3.10.1.6.3 The classification criteria refer to kinematic viscosity. The following provides the conversion between dynamic and kinematic viscosity

3.10.3.3.1.1 A mixture which contains a total of 10 or more of a substance or substances classified in Category 1, and has a kinematic viscosity of 20.5 mm2 s or less, measured at 40 C, will be classified in Category 1.

3.10.3.3.2.1 A mixture which contains a total of 10 or more of a substance or substances classified in Category 2, and has a kinematic viscosity of 14 mm2 s or less, measured at 40 C, will be classified in Category 2.

But with something like Shimmer, or we have something called the Magic Carpet, embedded sensors in carpet, or camera based systems that we borrowed from sports medicine, we're starting for the first time in those 600 elderly households to collect actual kinematic motion data to understand What are the subtle changes that are occurring that can show us that mom has become risk at falls?
