Thickness Measurement Location (TML)

Ultrasonic Testing (UT) Labels

Specifications:

NDT Inspection LabelsNDT Inspection Point Labels are used across a number of Processing & Refining Industries, maintaining these following specifications:

  • Constructed of 3.5 mil matte silver mylar polyester material with a 1.0 mil UV laminate. The matte coating resists degradation from scuffing, chemicals, moisture and wide temperature fluctuations.

  • The adhesive is a high-performance acrylic for excellent bonding to metals, HSE plastics and a wide variety of painted & textured surfaces.

  • Low-leachable chloride, fluoride and sulfur in the adhesive.

  • Typical values for continuous temperature resistance range between -40°F (-40°C) and 300°F (149°C). The minimum application temperature is 58°F.

    		 Label TML-D:

  • Measures 1”x 2” with a .75” diameter opening for inspection and a blank space for on-site inscription.

  • A 1.0 mil environmental protectant laminate is included as an integral part of the label with a removable tab to overlay the inscribed marking.

  • The standard label is bright orange.

  • Wording: “DO NOT REMOVE, NDT PT”

    		 Label TML-H:

  • Measures 1.5”x 1.5” with a .625” diameter opening and a blank space for on-site inscription.

  • A 1.0 mil environmental protectant laminate is supplied as an integral part of the label with a removable tab to overlay the inscribed marking.

  • The standard label is bright green.

  • Wording: “DO NOT PAINT, NDT POINT”

    • NDT Inspection LabelsFor installation of the NDT Inspection Point Labels, installers should:

  • Be sure application surface is at room temperature or slightly higher. The minimum application temperature for the adhesive is 58°F (15°C).

  • Clean and dry the application surface for maximum bond strength. The surface should also be free of loose particulate, such as dust, dirt and corrosion. A typical cleaning solvent is heptane or an industrial grade isopropyl alcohol. (Consult the manufacturer’s Material Safety Data Sheet for proper handling and storage of solvents.)

  • Note: Acrylic adhesive requires 48-72 hours to achieve 90% of its ultimate bond strength. Several weeks are required to achieve 100% of ultimate bond strength. Higher initial bonds are achieved through increased rub down pressure.
