Plastic Testing on the E-bike

DEKRA Expert Tip

In addition to the safety-related testing, the health aspects are also focused on in the testing of bicycles, e-bikes, scooters, and their varieties. Of particular interest here is the interface between human and vehicle, i.e. all components made of plastic or rubber with which the user comes into contact for a longer period.

To this end, at its accredited Laboratory for Environmental and Product Analysis in Stuttgart, DEKRA inspects the chemical safety of saddles or handles as well as their primary materials.

material testing

This can take place during product development, which can sometimes spare the manufacturers expensive subsequent product modifications.

The threshold values for the pollutant load are regulated in various ordinances and directives, such as REACH. According to these, plastic parts may contain only a certain quantity of polycyclic aromatic hydrocarbons (PAH). Products may not be circulated for the public if one of their components – which, in the case of normal or reasonably foreseeable use, comes into contact with human skin directly, for a longer period or repeatedly for a short time – emits more than 1.0 mg/kg of one of the PAH classified as cancer-inducing. Particularly in the case of cycling for longer periods, there is a risk of the passage of PAH due to sweat, temperature and contact duration.

If the threshold values for materials pursuant to AfPS GS 2014: 01 and pursuant to REACH RN (EC) 1907/2006 Annex XVII are complied with, the base material is suitable for the production of handles or saddles. In addition to the vehicle parts, DEKRA also tests the pollutant emissions of clothing, helmets, and accessories at its laboratory in Stuttgart.
