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-477 is RoHS compliant to 2005/618/EC MCV amendment to RoHS Directive 2002/95/EC.

SPECIAL FEATURES
B-477 has a static dissipative adhesive and is supplied on a static dissipative release liner. It has surface resistivity values in the recommended range for Dissipative ESD Packaging Materials as defined in Table 1 of ANSI/ESD S20.20 (³ 1x10⁵ to < 1x10¹² ohms). B-477 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-477 in combination with the Series R6000 and Series R6000HF ribbons passes the requirements of MIL-STD-202G, Notice 12, Method 215K.
