  1. Adhesive Performance. The adhesive shall be an acrylic adhesive having the following minimum values:
  • Peel Strength (PSTC #1 at 70ºF and a 72 hour dwell)
    on Stainless Steel 80 ounces/inch of width
    on Polyester 70 ounces/inch of width
  • Shear Strength (PSTC #7 at 70ºF) 20 hours
  1. Weathering. The label shall be weathered using ASTM D4329 and UVA 340 lamps. After 5,000 hours of exposure in a QUV weathering deck the label shall remain adhered and readable. Sample of weathered and printed label shall remain on file at label manufacturer and is available for review by the customer.
  2. Chemical Resistance. The material shall have the following resistance to exposure:
     
    3. Chemical Rating
    Mild Acids Excellent
    Mild Alkalines & Salt excellent
    Water Excellent
    Solvents excellent

 

  1. Size. The labels shall have the following dimensions:


    2. 3/4" x 7-1/2"
    1-1/4" x 7-1/2"
    3-3/8" x 7-1/2"
    3" x 13-1/2"

  2. Ink Color & Printing. The legend and bar-code shall be printed in black on a white or yellow background. The printing shall be free of voids or striations.
  3. Bar-Code. The bar-code shall be printed using Code 128. All bar-codes shall have a rating of "A" using ANSI N10.8/M-1983. A copy of the bar-code verification and rating report shall be included with each order.
  4. Magnetic Backing Plate [optional]. To make certain labels removable and reusable, the label shall be attached to a magnetic backing plate. The magnetic plate shall be 1/8" longer and wider than its corresponding label. The plate shall have a thickness of 0.030" and have a magnetic pull of 72 lbs per square foot.
  5. Backslit. Labels not having a magnetic backing plate shall have a backslit liner so that the liner can be easily removed.
  6. Installation. The labels shall be applied to a clean, dry surface. Use a 3M Scotchbrite pad (or equivalent) to remove any surface oxidation, dirt or paint chalking from application surface and to rough up the surface. After this treatment the surface shall be cleaned with Surface Prep 77 or equal. Labels shall be applied at temperatures above 40ºF.
  7. Packaging. 25 labels shall be packaged in a polyethylene bag or vacuum formed package. The labels shall be packaged in sequential order. Bags or packages shall be packaged in a corrugated carton. The outside of each box shall be labeled with the bar-code legend sequence, the part number and/or utility code number, description and quantity.
  8. Warranty. Workmanship and quality shall be such that all lettering is sharp, legible, straight, and aligned properly. Smudges, misalignment, miss-wording, misspelling, crooked letters, incorrect color, incorrect materials, and any other problems that show poor quality and workmanship will give sufficient cause to reject any label. The products are to be guaranteed by the vendor to be free of workmanship or material defect. If, for reasons of workmanship or material defect, the label becomes unreadable during a period of five years, the vendor shall replace the label at no additional charge.
