Abrasion resistance is estimated by a lab test in which the material is rubbed back and forth on an abrasive surface.The number of cycles the material withstands before a hole forms determines its abrasion resistance rating. Tear strength is
measured in pounds of force necessary to tear the material. Like TPP ratings, real world results will vary depending on a variety of factors, such as:

Materials and Protection:
We make both SFI 3.2A/1 and 3.2A/5 rated suits. 3.2A/1 suits are made with one layer of fire retardant material, 3.2A/5 rated suits consist of two or three layers of material in different combinations. Most importantly, a multi-layer suit provides
three to four times as much protection as a single layer suit based on SFI certified

Thermal Protective Performance (TPP) testing.
