ČSN EN 16738 This European standard specifies a test method for the determination of emissions resulting from the use of combustible air fresheners into indoor air by means of chamber operation according to EN ISO 16000 9. This standard defines specific testing conditions for the measurement of the emissions from combustible air fresheners which minimize the effect of the testing on the combustion process. This standard provides a measurement method for the determination of the following non-exhaustive list of target substances emitted directly from the burning process: - VOC; - Benzene; - Naphthalene; - Formaldehyde. The measurement method can allow the determination of other substances. This standard provides additional information on the optional measurement of the following substances: - SO2; - NOx; - CO. This standard is not suitable for the quantitative determination of particulate matter. This standard does not apply to non-combustible air fresheners and loose incenses. Any scented candle with burning time shorter than 2,5 h is outside the scope of the standard.

ČSN EN 16654 This European Standard specifies requirements and test methods for consumer fitted finger protection devices intended to be mounted on hinged doors in the domestic environment inside buildings in order to prevent crushing injuries to children as a result of the door closing. A finger protection product is based on at least one of three protection methods: hazard shielding, shut prevention or shut controlling. NOTE 1: Products intended to maintain the door in a fixed position and friction hinges are not covered by this European Standard. NOTE 2: Finger protection devices intended to be installed by professionals or that are an integral part of the door system are beyond the scope of this European Standard.
