Environmental Compliance

AllꢀKEMETꢀFlameꢀSensorsꢀareꢀRoHSꢀandꢀREACHꢀCompliant.

Article 33(1) of the REACH Regulation states that manufacturers and importers of articles (products) are required to notify

their customers of the presence of any Substances of Very High Concern (SVHC) in their products exceeding 0.1% by weight

and provide instructions on safe use of the product.

KEMET Corporation reports regarding the Article 33(1) of REACH Regulation as follows:

1. Applicable Product: Flame Sensors (QFC, QFCE, QFS & QFSM series)

2. Report for the content of REACH SVHC list:

The product(s) above contains a substance by more than 0.1wt% per product weight that was published in the 8th update of

the REACH SVHC substances (December 19, 2012).

3. Regarding the safety of the ﬂame sensors (Piezoceramic products):

The Piezoceramic that is used in this product becomes ceramic by sintering powder containing PZT as the main ingredient. It

is chemically stable, with minimum risks toward the human body or environment within the intended use of the product. Please

note that risks could occur in the case of inhalation or accidental oral uptake of powder ceramics.

4. Technical product information on the ﬂame sensors (Piezoceramic products):

The manufacturing technique of the “piezoceramic products” whose main ingredient is Lead Titanium Zirconium Oxide (PZT)

has been established, and there is no alternative material that can exhibit superior performance than PZT at this moment.

Please note that the piezoceramic is listed as an exempt on RoHS (2011/65/EU) AnnexIII (7c.1).

5. The responsibility of piezoceramic manufacturers:

Piezoceramic manufacturers report information regarding PZT containment in their products to the customers to obey the

article 33 of the REACH regulation
