ANSI/ISEA 105
This is the standard that assigns “levels” according to the gram weight from ASTM Testing and utilizes the ASTM F2992-15 standard.

Cut Level A1 ≥200 to 488 grams
Cut Level A2 ≥500 to 999 grams
Cut Level A3 ≥1000 to 1499 grams
Cut Level A4 ≥1500 to 2199 grams
Cut Level A5 ≥2200 to 2999 grams
Cut Level A6 ≥3000 to 3999 grams
Cut Level A7 ≥4000 to 4999 grams
Cut Level A8 ≥5000 to 5999 grams
Cut Level A9 ≥6000 grams

Most common referred standard for ANSI Cut Level.

ASTM-F1790-97 -
This standard used the CPPT machine to measure cut resistance of fabric. This was the first standardized test method used to measure the load in grams that a textile material could withstand. Cut length in material is 25mm (approx. 1 inch). Uses a 4 inch blade that is only in contact with the material one time.

Advantages: Provided a working system to compare cut-resistant products.

Disadvantages: Microscopic sharpness of blades vary and need calibration. This causes variance from lab to lab (27% average).

CPPT - Cut Protection Performance Test. This test incorporated the ASTM 1790-97 method.


ASTM F1790-05 -
Updated version of the “97” test method. The cut length in the fabric was reduced to 20mm (approx. 3/4 inch). Also uses a 4” blade that only contacts the material one time.

Advantages: Provided a working system to compare cut-resistant products.

Disadvantages: Microscopic sharpness of blades vary and need calibration. This causes variance from lab to lab (27% average).

TDM-100 - Updated version of the CPPT machine. This machine changed the position of the fabric placement and the weight system.


ASTM F2992-15 -
Updated version of the ASTM F1790-05 test method published on July 1st, 2015. The cut length in the fabric stayed the same at 20mm (approx. 3/4 inch). The main change was this test now ranges from cut levels A1 to A9, instead of 1 to 5. This scale allows for testing higher cut resistant materials and to more accurately categorize them for results up to 6000 grams. The old scale peaked at 3500 grams for ANSI cut level 5. This test also requires that the TDM-100 machine is used with a new blade for each cut to ensure a more accurate result.

Advantages: More accurate cut level categories and a consistent cut testing machine.


EN 388 -
Used in the European Community Community. A series of tests to measure mechanical performance. This test method measures Abrasion, Cut, Tear, and Puncture. Remember ACTP!

This is a Coup Text machine. Much smaller and has a circular blade that spins and is pulled across the fabric under a constant weight of 500 grams. The number of cycles are recorded to cut the fabric.

Cut Resistant Cycles EN388

Level 0

Level 1

Level 2

Level 3

Level 4

Level 5

<1.2

>1.2

>2.5

>5.0

>10.0

>20.0

Advantages: EN 388 measures a variety of mechanical risks (ACTP).

Disadvantages: Intense concern and realization that once the blade cycles over the material the blade gets duller with each passing rotation. Inability to measure more cut-resistant engineered yarns containing steel wire. EU is in the process of abandoning this test procedure.
