estex Replica Tape
for Measuring Surface Profile
Testex Replica Tape measures surface profile by creating a replica of the surface, which can be measured using a micrometer
- 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 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

Press-O-Film Replica Tape
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 micrometer thickness gage and subtracting the thickness of the incompressible substrate gives a measure of the surface profile.
Each roll of Testex Tape includes 50 pieces (impressions).
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.
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 |
| E122-A | Coarse Minus | 0.5 to 1.0 mils 12 to 25 µm |
| E122-B / E122-BO | Coarse | 0.8 to 2.5 mils 20 to 64 µm |
| E122-C / E122-CO | X-Coarse | 1.5 to 4.5 mils 38 to 115 µm |
| E122-D | X-Coarse Plus | 4.6 to 5.0 mils 116 to 127 µm |
