Brady B-499A: Thermal Transfer / Dot Matrix Printable Nylon Cloth Label

B-499A is a polyamide coated nylon cloth label with a permanent acrylic adhesive, printable with thermal transfer or dot matrix ribbons, intended for wiremarking and general labeling. The sheet states plainly that B-499A is not recommended for outdoor use, and a footnote on the weatherability row adds that it is not recommended for long-term outdoor use — after 30 days in a Xenon Arc Weatherometer the material wrinkled and embrittled. UL recognition and CSA acceptance apply only when the label is printed with specific named ribbons, so the ribbon a customer uses determines whether the approval applies.

Extracted directly from Brady Technical Data Sheets to prevent real-world application failures and chemical degradation:

• Outdoor use, stated under the APPLICATIONS heading: "B-499A is not recommended for outdoor use."
• Footnote to the performance properties table. The row label reads "Weatherability*" and the matching note sits directly below the table: "*B-499A is not recommended for long-term outdoor use." The asterisk ties this note to the weatherability row specifically.
• Weatherability result belongs to the weatherability row only: after ASTM G155, Cycle 1, 30 days in a Xenon Arc Weatherometer, "Material wrinkled and embrittled."
• UL: "B-499A is a UL Recognized Component to UL969 Labelling and Marking Standard when printed with Brady Series R4300, R4900, R6000 Halogen Free thermal transfer ribbons and Brady Series R5000 dot matrix ribbon. See UL file MH17154 for specific details." UL information can be accessed online at UL.com, searching in the Certifications area. The recognition is conditioned on those named ribbons.
• CSA: "B-499A is CSA Accepted to C22.2 No.0.15-95 Adhesive Labels Standard when printed with Brady Series R4300 thermal transfer ribbon. See CSA file 041833 for specific details." CSA information can be accessed online at https://www.csagroup.org/testing-certification/product-listing/ The acceptance is conditioned on the R4300 ribbon alone; no other ribbon is named in the CSA statement.
• Ribbon scope, stated as an observation about which ribbons each statement names rather than as a verdict on any ribbon. The Recommended Ribbons list includes R4300, R4900, R6000 Halogen Free, R6200 and R4500 colored (red, blue and green) thermal transfer ribbons plus the R5000 dot matrix ribbon. The UL statement names R4300, R4900, R6000 Halogen Free and R5000; it does not name R6200 or R4500 colored. The CSA statement names only R4300. The performance and chemical resistance testing covers R4300, R4900, R6000 Halogen Free, R6200 and R5000; R4500 colored appears only in the Recommended Ribbons list and in no test or approval statement on the sheet.
• Weee-RoHS: the sheet does not state a compliance status. It says only, "For information on the Weee-RoHS compliance status for a Brady Product go to one of the following websites:" In Canada www.bradycanada.ca/weee-rohs; In Europe www.bradyeurope.com/rohs; In Japan www.brady.co.jp/products/labelsuse/rohs; All other regions www.bradyid.com/weee-rohs
• DIN VDE 0472 Part 815, listed under SPECIAL FEATURES: "Brady B-499A meets requirements of a halogen-free material per DIN VDE 0472 part 815. (Statement based on review of product construction and confirmation halogen content test run at an independent test laboratory)"
• Storage limit tied to shelf life: shelf life is two years from the date of receipt only while stored in its original packaging in an environment below 80° F (27° C) and 60% RH. The sheet adds, "It remains the responsibility of the user to assess the risk of using this product. We encourage customers to develop testing protocols that will qualify a product's fitness for use in their actual applications."
• Sheet-wide disclaimer printed after the trademarks list, scope not tied to any single row: "Note: All values shown are averages and should not be used for specification purposes." It continues, "Test data and test results contained in this document are for general information only and shall not be relied upon by Brady customers for designs and specifications, or be relied on as meeting specified performance criteria. Customers desiring to develop specifications or performance criteria for specific product applications should contact Brady for further information."
• Basis of compliance information, printed alongside the disclaimer above: "Product compliance information is based upon information provided by suppliers of the raw materials used by Brady to manufacture this product or based on results of testing using recognized analytical methods performed by a third party, independent laboratory. As such, Brady makes no independent representations or warranties, express or implied, and assumes no liability in connection with the use of this information."
• Unit derivation note: "All S.I. Units (metric) are mathematically derived from the U.S. Conventional Units."
