Where the specs differ
Products in the same weight class are not automatically interchangeable. Check the property your specification actually names. Filtration work turns on apparent opening size and permittivity; separation and stabilization under aggregate turn on grab tensile and CBR puncture. Two fabrics at the same nominal weight can differ on any of them.

| Grab tensile strength | ASTM D4632 | 425 MD / 350 CD lbs |
| Grab tensile elongation | ASTM D4632 | 20 MD / 20 CD % |
| Trapezoid tear strength | ASTM D4533 | 145 MD / 125 CD lbs |
| CBR puncture strength | ASTM D6241 | 1340 lbs |
| Apparent opening size (AOS) | ASTM D4751 | 40 U.S. sieve (0.425 mm) |
| Permittivity | ASTM D4491 | 0.96 sec⁻¹ |
| Flow rate | ASTM D4491 | 70 gal/min/ft² |
| UV resistance at 500 hours | ASTM D4355 | 90 % strength retained |
