Rating and serial plates that require high performance and evidence of label removal.

RECOMMENDED RIBBONS
Brady series R6000 and R4400 colored (red, blue, and green)

REGULATORY/AGENCY APPROVALS
UL: B-7546 is UL Recognized to UL969 Labeling and Marking Standard when printed with Brady series R6000 ribbon. See UL file MH17154 for specific details. UL information can be accessed online at ul. com. Search in Certifications area.
CSA: B-7546 is CSA Accepted to C22.2 No. 0.15-95 Adhesive Labels Standard when printed with the Brady series R6000 ribbon. B-7546 is approved to Type C (tamper evident). See CSA file 041833 for specific details. CSA information can be accessed online at directories.csa-international.org.

RoHS: Brady B-7546 is RoHS compliant to 2005/618/EC MCV amendment to RoHS Directive 2002/95/EC.



SPECIAL FEATURES
B-7546 is designed to leave a "VOID" footprint when the label is removed. In addition, a "VOID" pattern will appear on the top surface of the label in order to prevent it from being reused. Recommended 24 hour room temperature dwell before removal for full tamper evident performance. The adhesive nature of this product does not allow for repositioning and requires minimal handling in order to prevent prematurely exposed VOID pattern.

Tamper evident adhesive performance properties were tested on B-7546 laminated to the indicated surfaces, exposed to the indicated environments and removed from the environments prior tp testing. The label was removed at a 135° angle with a peel rate of 90 in/min and the remaining VOID adhesive pattern on each surface was observed.

Performance properties tested on B-7546 samples printed using Series R6000 ribbon and a BradyPrinter™ THT Model 300X Thermal Transfer Printer. The labels were printed with alphanumerics and 3:1 ratio with 6 mil minimum X dimension barcode. Printed samples of B-7546 were laminated to aluminum before exposure to the indicated environmental condition.

Some loss of tamper evidence.

The tamper evident VOID pattern of B-7546 was retained after exposure to all of the listed conditions except for weatherometer.

* Laboratory testing has shown that the tamper-evidency VOID pattern of this product may become nonfunctional after exposure to temperatures higher than 80°C.


PERFORMANCE PROPERTY
CHEMICAL RESISTANCE

Samples printed with a BradyPrinter™ THT Model 300X using Brady Series R6000 ribbon and then laminated to aluminum panels. Test was conducted at room temperature after 24 hour dwell. Testing consisted of 5 cycles of 10 minute immersions in the specified chemical reagent followed by 30 minute recovery periods. After final immersion, samples rubbed 10 times with cotton swab saturated with test fluid.
