Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
EMI/RFI Shielding Tapes
When using these tapes galvanic compatibility should be taken into account.
3M™ Copper Foil Shielding Tape 1181
3M™ 1181 Tape consists of a 1-ounce deadsoft copper foil backing and a unique electrically conductive pressure-sensitive acrylic adhesive.
Features and Benefits
• Copper foil with conductive acrylic adhesive
• Deadsoft 1-ounce copper foil backing
• Supplied on a removable liner for easy handling and diecutting
• The copper foil backing is solderable and resists oxidation and discoloration
• Common uses include grounding and EMI shielding in equipment, components, shielded rooms, etc.
Benefits of choosing 3M Aluminium Foil Tape
• Extreme Hot and cold temperature versatility. 3M foil tape works in temperatures to which other tapes would diminish. Performing in cold conditions allows this 3M tape to be a market leader, as other tapes see the adhesive harden and begin to lose sticking strength. On the contrary, extreme heat can melt adhesives of tapes, but not the 3M foil tape making it versatile for most applications.
• An Acrylic Adhesive backing. This 3M Aluminium foil tape is coated in a superior acrylic adhesive, which works well in extreme cold and heat conditions. This matters when comparing to most duct tapes that are made with a rubber adhesive. This is then known to delaminate from its backing in these extreme conditions. Other adhesives can offer greater resistance but will lack mechanical strength, poor ageing resistance and UV light.
• Longevity of foil tape. Within the construction industry, the use of pressure sensitive tapes is often used in hard to reach areas. This means they can't be easily replaced or repaired. The acrylic adhesive on the 3M aluminium foil tape offers better cohesion, adhesion and thermal properties.
