1.1
This test method is used for evaluating finger dexterity while wearing gloves.
1.1.1
This test method covers procedures in which the wearer picks up small objects between the thumb and index finger.
1.2
This test method is suitable for evaluating gloves and other forms of hand protection that allow the wearer to pick up small objects between their thumb and index finger.
1.3
This test method does not address all effects of glove use on hand function. Other methods should be considered to evaluate the effects of gloves on grip, tactility, and other hand functions of interest.
Note 1:
This test method may not apply to all glove types or applications.
1.4
The values stated in SI units or in other units shall be regarded separately as standard. The values stated in each system must be used independently of the other, without combining values in any way.
1.5
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
====== Significance And Use ======
5.1
The test method is intended to provide a quantitative measurement about the effect of gloves on wearer finger dexterity by comparing the times required to perform a simple task with and without gloves.
5.2
This test method does not discriminate all glove effects on wearer hand function or apply to all glove types and applications. Additional evaluations or tests representative of the glove use application are recommended to determine the overall impact of gloves on wearer hand function.
5.2.1
Test Method
F2961
provides an assessment for the impact of gloves’ grip by measuring the torque force associated with turning a cylindrical object both with and without gloves.
5.2.2
Clause 6.2 of BS EN 420 assesses gloved tactility by determining the diameter of a metal pin that can be picked up off a flat, smooth surface and grasped.
5.3
Results from this test can be influenced by many factors, including relative fit of the gloves and the age, gender, and general health conditions of the subjects. Exercise care when comparing the results using different subjects.
