Progressive Engineering Evaluation Service is an accredited ISO Standard 17065 Product Certifier.
Recently, PEI tested and certified Marino\WARE's Viper20 Stud as meeting the requirements of ASTM C1629 for Soft Body Impact Resistance.
Currently, sellers advertise high-impact wallboards as achieving Level 3 Impact Resistance with 30 mil studs. Now Viper20 has also achieved Level 3 impact resistance with seven high-impact wallboards. PEI compiled this data into an Assembly Evaluation Report, the full text of which is available here.
Marino\WARE stands behind their Viper20 product with high-impact wallboards, and have the third party documentation to back it up.
