Different resin floors have different degrees of slip resistance, you need to fully research what is right for you.
The slip resistance of a floor should ALWAYS be measured under production conditions. Most floors offer good slip resistance in dry conditions therefore it is easy for suppliers to provide acceptable results.
There are a number of test methods used to determine slip resistance, the Pendulum test is most common. This method measures the coefficient of friction and relates to a PTV value, anything >40 is low risk of slip.
Another method is the German Ramp Test method which produces an R rating. The rating scale can be confusing and can often lead to misinterpretation and coincidently the wrong specification. The scale runs from R9-R13, with R9 being the most slippery of floor surfaces. The misconception is that the scale runs from R1 and therefore in some Cases R9 is specified as a slip resistant floor, however this is not the case.
A few questions you should think about asking before deciding which system to install:
Q: Can the flooring suppliers provide slip test data?
Q: Are these results tested in wet and dry conditions?
Q: Have these tests been undertaken with different footwear sole materials?
Q: Do the results provide adequate readings under your production conditions?
