Additional information
Data from GKA competence centre analytics (2008, 2008 & 2009) are available for three of the streams in this category (64742-49-0: 0.61 mm²/s (static) and 0.44 mPa.s (dynamic) at 20°C and 0.50 mm²/s (static) and 0.35 mPa.s (dynamic) at 40°C, 92128-65-9: 0.64 mm²/s (static) and 0.47 mPa.s (dynamic) at 20°C and 0.53 mm²/s (static) and 0.38 mPa.s (dynamic) at 40°C, 68476-55-1: 0.55 mm²/s (static) and 0.38 mPa.s (dynamic) at 20°C and 0.47 mm²/s (static) at 20°C and 0.32 mPa.s (dynamic) at 40°C). These data will be read across to all category members.
New data areavilable for 4 streams in this category from Intertek (2018):
EC# 295-762-6: 0.556 mm2/s at 40ºC
EC# 270-695-5: 0.5067 mm2/s at 40ºC
EC# 265-151-9: 0.5745 mm2/s at 40ºC
EC#
265-086-6: 0.4879 mm2/s at 40ºC.
The mean of the kinematic viscosity values for the category is 0.60 mm²/s (static) at 20°C and this has been used to complete the 'key value for chemical safety assessment'.
