TECHNICAL FIELDS

 

B.C.R.A. METHOD

The B.C.R.A. method is an instrumental method that measures the dynamic friction (μ) that a surface must meet to be considered as anti-slip (μ must be ≥ 0.40 both for the leather slippery element and for the hard rubber slippery element on wet floors):

 

COEFFICIENT OF DYNAMIC FRICTION

μ ≤ 0,19

DANGEROUS SLIPPERINESS

0,20 μ 0,39

EXCESS SLIPPERINESS

0,40 μ 0,74

SATISFACTORY FRICTION

μ 0,75

EXCELLENT FRICTION

 

ASTM C1028 METHOD

The American ASTM method is an instrumental method that measures the static friction (S.C.O.F.).

 

COEFFICIENT OF STATIC FRICTION

0,50

DANGEROUS SLIPPERINESS

0,50÷0,60

SATISFACTORY FRICTION

0,60

ANTI-SLIP

 

DIN METHODS

The German DIN methods often used in Italy and also called “ramp tests” or “inclined platform tests” are split into:

V-SHADE

The V-Shade classification indicates the colour shading level of a product, that is to say the chromatic and/or surface variation among tiles of the same collection. A strong colour shading is typical of ceramic collections that reproduce natural stones and marble. A moderate colour shading is typical of ceramic collections for which a homogeneous chromatic surface is an aesthetic feature of contemporary design.
