The International Geosynthetics Society North American Chapter (IGS North America) will host a webinar on December 19: Understanding the Role of Minimum Average Roll Values (MARV) in Geosynthetic Specifications. Beth Wilbanks (TenCate Geosynthetics) will lead the 1:00 – 2:00 pm EST session.

Non-members: USD $20
MARV & GEOSYNTHETIC SPECIFICATIONS
In announcing the webinar, IGS North America writes:
An understanding of minimum average roll value is essential to ensure that data support product requirements reported by the manufacturer. There appears to be confusion in the geosynthetic industry concerning the application and definition of product requirements, particularly as they relate to MARV. MARV is a statistical value and not a ‘minimum’ number. The interpretation of these values has become an issue and actual data may not support a calculated MARV that meets or exceeds the published MARV.
The webinar will help sort through this confusion and pass along key understanding:
- The statistical approach used to determine MARV
- Current methods of calculation for MARV as compared to the statistical approach based on process performance
- Additional guidance including ASTM test methods will be discussed to provide an organized approach to sampling, testing and management of test data and certifications
Participants will earn 1 PDH at the conclusion of this webinar.
