What Is Glove Tensile Strength?
Tensile strength is a fundamental mechanical property that determines how much force a glove material can withstand when stretched before breaking. High tensile strength indicates durability, flexibility, and superior resistance to wear and tear—qualities essential for medical, industrial, and laboratory applications.
Why Tensile Strength Testing Matters
- Safety Assurance: Confirms that gloves can withstand expected stress during use.
- Regulatory Compliance: Ensures materials meet ASTM standards for distribution and use.
- Product Development: Helps in material selection and quality control during R&D.
- Market Competitiveness: Demonstrates commitment to high-quality, reliable products.
ASTM D412: The Standard for Rubber and Elastomers
ASTM D412 is the primary standard used for evaluating the tensile properties of rubber and elastomeric materials. Under this method, gloves are cut into dumbbell-shaped specimens and subjected to controlled tension until break. This process provides critical data including:
- Ultimate tensile strength (MPa)
- Elongation at break (%)
- Modulus at specific elongations (e.g., 100%, 200%)
Kiyo R&D Center & Laboratory employs advanced tensile testing machines with digital extensometers to ensure exact strain measurements and accurate results in full compliance with ASTM D412 protocols.
ASTM D6319: Specialized Testing for Nitrile Examination Gloves
ASTM D6319 focuses specifically on nitrile rubber medical examination gloves, outlining both physical requirements and test procedures. Tensile strength testing under this standard ensures gloves maintain integrity during medical procedures and meet FDA performance thresholds.
Key aspects include:
- Minimum tensile strength for unaged and aged gloves
- Elongation requirements before and after accelerated aging
- Visual and dimensional inspection standards
At Kiyo R&D Center & Laboratory, our aging chambers and mechanical testing systems are calibrated for precise execution of ASTM D6319. We provide comprehensive testing for manufacturers seeking certification or quality assurance for nitrile gloves.
