(Test Method)Standard Test Method for Measuring Cut Resistance of Materials Used in Protective Clothing
Standard Test Method for Measuring Cut Resistance of Materials Used in Protective Clothing
SIGNIFICANCE AND USE
5.1 This test method assesses the cut resistance of a material when exposed to a cutting edge under specified loads. Data obtained from this test method can be used to compare the cut resistance of different materials.
5.2 This test method only addresses that range of cutting hazards that are related to a cutting action across the surface of the material. It is not representative of any other cutting hazard to which the material may be subjected such as serrated edges, saw blades or motorized cutting tools. Nor is it representative of puncture, tear, or other modes of fabric failure.
SCOPE
1.1 This test method covers the measurement of the cut resistance of a material when mounted on a mandrel and subjected to a cutting edge under a specified load using the Cut Protection Performance (CPP) Tester.
1.1.1 This procedure is not valid for high-porosity materials which allow cutting edge contact with the mounting surface prior to cutting.
1.1.2 Test apparatus may have limitations in testing materials with a thickness greater than 3 mm or having a high frictional coefficient such as elastomers.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.

an applied load and measure the distance of blade travel required to cut through the specimen. This
test method calculates the load required to cut through different specimens at 25.4 mm [1 in.] blade
travel. This calculated load, defined as a rating load, can be used to compare the cut resistance of
materials.
The original F1790-97 test method defined a commercially-available apparatus known as the Cut
Protection Performance Tester (CPP). In an attempt to harmonize F1790/F1790M with ISO 13996
(another international testing standards for measuring cut resistance) and improve the test method, the
scope of the test method was changed in F1790-05 to allow the use of other cut testing equipment,
specificallytheTomodynamometer(TDM-100)andamodificationtotheCPParmcalledtheModified
CPP (mCPP). The revision addressed issues related to measurement of high frictional coefficient
materials like elastomers, specimen mounting, rating load calculation, and other procedures to
harmonize with ISO 13997:1999. After further round-robin evaluation by the subcommittee, it was
demonstrated that the revisions to the test method result in a bias between the original F1790-97 test
method and the revised F1790-05 test method when using the CPP. F1790-05 was not widely adopted
in North America because of this bias and large amount of data and experience accumulated with
F1790-97. F1790-97 continues to be the test method predominately practiced when using the CPP
device. To reduce confusion for end-users of F1790/F1790M and to allow for differences between
testing devices, the subcommittee has decided to limit the scope of F1790/F1790M to include only the
CPP device and create a separate test method for use of the TDM-100.

INTRODUCTION
Cut resistance is an important property for protective clothing and equipment, and several standard
testing devices have been adopted across different industries to measure this property. A common
practice in cut resistance testing is to subject a material specimen to a transversely moving blade under
an applied load and measure the distance of blade travel required to cut through the specimen. This
test method calculates the load required to cut through different specimens at 25.4 mm [1 in.] blade
travel. This calculated load, defined as a rating load, can be used to compare the cut resistance of
materials.
The original F1790-97 test method defined a commercially-available apparatus known as the Cut
Protection Performance Tester (CPP). In an attempt to harmonize F1790/F1790M with ISO 13996
(another international testing standards for measuring cut resistance) and improve the test method, the
scope of the test method was changed in F1790-05 to allow the use of other cut testing equipment,
specifically the Tomodynamometer (TDM-100) and a modification to the CPP arm called the Modified
CPP (mCPP). The revision addressed issues related to measurement of high frictional coefficient
materials like elastomers, specimen mounting, rating load calculation, and other procedures to
harmonize with ISO 13997:1999. After further round-robin evaluation by the subcommittee, it was
demonstrated that the revisions to the test method result in a bias between the original F1790-97 test
method and the revised F1790-05 test method when using the CPP. F1790-05 was not widely adopted
