1.5 DEFINITIONS
A. Certificate of Compliance (COC): An official document certified by an authorized
representative within the manufacturer's company that the manufactured
synthetic turf reinforcement mat product(s) meet designated property values as
manufactured in a facility having achieved ISO 9001:2015 certification and tested
in accordance with GAI-LAP procedures.
B. High Performance Turf Reinforcement Mat (HPTRM): A long-term, non-
degradable RECP composed of ultraviolet (UV) stabilized, non-degradable,
synthetic fibers, nettings and/or filaments processed into three-dimensional
reinforcement matrices designed for immediate and permanent protection for
erosion control applications where design flows exert velocities and shear
stresses that exceed the limits of mature natural vegetation. The HPTRM MARV
tensile strength per ASTM D-6818 is 3000 lbs/ft in the weakest principal direction.

C. Manufacturer: Entity that produces synthetic HPTRM products through a process
directly utilizing obtained raw materials, in a facility owned and operated by said
entity, using equipment and assemblies owned and operated by said entity,
subject to a certified Manufacturing Quality Control (MQC) Program. Upon
completion of production, the manufacturer may sell the HPTRM product(s)
directly to the customer, or through a vendor entity.
D. Manufacturing Quality Control (MQC) Program: A certified and documented
program initiated and operated by the manufacturer that outlines the operational
techniques and activities which sustain a quality of the synthetic HPTRM
product(s) that will satisfy given needs.
E. Minimum Average Roll Value (MARV): Property value calculated as typical minus
two standard deviations. Statistically, it yields a 97.7 percent degree of
confidence that any sample taken during quality assurance testing will exceed
value reported.
F. Rolled Erosion Control Product (RECP): A temporary degradable or long-term
non-degradable material manufactured or fabricated into rolls designed to protect
the soil surface, reduce soil erosion and if needed assist in the growth,
establishment and protection of vegetation.
G. Securing Pin: A device designed to secure the HPTRM in place during
installation, or until the establishment of vegetation occurs.
H. Trilobal Monofilament Yarn: A multi-dimensional polymer fiber with at least three
points, providing increased surface area and grooves/channels along the fiber to
capture additional moisture and sediment to enhance vegetative growth.
I. Typical Roll Value: Property value calculated from average or mean obtained
from test data.
J. Vendor: An entity that provides high performance turf reinforcement mat
product(s) to a customer, on behalf of an independent manufacturer. A vendor
does not manufacture the actual engineered earth armoring solution product(s)
and is not subject to certified MQC Program provisions.
