ASTM D5250: Dusting Powder, Ageing and PVC Glove Limits
Poly(vinyl chloride) exam gloves occupy an awkward spot in the modern clinic cupboard. They are the least expensive line on many price lists, they have a documented thickness problem against concentrated chemistry, and yet they remain useful for short, dry, low risk contact where the glove is changed several times an hour.
The specification behind them is ASTM D5250, titled standard specification for poly(vinyl chloride) gloves for medical application. It is a companion document to the rubber exam glove specification rather than a variant of it, and its own scope says so: D5250 describes itself as similar to D3578. The similarity is real but incomplete, and the differences are the parts a buyer needs.
What does ASTM D5250 cover?
Clause 1.1 covers poly(vinyl chloride) gloves used in medical examinations, diagnostic and therapeutic procedures and in handling contaminated medical material. Clause 1.2 adds the configurations: gloves that fit either hand, paired gloves, gloves by size, and packaged sterile, packaged nonsterile or bulk nonsterile supply.
Clause 1.3 is the exclusion worth remembering. The specification does not cover two dimensional heat sealed poly(vinyl chloride) gloves, which removes a class of formed, welded products from the medical glove framework. If a supplier cannot say which construction their glove is, that question alone can decide whether D5250 applies.
The material clause is deliberately open. Any poly(vinyl chloride) polymer compound may be used that allows the finished glove to meet the specification, which means the standard regulates performance rather than recipe. That is also why the plasticiser conversation sits outside the glove specification: PVC medical products are frequently plasticised, and the literature on plasticiser exposure from PVC medical devices stretches back decades, including a critical review of DEHP exposure published in the American Journal of Industrial Medicine. The glove specification does not adjudicate that chemistry, and a buyer looking for a plasticiser position has to ask for it directly.
What is different about the ageing test?
Ageing is where the two exam glove specifications visibly diverge. Both use Test Method D573 and both apply the same six month rule, but the exposure is not the same length.
| Item | D5250 (poly(vinyl chloride)) | D3578 (natural rubber) |
|---|---|---|
| Ageing exposure | 70 C plus or minus 2 C for 72 h plus or minus 2 h | 70 C for 166 h plus or minus 2 h, or 100 C for 22 h |
| Acceptance after ageing | No tackiness, exudation or other deterioration, and physical requirements still met | Tensile strength and elongation at break not below the table values |
| Gloves over six months old | No accelerated ageing performed | No accelerated ageing performed |
| Protein testing | None | Aqueous extractable protein and antigenic protein |
| Holes | Test Method D5151 | Test Method D5151 |
The shorter exposure is not a lower standard; it reflects how the two materials age. Natural rubber is vulcanised and continues to change over time, so the referee condition runs longer to project a multi year shelf life. PVC formulations soften and can exude plasticiser, which is why the acceptance criterion names tackiness and exudation explicitly rather than concentrating only on tensile numbers. A clinic that stores glove cartons in a hot service corridor is testing that second failure mode for real.
What are the acceptable quality levels?
Sampling is prescribed rather than negotiated. Clause 5.1 requires referee sampling from finished product, after sterilisation where the glove is labelled sterile, inspected under ISO 2859, with inspection levels and acceptable quality levels taken from Table 1 of the specification or set by agreement where the agreed plan is more comprehensive.
| Characteristic | Inspection level | Acceptable quality level |
|---|---|---|
| Freedom from holes | I | 2.5 |
| Dimensions (width, length, thickness) | S-2 | 4.0 |
| Physical requirements, before and after ageing | S-2 | 4.0 |
| Sterility | Not applicable | Tested to the Pharmacopeia |
| Powder residue, powder amount | N=5 and N=2 | Characteristic checks |
Read the holes row carefully, because it is the number that shows up as a complaint. An AQL of 2.5 at inspection level I is a sampling scheme, not a promise that 2.5 percent of gloves have holes. It defines how many defective units a sample of a given size may contain before the lot fails. When a clinic reports a run of perforated gloves, the useful question is whether the sampler used the plan in Table 1 or a looser agreed plan, because the specification allows an agreed plan and requires only that it be more comprehensive.
What do the powder and talc rules say?
Three clauses govern what may sit on a PVC glove. Clause 3.2 allows a lubricant that meets the current U.S. Pharmacopeia requirements for absorbable dusting powder, and permits other lubricants if their safety and efficacy were previously established. Clause 3.3 requires the inside and outside surfaces to be free of talc. Clause 6.1.5 sets a powder residue limit of 2.0 mg for powder-free gloves.
For powdered gloves the specification states a recommended maximum powder limit of 10 mg per square decimetre, measured with Test Method D6124, with the square decimetre calculation taken from the rubber glove specification. The word recommended matters in a procurement conversation: it is the value published in the standard, and a supplier claiming compliance should be able to state which value the lot was measured against.
Which tests are missing compared with latex?
Two thirds of the rubber glove test set carries straight over: freedom from holes under D5151, dimensions under D3767, tensile properties under D412, ageing under D573, powder under D6124. What disappears is protein testing.
The rubber specification measures aqueous extractable protein using the modified Lowry method in D5712 and antigenic protein using the immunological method in D6499, and those protein results are what make latex allergy management a documented exercise rather than a guess. Poly(vinyl chloride) contains no natural rubber protein, so D5250 has no protein clause at all, and the nitrile specification is the same. A clinic moving from latex to vinyl for a specific task is not getting a low protein glove; it is getting a glove where protein was never a variable.
