In industrial applications, steel surfaces are routinely coated to shield against corrosion. To prepare these metal surfaces for painting, they undergo cleaning and texturing, often accomplished through grit, or shot blasting. Striking the right balance is crucial; a surface that is too smooth won't retain the paint, while excessive roughness might cause rusting by allowing peaks to penetrate the coating. This is where the Testex Replica Tape comes in. Testex Replica Tape gauges surface profiles by generating a duplicate of the surface, enabling measurement with a micrometer. This method provides accurate data about surface roughness and texture, ensuring compliance with quality standards in various industrial applications. Advantages of this method: Simple technique: place on the surface, press/burnish it into the surface, remove, and measure Proven technique with accuracy and repeatability validated by numerous independent studies Measure using an analog precision micrometer or electronic PosiTector RTR H Replica Tape Reader Less than 30 seconds required per test Only surface profile measurement method recognized by ISO, ASTM, and AMPP Conforms to ASME B46, ASTM D4417, ISO 8503-5, NACE SP287, SSPC-PA 17, SP5, SP6, SP10, SP11-87T, and others The Testex Press O Film Replica Tape consists of a layer of compressible foam affixed to an incompressible polyester substrate of highly uniform thickness. When pressed against a roughened steel surface, the foam collapses and forms an impression of the surface. Placing the compressed Testex tape between the anvils of a micrometric thickness gage such as the PosiTector RTR H Replica Tape Reader and subtracting the contribution of the incompressible substrate gives a measure of the surface profile Optical Grade XC Testex Replica Tape are also available. This tape provides higher quality SDF surface data files than conventional replica tape. It is to be used with the PosiTector RTR 3D models. Each roll of Testex Tape includes 50 pieces of Impressions. How It Works? Step 1 Prepare the surface prior to application. Let's ensure surface cleanliness by using putty to eliminate dust and other impurities. Utilize cleaning putty to eliminate dust, debris, or any remaining blast media from the measurement site. Gently press the putty onto the test surface with your fingers, then remove it to achieve a clean surface. Step 2 Choose the suitable grade of replica tape, then peel a single piece from its release paper and affix it to the blasted surface. Next, firmly press the replica film onto the surface using a burnishing tool, applying ample pressure in a circular and horizontal rubbing motion. Once done, detach the tape from the surface. Step 3 Place the compressed replica tape between the measurement anvils of the micrometer and record a measurement. Verify that the tape is correctly oriented, with the burnished area centered between the anvils and the adhesive side facing downward. This is an illustration of the tape surface of the entire process.

TECHNICAL SPECIFICATION
Conventional Testex Press-O-Film Tape Grades
Testex Press-O-Film replica tape is available in a variety of thickness ranges for measuring substrate roughness. The primary range for measurement with replica tape is 20 to 115 µm (0.8 to 4.5 mils). Use of Coarse Minus grade (<20 µm or <0.8 mil) or X-Coarse Plus grade tape (>115 µm or >4.5 mils) should primarily be restricted to checking measurements at the lower and upper ends of the primary range.
| Order Code | Grade | Range | Measurement Tool |
| RTCMIN | Coarse Minus | 0.5 to 1.0 mils | 12 to 25 µm | Testex Micrometer or PosiTector RTR H |
| RTC | Coarse | 0.8 to 2.5 mils | 20 to 64 µm | |
| RTXC | X-Coarse | 1.5 to 4.5 mils | 38 to 115 µm | |
| RTXCPLUS | X-Coarse Plus | 4.6 to 5.0 mils | 116 to 127 µm |
Optical Grade Testex Press-O-Film Tape Grades
Testex Press-O-Film Optical Grade replica tape, when used with PosiTector RTR 3D models, provides higher quality surface data files (.SDF) than conventional replica tape. Optical Grade Replica Tape is available in Coarse or X-Coarse.
| Order Code | Grade | Range | Measurement Tool |
| RTCOG | Optical Grade Coarse | 0.8 to 2.5 mils | 20 to 64 µm | PosiTector RTR 3D |
| RTXCOG | Optical Grade X-Coarse | 1.5 to 4.5 mils | 38 to 115 µm |
