Study Notes

Glove Performance Requirements

ASTM F 2010 Standard Test Method is used to evaluate glove effects on wearer hand dexterity using a modified pegboard test with stainless steel pins on a medium knurled 30-degree surface.
The average percent of barehanded control shall not exceed 220 percent.

Glove Donning Test

Gloves are tested for ease of donning.
The whole glove shall have a dry hand donning time not exceeding 10 seconds.
The whole glove shall have a wet hand donning time not exceeding 30 seconds.
There shall be no detachment of the inner liner or moisture barrier.
There shall be full insertion of all digits.

Liner Retention Test

Gloves are tested for retention of the glove liner.
Liner retention is evaluated using locking forceps and a force-measuring gauge.
Each digit shall be inspected for indication of detachment of inner liner and/or moisture barrier.
Failure of any digit of any glove constitutes failure.

Grip Test

Gloves are tested for grip.
Each specimen glove pair is tested as a complete set of gloves.
The pulling device is a 3.2 cm diameter fiberglass pole attached to an overhead calibrated force measuring device.
Each pair of gloves shall not have a drop of more than 30 percent from the peak pull force value.

Overall Liquid Integrity Test

Gloves are tested for resistance to leakage.
The test subject immerses the donned specimen(s) straight down into the surfactant-treated water for 5 minutes.
The test subject flexes the specimen in a gentle, complete fist-closing motion every 10 seconds.
The appearance of any watermark on the inner glove after testing constitutes leakage and failure.

Torque Test

Torque testing is evaluated using a 15⁄8 in. diameter solid acrylic cylinder on a calibrated digital torque meter.
The average maximum twisting force with gloves over three trials for each size is calculated, recorded, and reported.
The average twisting force shall be compared with the barehanded control value.
The whole glove shall have an average percent of barehanded control not less than 80 percent.

Hood Performance Requirements

Hoods are tested for thermal insulation using the Thermal Protective Performance (TPP) Test.
Hoods shall have an average TPP rating of not less than 20.0.
Hoods are individually tested for resistance to heat and thermal shrinkage.

Description

Learn about the grip test requirement for gloves according to ASTM D5510 standard. Understand the testing procedure involving a fiberglass pole and force measuring device, ensuring that pulls are downward and perpendicular to the ground until surface degradation occurs.
