Installer or Contractor Qualifications
1.  Installations will be performed by skilled tradesman experienced and trained in the flooring modifications and alterations.
1.3 Reference Standards 
A. Manufacturer provides each ramp in accordance with the model descriptions and specifications established herein.  All ramps shall be installed in accordance with all governing agencies with jurisdiction and in accordance with the Americans with Disabilities Act (ADA, 1990) and local and state access codes.
EZEdge™ Transition Ramp products shall be in compliance with the ADA and Accessibility Guidelines (ADAAG) Sections 4.2.5 (Changes in Level) and 4.8.2 (Slope & Rise) of the Federal Register, 28 CFR, Part 36 and ANSI Standard A117.1. (1992), CABO and California Title 24, unless otherwise specified by the customer. All SafePath Ramps and Reducers shall NOT exceed 7.5% maximum slope requirement(exception MREZ 2190-2195 & MRED 21900, which has shims affixed to the bottom of the transition). 
All EZ Edge™ Ramp products shall have side and back bevel cuts via a CNC cutting system. This process shall provide each side and back of the product with a back-bevel of 8 degrees or 14.05% or less. This beveling is essential for butting to existing vertical substrates and connecting products in a contiguous manner for vertical runs.

1.4 Performance 
A.  EZEdge™ Transition Ramp products meet or exceed the following tests:
ASTM D 412 Tensile Elasticity 630psi
ASTM D395-82 Comp. Test 7.84%
ASTM D 2240 Hardness 65 (Shore A)
ASTM C 1026-84H20 Absorb. .75%
Density 1.01 grams/cm³ 
1)  EZEdge™ Transition Ramp
products have no load weight limitations when properly installed according to manufacturer instructions.  
B.  EZEdge™ Transition Ramps exceeded all recognized standards utilizing three test methodologies for Static Coefficient of Friction (SCOF), Fixed-Angle Ramp-Walking, and Surface Roughness.
1)  Static Coefficient of Friction (SCOF)
ASTM C 1028-96  (Dry- 0.95)
ASTM C 1028-96  (Wet- 0.79)
Static Coefficient of Friction values of 0.60 or higher are considered adequate for level floors in normal pedestrian traffic in commercial areas.  Sliders used in testing were of Neolite synthetic rubber.  Other materials used for SCOF included:
     ASTM C 1028-96 Dry Leather (0.79)
  ASTM C 1028-96 Wet -4 S rubber (0.82)
  ASTM C 1028-96 Wet TRL rubber (0.95)
ASTM F609 Rubber 0.80
    2)  Fixed Angle Walking
Utilizing two test subjects, one male and one female, facing a down slope and an up slope at a flooring angle of 27 degrees with wet running water.  Angle of degree corresponded to a SCOF of 0.50.  Under normal walking conditions a SCOF of 0.40 (22 degrees) is a widely accepted minimum for walking tests of flooring for level surfaces.  Testing angle appreciably exceeds the minimum safety criterion.

2.3 Coating Materials 

SafePath™ Products’ ERC Color Coating™) coating system:  
This invention requires an application of a base adhesive base coat (Aromatic Polyurethane) Part A mixed at unequal amounts with A Part B (Polyol) then applied using a roller or spray machine. At a precise time during this operation of application the top colorant coat is applied using a roller or spray machine using a water-based colorized aliphatic polyurethane. 

SafePath™ Products’ ERC (Elegant Rubber Coating™ coating system:
1.  Coating system is a two-component, rapid-curing, hand-applied, non-solvent no VOC protective color coating that is delivered ready to use.  The two-part coating process is performed by the manufacturer SafePath Products™. All coating materials used are all ZERO VOC utilizing Waterborne 
Polyurethane Dispersion and two-part base coat as the binder.  
2.  ERC (Elegant Rubber Coating™) is a patent pending formula that has expansive elongation of over 25%. 
3. Abrasion wheel testing. These specimens were abrasion tested according to section 8.6 in ASTM Fl344 "Standard Specification for Rubber Floor Tile" (referencing ASTM D338 9). No SCOF rating has been performed on the ERC products, however a non-slip additive may be added upon request to provide a greater SCOF rating for the ERC product line.

Part 3 Execution
Ramps shall be installed in accordance with manufacturer’s instructions using ONLY recommended non-corrosive silicone adhesive sealants or mechanical fasteners. 

3.1 Preparation
A.  Surfaces must be dry, clean, and free from dirt, oil, frost, and all other foreign materials, and have a minimum surface temperature of 35°F (3°C).  EZEdge™ Transition Ramps can be applied over expansion joints up to ½” (12mm) in width.  In accordance with manufacturer’s guidelines, fill holes and cracks greater than ½” (12mm) in depth.  Remove all bumps and foreign surfaces.  Abrade highly polished and waxed surfaces.
B.  Field verify all dimensions for vertical heights and path widths.  Cut and modify ramps to meet specific installation requirements.  Ramp’s underside may be beveled, planed, or ground to accommodate minor inconsistencies in existing level surfaces.
C.  Fit Ramp for size and application and then apply adhesive using heavy-duty hand or air dispensing gun and spread evenly with a notched trowel on the underside of ramp.  Wait 5 minutes but no more than 15 minutes before applying ramp to substratum.  Adhesive cures in 24 hours; foot traffic is permitted after 4 hours.

Warranty
SafePath™ Products and Van Duerr Industries, Inc. warrants that EZEdge™ Transition Ramp products will be free of any defect of material or workmanship for a period of (10) ten years from date of purchase.  Coated surfaces are warranted against fading and peeling, and delaminating in interior applications for (1) one year from the date of purchase.
