1. Defining ANSI and ISEA
When you see a safety standard like ANSI/ISEA 105, it refers to a set of guidelines developed and approved by two key organizations in the safety world:
- ANSI: American National Standards Institute
- ANSI is a private, non-profit organization that oversees the development and use of thousands of standards in the United States. They do not write the standards themselves. Instead, they provide a rigorous framework to ensure the standards-writing process is open, balanced, and consensus-driven by all stakeholders (manufacturers, users, government, etc.).
- ANSI is the approving body that gives the standard its “American National Standard” designation.
-
- ISEA is the trade association for the manufacturers of safety equipment. They serve as the official organizing body that manages the technical committee responsible for writing, updating, and publishing the standard.
- ISEA is the developer of the safety standard.
2. What is ANSI/ISEA 105?
ANSI/ISEA 105: American National Standard for Hand Protection Classification is the definitive U.S. voluntary consensus standard for classifying and testing the performance of protective gloves and arm sleeves.
This standard provides a uniform system for manufacturers to test their products. It classifies protection levels against a broad range of workplace hazards, including:
- Mechanical Hazards: Cuts, abrasion, puncture, and needle stick.
- Chemical Hazards: Permeation and degradation.
- Thermal Hazards: Heat, flame, and cold.
The standard uses specific rating scales (e.g., A1 to A9 for cut resistance) to quantify how much protection a glove provides, moving the process beyond subjective descriptions like “medium-duty.”
3. Introducing ANSI/ISEA 105-2024
The latest revision, published in late 2024, is the 6th edition of the hand protection standard. Its primary goal is to improve consistency and simplify PPE selection.
The 2024 standard applies to a broader range of products, including sleeves and other arm protection.
4. Key Differences and Updates in the 2024 Edition
While the underlying test methods and performance level scales (e.g., the grams of force required for an A6 cut rating) largely remain the same, the 2024 revision introduced two significant changes:
A. The New Standardized Pentagon Pictogram (The Biggest Change)
Manufacturers are now required to use a single, unified pentagon-shaped badge on the product label to display the key mechanical protection ratings.
| Position on Pentagon | Protection Property | Rating Scale |
| Top Center | Cut Resistance | A1 to A9 |
| Left Side | Abrasion Resistance | 0 to 6 |
| Right Side | Puncture Resistance | 0 to 5 |
- Why it Matters: Before this update, manufacturers used varying symbols or multiple individual markings. The new pentagon standardizes the look across all brands, allowing workers to compare gloves instantly and with confidence. If a property is not tested or not applicable, an “X” is placed in that section of the pentagon.

B. Increased Emphasis on Conformity Assessment
The 2024 standard now places a stronger requirement on manufacturers to validate and verify the ratings they claim, often requiring third-party testing. Specifically, the standard references ANSI/ISEA 125-2021, which governs how this validation and verification must be conducted.
C. Removed Properties (For Simplicity)
Previous sections on testing for vibration reduction and dexterity were removed to ensure the ANSI/ISEA 105 standard focuses purely on protective classifications (mechanical, thermal, chemical resistance) rather than subjective or ergonomic features.
