Before ordering, a Canadian buyer should be able to see four things on the supplier documentation: the ASTM test methods the glove is tested against, the acceptable quality limit and inspection level, the freedom-from-holes test result, and the powder and protein statement. A glove order without that paperwork is a glove order you cannot defend if a batch fails at the bench. A routine clinical purchase looks like this 4 mil blue nitrile examination glove, supplied with a specification sheet that names the test methods rather than describing the product in adjectives.
This is the checklist a procurement lead can use on a new supplier, and the questions worth asking on a reorder.
Which test methods should a nitrile glove specification name?
| Property | What the test covers | What to ask for |
|---|---|---|
| Freedom from holes | Water leak test on sampled gloves | Acceptable quality limit and inspection level |
| Dimensions | Length, width and thickness at the specified points | The measured values, not the nominal mil only |
| Tensile strength | Strength before and after ageing | Both the unaged and aged result |
| Powder | Residual powder on the glove | A clear powder-free statement |
| Protein content | Residual protein relevant to sensitisation | The measured limit, not a claim of being latex-free alone |
What does acceptable quality limit actually mean?
It is the worst quality level considered acceptable in a sampling plan, paired with an inspection level that sets how many gloves are checked. A glove at a stated limit is not a promise that every glove is perfect — it is a statement about the batch. Read it with the sample size, because a limit quoted without the inspection level tells you very little. For clinical use, ask what the supplier does when a batch fails the sampling plan, not just what the plan is.
Why does the paperwork matter more than the brand on the box?
Because gloves are purchased in cases and used at the bedside, where a thin patch or a pinhole is the failure that matters and it will not be visible in the box. If a clinician reports a run of tears, the buyer needs the batch code and the test documentation to open a claim. A case of nitrile gloves bought in bulk, such as a 1,000-glove wholesale case, is often stored for weeks before use, so the storage conditions matter as much as the incoming test result.
What should a buyer verify about storage and shelf life?
Nitrile degrades under heat, sunlight and ozone, and the ageing part of the tensile test exists because gloves lose strength over time. Ask for the manufacture date and the shelf life, store cases off the floor and away from windows, and rotate first in first out. A glove that passed at the factory can still fail at the bench if it spent a summer in a hot store room. If your facility holds large volumes, put the manufacture date on the store room sheet.
Which questions are worth asking on every reorder?
Five: has the manufacturing site changed, has the specification sheet changed, is the batch code on the case, what is the manufacture date, and is the size mix still what the units use. The last one is the quiet cost driver — a clinic that orders a comfortable mix of sizes uses fewer gloves than one that keeps ordering the sizes that ran out first.
Make it repeatable: print the compliance log templates, use the same page as your free log generator, and ask a compliance specialist when a result is unclear.

Frequently Asked Questions
What paperwork should come with a nitrile glove order?
The specification sheet naming the test methods, the acceptable quality limit with inspection level, the freedom-from-holes result, and a powder and protein statement.
What is an acceptable quality limit?
The worst quality level considered acceptable in a sampling plan. It applies to the batch, not to every individual glove, so read it with the inspection level.
Does shelf life matter for nitrile gloves?
Yes. Nitrile loses tensile strength with age and heat, which is why the specification includes an aged strength result. Rotate stock first in first out.
What should I check on a reorder?
Any change of manufacturing site or specification, the batch code on the case, the manufacture date, and whether the size mix still matches what the units use.
