AMERICAN LEGISLATION

ANSI/ISEA 105

ANSI/ISEA 105 “American National Standard for Hand Protection” defines levels for the mechanical, thermal, chemical and dexterity performance of hand and arm personal protective equipment (PPE).

The American National Standards Institute (ANSI) and the International Safety Equipment Association (ISEA) have developed guidelines that help assure the safety of consumers. Where appropriate the ANSI performance rating is included to give a better understanding of the level of protection a speci c product offers.

CUT PROTECTION

In the US market, the standard is ASTM F1790 (first version: 1997; current version: 2005). This method was adopted by ISO in 1999 as an international standard: ISO 13997.

This method allows cut resistance to be indicated by the required weight applied to the cutting blade to cut through the test sample. An ANSI level is determined by how much weight is needed to cut through a given material with 25 mm of blade travel when testing to ASTM F1790-97 or 20 mm of blade travel when testing to ASTM F1790-05. Levels range from 0 to 5, with 5 providing the highest level of cut resistance. The table below shows the ANSI performance levels to assist in correct glove selection.

CUT TESTING MACHINES

A CPP tester is used to determine the cut levels of a glove by the ASTM F1790-97 method, and when testing for ASTM F1790-05 method a CPP tester or a TDM machine could be used. Various weight loads are applied to the blade as it travels across the glove material.

ABRASION PROTECTION

The Taber Abrasion Test is an ASTM D3389 abrasion test. This test method determines the resistance to abrasion of rubber, and plastic-coated materials.

A four-inch circular test specimen is mounted on a horizontal-axis platform while being abraded to failure under a specified vertical weight load (of 500 or 1000 grams) by the sliding rotation of two vertically oriented abrading wheels. The abrading wheels are comprised of vitrified clay and silicon carbide abrasive particles. The results, recorded in revolutions, are classified by ANSI/ISEA 105-2000 Hand Selection Criteria as follows:
