244 Cut resistance: Comparison between EN 388-2016 and ANSI/ISEA 105-2016 ANSI/ISEA&EN388 cut test standards Newtons 2016 EN 388 2016 ANSI/ISEA Weight (G) needed to cut with 1” (20mm) blade travel Level A1 > 200 G > 500G > 1000G > 1500 G > 2200 G > 3000 G > 4000 G > 5000 G > 6000 G A2 A3 A4 A5 A6 A7 A8 A9 Low cut High cut When comparing the cut resistance of two or more fabrics, it is important to make sure that for all materials: • The same test method was used • The same type of cut tester was used Unless these points are met, you cannot accurately compare the results. Cut resistance levels: The use of the TDM-100 test method is required by both ANSI/ISEA 105 and by EN 388 (for high-cut materials). However, the ANSI/ISEA standard reports results in grams on an A1-A9 scale (2006000 grams/2-60 Newtons). While the A1-A9 scale is comparable to the EN 388 A-F levels which reports up to 30 Newtons (200-3000 grams/2-30 Newtons), ANSI/ISEA extends their scale by three levels to 6000 grams/60 Newtons to report high cut materials more accurately. Puncture & Needle Testing Explained The ANSI/ISEA 105 Test In February of 2016, the ANSI/ISEA 105 standard was updated and published to include two puncture standards: Puncture Resistance (other than hypodermic needle) and Hypodermic Needlestick Puncture. Prior to 2015, there was only one puncture test, which did not specify the type of puncture hazard the standard was created for, leaving it open for interpretation. Having both an industrial puncture standard and a hypodermic needle puncture standard allows safety managers to differentiate between what protection they need most, based on more relevant testing and classification. EN 388: Industrial Puncture Resistance (Non-Hypodermic Needlestick Puncture) The EN 388 probe is the approved puncture test for ANSI/ISEA 105 and measures the amount of force needed for a blunt probe to pierce through the sample material (taken from palm). • The blunt probe moves at a 90˚ angle at a speed of 100mm/minute • Results are reported in Newtons and are given a 1-5 classification rating, with 1 being low resistance and 5 being high resistance • The test is done 4 times for every palm sample • The lowest score is reported ASTM F2878: Hypodermic Needlestick Puncture Resistance The ASTM F2878 is the approved puncture test for ANSI/ISEA 105 and measures the amount of force needed for a 25-gauge hypodermic needle to pierce through the sample material. • The puncture probe (25-gauge needle) travels at a 90˚ angle into specimen at a vector of 500 millimeters per minute. • Results are reported in Newtons and are giving a 1-5 classification rating, with 1 being low resistance and 5 being high resistance • The test is done 12 times for every palm sample • The average of the 12 results is reported ANSI/ISEA 105 Industrial Puncture Resistance ASTM F2878 Hypodermic Needlestick Puncture Resistance 70 A1 A2 A3 A4 A5 A6 A7 A8 A9 30 40 50 60 10 20 0 F D E A B C
