THE TESTS HANVO CONDUCTED ON HAND PROTECTION PRODUCTS

The overview below details the comprehensive testing procedures applied to HANVO safety glove products, including the testing equipment, methodologies, and the international safety standards with which they comply.

Equipment: Maxi-artindale Abrasion and Pilling Tester

Test Methods: Take the palm position of the glove as a sample, grind it on standard sandpaper. Count the number of revolutions when the glove is worn out.

Standard: EN 388:2016+A1:2018

Equipment: Blade Cut Resistance Tester

Test Methods: The test sample is placed on the machine. The blade is lowered slightly and touches the sample. The counter is set to zero. When the rotating blade penetrates the test sample, the machine will automatically stop. The number of cycles displayed on the workbench screen can be used to calculate the cutting index, which is used to measure the blade cut resistance of the material.

Standard: EN 388:2016+A1:2018

Equipment: SATRA Tensile Tester

Test Methods: Take the palm position of the glove as a sample，tear it apart by pulling force, calculate the required force value and judge the level of tear resistance of the product.There are 4 levels of EN388.

Standard: EN 388:2016+A1:2018

Equipment: TDM Tomodynamometer Cut Resistance Tester

Test Methods: The sample was cut by the blade under pressure in the palm of the glove, and the distance required for the blade to cut through the sample at different forces was tested.

Standard: ISO 13997 (EN388:2016) ASTM F2992-15 (ANSI/ISEA 105-2016)

Equipment: Agilent gas chromatography mass spectrometry analyzer

Test Methods: Take the palm position of the glove (including the middle finger), cut it into pieces of 10mm*10mm size, add the corresponding measured extraction solution, and shock it with ultrasonic wave for 30 minutes to test the content of DMF in the solution. The eu standard requires <1000ppm.

Standard: EN16778:2016

Equipment: Skid proofer tester

Test Methods: Use a fixed gram weight to press the middle finger of the glove and test how much force to pull the glove to determine the anti-skid performance of the product.

Standard: Midori Anzen standard Internally controlled standard

Equipment: Yarn wrap reel

Test Methods: Monitor yarn weight under 100m length to ensure yarn performance meets requirements.

Standard: Internally controlled standard

YARN TESTING

Rest assured, the tests listed below represent only a portion of the rigorous evaluations performed to guarantee HANVO’s superior product performance. In addition to testing our PPE hand protection products, our in-house laboratory also conducts comprehensive assessments on the raw materials used in work glove production. These evaluations include, but are not limited to, the following tests:

Yarn Count Test

Evaluates the yarn's linear density by measuring its weight, ensuring that performance specifications align with internal quality standards.

Yarn Twist Test

Assesses the number of twists per unit length in the yarn to determine its structural integrity and tensile behavior.

Yarn Strength & Elongation Test

Measures the tensile strength and stretchability of the yarn by applying force to a fixed-length sample until it breaks, indicating its resistance under stress.

At HANVO, the safety of our users is paramount. That’s why every pair of our hand protection products undergoes a rigorous quality inspection to ensure maximum protection in hazardous working environments. Our customers trust us to deliver consistently high-performance safety gloves they can rely on.