Where do PVC exam gloves fit in a clinic?
The honest answer is shorter than the marketing suggests. A permeation study published in the American Journal of Infection Control tested six glove materials against a 7.5 percent hydrogen peroxide sterilising and disinfecting solution using ASTM F739 methodology. Both the poly(vinyl chloride) and disposable latex examination gloves at 4.5 mil provided less than 30 minutes of protection. A 16.5 mil natural rubber glove lasted eight hours without detectable penetration, and neoprene and nitrile butyl rubber gloves also held through the eight hour test.
Three conclusions survive from that paper. The first is that a 4 mil exam glove of any material is a short contact garment, not a shield. The second is that thickness, not the material name alone, drives the result. The third is that where the task involves a disinfectant, a sterilant or a chemotherapy drug, the choice belongs to the permeation method and not to the price list.
- Suitable - brief examinations, clean supply handling, administrative and reception tasks, food handling where the glove is changed often.
- Not suitable without checking - any sustained contact with disinfectants, hydrogen peroxide, sterilants, solvents or chemotherapy drugs.
- Never a substitute for - a thicker glove tested to the relevant permeation method, or a specification such as D6978 for chemotherapy drugs.
A clinic that stocks vinyl to keep single use costs down should pair it with a heavier nitrile option for the tasks that need one. A 4 mil blue nitrile exam glove covers general examination use, a 6 mil heavy duty black nitrile glove handles rougher work, and a 5 mil fully textured nitrile glove sits between them for wet or slippery handling. Volume buyers ordering across all three can request a bulk quote or start with the wholesale account.
What should a buyer verify on a vinyl glove box?
- The specification and the construction - D5250 applies to dip moulded PVC gloves; two dimensional heat sealed products are outside it.
- The powder statement - powder-free against the 2.0 mg residue limit, or powdered against the recommended maximum.
- The sterility statement - sterile lots are sampled after sterilisation, nonsterile bulk supply is not.
- The date of manufacture - the six month rule determines whether accelerated ageing is even performed.
- The lot number - the only link between a complaint and a test record.
- The supplier - gloves are medical devices in Canada, and the establishment importing them holds a licence to do so.
Storage finishes the job. Heat softens PVC and encourages exudation, so cartons belong on shelving rather than on a floor plate beside a radiator, and stock should rotate oldest first. A glove that met its ageing requirement in a laboratory can still fail the same way in a hot storeroom.
CliniEco Medical supplies exam gloves and the consumables that sit beside them to clinics, long term care homes and laboratories across Canada, with the specification numbers printed rather than implied. The clinic supply range covers glove boxes through to exam room disposables, and wholesale cases are available for higher volume ordering.

Frequently Asked Questions
What is ASTM D5250?
ASTM D5250 is the specification for poly(vinyl chloride) gloves for medical application. It covers PVC gloves used in medical examinations, diagnostic and therapeutic procedures and in handling contaminated medical material, and it sets the performance requirements, the ageing exposure, the powder limits and the sampling rules a finished lot is judged against.
How is ageing tested in ASTM D5250?
Aged samples are exposed at 70 degrees Celsius plus or minus 2 degrees for 72 hours plus or minus 2 hours under Test Method D573. The glove has to withstand that exposure without evidence of tackiness, exudation or other deterioration, and it still has to meet the physical requirements before and after ageing. That 72 hour exposure is shorter than the 166 hour referee exposure used in the latex exam glove specification.
What powder limits does D5250 set?
The specification sets a powder residue limit of 2.0 mg for powder-free gloves, determined with Test Method D6124, and states a recommended maximum powder limit of 10 mg per square decimetre for powdered gloves. A lubricant meeting the current U.S. Pharmacopeia requirements for absorbable dusting powder may be used, and talc is not permitted on the inside or outside surface.
What AQL does D5250 use for freedom from holes?
Table 1 of the specification lists freedom from holes at inspection level I with an acceptable quality level of 2.5. Dimensions and the physical requirements before and after ageing sit at inspection level S-2 with an AQL of 4.0. Powder residue and powder amount are handled as characteristic checks rather than as AQL attributes.
Do PVC exam gloves have a protein limit?
No. Protein testing belongs to the natural rubber specifications, where aqueous extractable protein is measured by Test Method D5712 and antigenic protein by Test Method D6499. Poly(vinyl chloride) contains no natural rubber protein, so D5250 has no equivalent clause, and the same is true of the nitrile specification.
Are vinyl exam gloves a chemical barrier?
Not against concentrated chemistry, and thickness matters as much as material. A published permeation study using ASTM F739 found that a 7.5 percent hydrogen peroxide germicide broke through both poly(vinyl chloride) and disposable latex examination gloves at 4.5 mil within 30 minutes, while a 16.5 mil natural rubber glove held for eight hours.
Which tasks should a clinic keep vinyl gloves for?
Short, dry, low risk contact where the glove is changed frequently: brief examinations, handling clean supplies, reception or administrative tasks where hand protection is about hygiene rather than chemistry. Where the task involves a disinfectant, a sterilant or a chemotherapeutic drug, the glove specification and the permeation data should be checked rather than assumed.
Does ASTM D5250 cover sterile PVC gloves?
Yes. The scope provides for packaged sterile, packaged nonsterile and bulk nonsterile gloves. Sterile lots are sampled from finished product after sterilisation and tested for sterility to the current edition of the U.S. Pharmacopeia, the same approach used in the rubber and nitrile specifications.
