SP Provning Forskning: ESD-approved for IEC 61340-5-1 and EN 100015-1 per SP Swedish National Testing and Research Institute (see ESD-approval DNo: 230-01-0169)

Brady B-478 is RoHS compliant to 2005/618/EC MCV amendment to RoHS Directive 2002/95/EC.

SPECIAL FEATURES
B-478 has a static dissipative adhesive and is supplied on a static dissipative release liner. It has surface resistance values in the recommended range for Dissipative ESD Packaging Materials as defined in ANSI/ESD S541-2003 (³ 1x10⁴ to < 1x10¹¹ ohms).

B-478 also meets the requirements of EIA-541 "Packaging Material Standards for ESD Sensitive Items" in which a charged material must decay to 1% of its initial voltage in less than 2 seconds.

B-478 has a low profile (1 mil) film, allowing for easier use in processes which demand thin and/or lighter weight label materials.

B-478 in combination with the Series R6000 and Series R6000HF ribbon passes the requirements of MIL-STD-202G, Notice 12, Method 215K.

B-478 meets the requirements of a halogen-free material per DIN VDE 0472 part 815. (Statement based on review of product construction and confirmatory halogen content test run at an independent test laboratory.)
