Fraass Breaking Point Apparatus

Product Code : EL-BTLE-10448

Fraass Breaking Point Apparatus (code EL-BTLE-10448) is a cooling and bending set for finding the breaking point of solid and semisolid bitumen, defined as the temperature at which a thin bitumen film on a metal plaque first shows cracks as it is cooled and flexed under specified conditions. The set comprises a stainless steel plaque, the cooling and bending apparatus, an IP 42C thermometer reading -38 °C to +30 °C, a plate and a stand.

Specifications

What Is the Fraass Breaking Point Apparatus Used For?

Low-temperature brittleness matters for paving binders in cold climates and for roofing and sealing bitumens, which have to flex in winter without cracking. A thin film of the bitumen is spread on the stainless steel plaque, the plaque is fitted to the bending apparatus and cooled at a steady rate, and at intervals it is flexed and released; the thermometer is read at the moment the first crack appears in the film, giving the breaking point. The standard listed for it is EN 12593.

What to Specify When Ordering

• Quantity — the number of apparatus required.

Frequently Asked Questions

What does the Fraass Breaking Point Apparatus determine?
It finds the breaking point of solid and semisolid bitumen: the temperature at which the bitumen first becomes brittle, seen as cracks in a thin film flexed on a metal plaque as it cools.

What parts make up the apparatus?
It consists of a stainless steel plaque, the cooling and bending apparatus, an IP 42C thermometer, a plate and a stand on which the assembly is mounted.

What range does the thermometer cover?
The IP 42C thermometer reads from -38 °C to +30 °C, the span within which the breaking point of the bitumen film is observed.

Why is a breaking point test carried out?
It shows how a bitumen behaves at low temperature, which matters where pavements, roofing or seals must bend in cold weather without cracking.

Which standard describes the breaking point test?
The standard listed for it is EN 12593, which sets out the specified cooling and flexing conditions for the breaking point test.
