Nitrile glove specifications can feel overwhelming when you first look at a product sheet. Mil thickness, gram weight, AQL, ASTM certifications, and powder-free options create a vocabulary that procurement teams often skip over in favor of brand name or price alone. This is a mistake. The specifications tell you exactly what you are buying, whether a glove will hold up under the conditions you will use it in, and whether you are paying for something you do not need.
This guide breaks down the most critical nitrile glove specifications. By the end, you will understand what each number means, how to compare gloves across suppliers, and how to match the right specification to your operation's actual needs. This is not about brand. It is about reading the spec sheet and making a data-driven choice.
The Two Numbers That Matter Most: Mil Thickness and Gram Weight
When evaluating a nitrile glove, you will see two measurements for thickness. The first is mil thickness. A mil is one thousandth of an inch. A typical nitrile food service glove runs 2.0 to 3.5 mils thick. A medical exam glove runs 3.5 to 5.0 mils. An industrial chemical-resistant glove runs 5.0 to 8.0 mils or more.
The second measurement is gram weight, typically given as grams per pair. A gram weight measurement is more reliable than mil thickness alone because it accounts for glove size and the actual amount of nitrile material in the glove. Two manufacturers might both claim 3.5 mils, but if one is padding the measurement and the other is not, the actual protection you get differs. Gram weight reveals the truth.
Typical gram weights for common applications are as follows. Food service gloves: 2.5 to 3.5 grams per pair. Medical exam gloves: 3.5 to 5.0 grams per pair. Industrial and chemical-resistant gloves: 5.0 to 8.0 grams per pair or heavier. When you are comparing quotes from different suppliers, always ask for gram weight. It is the most honest specification.
ASTM Standards: D6319, D5250, D6978, and What They Protect Against
ASTM standards are the backbone of glove compliance. They define testing requirements for durability, puncture resistance, chemical resistance, and other performance characteristics. The most common standard for nitrile gloves is ASTM D6319. This standard covers nitrile examination gloves and defines tensile strength, elongation at break, tear strength, and puncture resistance. If your supplier is selling nitrile gloves for food service or medical use, they should have ASTM D6319 testing data.
ASTM D5250 covers poly gloves and latex gloves. If you see this standard on a nitrile glove spec sheet, it is a mistake or a non-nitrile product. ASTM D6978 is used for chemotherapy and hazardous drug handling gloves. These are thicker and tested for cytotoxic permeation. Unless your operation involves pharmaceutical handling, you do not need D6978 rated gloves.
For food service, the relevant compliance standard is FDA 21 CFR 177, which covers indirect food contact. Your nitrile glove supplier must be able to provide FDA registration documentation showing that the glove material meets this standard. If a supplier cannot provide that documentation, your operation may face FDA inspection issues.
AQL Ratings and What They Really Mean
AQL stands for Acceptable Quality Level. It is a sampling inspection standard that defines the maximum percentage of defective gloves allowed in a batch. AQL 1.5 means that in a sample of 1,250 gloves from a production batch, no more than 15 defective units are acceptable. AQL 2.5 means up to 25 defects are acceptable in the same sample size.
Medical exam gloves typically have AQL 1.5. This is stricter. Food service gloves often have AQL 2.5 or higher. Industrial gloves may not specify AQL at all. The lower the AQL, the higher the quality control cost for the manufacturer. You will pay more for AQL 1.5 than AQL 2.5. But if your operation is processing high-volume food orders or handling sterile environments, the investment in AQL 1.5 is worth the defect rate reduction.
Choosing the Right Glove by Application
Not all nitrile gloves are created equal. The right choice depends on how your operation uses them.
Food Service Gloves
Food service operations need gloves rated for indirect food contact (FDA 21 CFR 177). Typical specifications are 2.5 to 3.5 grams per pair, 2.0 to 3.0 mils thick, AQL 2.5 to 4.0, and powder-free with touchscreen compatibility. The thinner profile reduces hand fatigue over long shifts. Cost efficiency is important because food service operations go through high volume. A food prep worker will use 20 to 30 pairs per shift. Dual-sourcing this category protects against tariff shocks that can add 100+ percent to glove costs overnight.
Medical and Exam Gloves
Medical exam gloves require higher standards. Typical specifications are 3.5 to 5.0 grams per pair, 3.5 to 5.0 mils thick, AQL 1.5, and latex-free certification. These gloves undergo ASTM D6319 testing for tensile strength, puncture resistance, and tear resistance. They may carry additional certifications such as CE marking (Europe) or TGA approval (Australia). Medical gloves cost more because the material quality and quality control are stricter. Use them when the risk of contamination or cross-exposure is high.
Industrial and Chemical-Resistant Gloves
Industrial operations handling chemicals, oils, or harsh materials need thicker gloves with higher puncture and chemical resistance. Typical specifications are 5.0 to 8.0 grams per pair, 5.0 to 8.0 mils thick, and often textured or flock-lined for better grip. Many are rated for specific chemicals under ASTM D6978 or equivalent. Cost is secondary to safety. One tear or puncture in an industrial setting can create liability. Buy the specification that matches your chemical exposure profile.
Common Procurement Mistakes to Avoid
Mistake 1. Overspecifying. Many procurement teams buy medical-grade gloves (AQL 1.5, 4.0 grams) for food service operations that only need AQL 2.5, 3.0 gram gloves. This inflates cost by 30 to 50 percent with no operational benefit. Match the specification to the actual use case.
Mistake 2. Ignoring gram weight variation. Two suppliers might both quote 3.5 mils and claim ASTM D6319 compliance, but one delivers 2.8 grams per pair and the other delivers 3.2 grams per pair. The gram weight difference indicates the actual amount of material in the glove. Do not assume mil thickness alone.
Mistake 3. Not testing samples before volume commitment. Request a sample production run before signing a large contract. Test the gloves in your actual operating conditions. Does the seal hold during high-volume food prep? Do they tear during industrial handling? A $500 sample order now prevents a $50,000 problem later.
Mistake 4. Single-sourcing. When tariffs hit a country of origin, prices on nitrile gloves from that country can jump 100 percent overnight. Gloves are one of the highest-tariff categories in current trade. If you source from a single factory in a single country, you have no fallback. Dual-source the category so you can shift volume when tariffs change.
What to Ask Your Supplier
When evaluating nitrile glove suppliers, ask these specific questions and require written documentation.
What is the gram weight per pair?
Do not accept only mil thickness. Insist on gram weight specifications and the test data to back them up.
What ASTM standard was used for testing?
For food service, confirm ASTM D6319 and FDA 21 CFR 177 compliance. Ask for test reports from an independent lab, not the supplier's internal testing.
What is the AQL rating?
Ask for written AQL certification and the batch test data. Understand that AQL 1.5 costs more than AQL 2.5, and make a conscious choice about which you need.
What is your FDA registration number?
For food contact gloves, your supplier must have FDA registration. Verify the registration number in the FDA database.
Can you provide production consistency data?
Ask for tensile strength and tear resistance data across the last 10 production batches. Consistency matters more than a single perfect test.
