A Technical Guidance Manual:
Terminology and Index Testing Procedures for Rolled Erosion Control Products

2. FOREWORD

During 1994 and 1995 the Erosion Control Technology Council (ECTC) sponsored an experimental program establishing standardized applications of various index test methods used to characterize rolled erosion control products (RECPs). In addition, an effort to establish consensus-based terminology was undertaken. This guidance manual is the result of these efforts and provides terminology and index testing guidance for both degradable and nondegradable RECPs.

It should be emphasized that the test instructions within this document are not a replacement to the governing test standard, but should be used in concert with the standard to assist the user in generating valid and repeatable test results. Where specific test standards are not available, sufficient detail is provided to assist the user in the performance of a test and/or test result determination.

Currently, ECTC is in the process of developing new test methods designed to better serve the erosion control industry. These tests are nearing completion and should be available during year 2002.
