RKA 5 brochure - .PDF file.

Anton Paar has launched the RKA 5 tester, which uses the ring-and-bell method to determine the softening point of a material. A disc of sample is heated at a controlled rate; this disc supports a steel ball. The temperature at which the ball (enveloped in the sample) falls 25mm is taken as the softening point.

As long as a standardised test protocol is used, this offers a repeatable method of determining the point at which a product becomes mobile.

The RKA 5 is an automatic instrument — in other words, the sample heating and ball drop detection processes are fully automated. This frees up the operator to carry out other work in the lab, as manual ring-and-ball testing can be a labour-intensive operation.

Key features and benefits

  • The RKA 5 features multi-point temperature calibration, a Pt100 sensor and a temperature rate chart during operation.
  • It uses a laser scanner system for detection of the falling ball. This reliable detection system covers the entire width of the liquid bath, reducing erroneous results.
  • The RKA 5 meets the requirements of ASTM D 36, EN 1427, IP 58, JIS K2207, ASTM E 28 and EN 13179.
  • For road-marking materials, the main softening point test in use is the Wilhemi method — the RKA 5 can be used for this test, according to EN 1871-F and DIN 1996-15.
