to give away specification detail too. Paying for the sample and getting the documentation pack with it is usually the better trade.

Inspection should be repeatable, so that two buyers looking at the same glove reach the same conclusion. The twelve checks below cover the properties that determine whether a chainmail glove performs in a food plant.
Check |
Method |
Acceptance criterion |
Model and finger count |
Compare with the order specification |
Exact match, including cuff length |
Wire diameter |
Micrometer on three rings, away from welds |
Within the stated tolerance, typically plus or minus 0.02 mm |
Ring inner and outer diameter |
Vernier or ring gauge on five rings |
Matches the declared ring specification |
Ring density |
Count rings in a one centimetre square at palm, back and finger |
Consistent across the three zones |
Weld integrity |
Magnify twenty welds, pull test three rings by hand |
No open lap joints, no movement under pull |
Wire ends |
Cotton swab along cuff edge and finger tips |
No snagging on the swab |
Strap and closure |
Open and close fifty times, load the strap |
No fraying, no buckle slip, no stitch failure |
Strap colour coding |
Compare with the size and colour chart |
Correct colour for the size |
Weight |
Scale, by size |
Within the declared weight band |
Fit |
Wear test on a representative hand |
Fingers reach the tips, no bunching at the palm |
Finish |
Visual under a light box |
No stains, no drawing residue, no bent rings |
Marking and packaging |
Check label, size marking, polybag and carton |
Matches the approved artwork and packing spec |
Not everything needs a laboratory. Three tests you can run yourself produce evidence that a datasheet never will. The salt immersion test, using a three percent solution for twenty-four hours, exposes grade substitution quickly, because 304 will stain and 316L will not. The cleaning cycle test, running the glove through your own wash and sanitise protocol three times, exposes strap degradation and coating failure. The snag test, dragging the glove across a stainless work surface and a bin edge, exposes open ring joints and unfinished wire ends.
Record the results with photographs and dates. A supplier confronted with a photograph of an opened ring at the finger tip after a snag test will correct the specification rather than argue about it.
The most informative sample test is the one that happens on a real shift. A structured wear trial converts subjective comfort into usable data.
Trial element |
How to run it |
What it reveals |
Participant selection |
Five to ten workers covering at least three hand sizes and both dominant hands |
Whether the size range and ambidextrous build suit your workforce |
Duration |
Two to four weeks of normal production, minimum twenty hours per glove |
Fatigue, strap wear, ring deformation under real force |
Task coverage |
Include the highest-force task in the plant, not only light trimming |
Whether the wire gauge is adequate |
Daily log |
Comfort score, slippage, strap loosening, hand fatigue, any snag incidents |
Patterns that a single day of use would hide |
End-of-trial inspection |
Repeat the twelve-point check on returned gloves |
Wear points and remaining service life |
Comparison arm |
Run the incumbent glove alongside under the same conditions |
A defensible basis for switching |
The step that converts a sample into a supply standard is documentation, and it takes less than an hour. Photograph the glove from four angles with a scale in frame. Record the measured wire diameter, ring dimensions, weight and cuff length. Note the strap type, colour and buckle model. Attach the label and packing photographs. Sign and date the record, and have the supplier sign the same document. Keep one sealed sample and ask the supplier to keep the matching one.
The golden sample record then becomes a clause in the purchase order: production must match the retained sample, and any deviation requires written approval before shipment. That clause is enforceable in a way that a specification sheet alone rarely is.
Mismatch |
Root cause |
Prevention |
Lighter glove on arrival |
Wire substitution after sample approval |
Golden sample clause plus incoming weight check by size |
Different strap colour |
Strap batch substitution when stock ran out |

State cuff length with a tolerance in the purchase order |
Pressed rings instead of welded |
Cost reduction not communicated |
Weld inspection on every incoming lot, three rings per glove |
Different label or carton |
Artwork approved by email, not by proof |
Approve a physical printed proof before production |
Size drift across batches |
No jig control on the assembly bench |
Measure three gloves per size per lot against the size chart |
Hebei Linchuan Safety Protective Equipment Co., LTD supplies samples from stock for the five finger short glove, the long cuff glove with a 20 cm sleeve and the three finger glove, and builds custom samples to specification when a strap, size or marking change is required. Sample fees are credited against the bulk order above the agreed quantity, and the documentation pack for the exact model is sent with the sample rather than after the order.
To make the sample useful rather than decorative, tell us the application, the highest-force task in your plant, the hand sizes you need to cover and the market you will sell into. We will send the closest matching construction, the measured specification sheet, and the certificate and test documents that apply, so that your trial begins with the paperwork already in place.
