| New Flash Point Reference Material
available The Institute for Interlaboratory
Studies (iis) did prepare a new Reference Material: n-decane for Flash Point determination.
The material can be used for quality control purposes for Flash Point determinations on Jet Fuel A1.
The Flash Point Reference Material can be ordered in quantities of 100 ml. The certified parameters have passed strict
statistical assessment.
During the interlaboratory studies of September/October 2007 (iis07J02) with 125
laboratories in 59 different countries, the candidate Flash Point Reference
Material has been certified for three types of Flash Point determinations that are all used for
Jet Fuel A1 testing in accordance with the latest version of DefStan 91-91.
The assigned values and its
uncertainties are presented in the following table: Parameter Value Uncertainty Flash Point IP170 / ISO13736, °C 49.6 ± 0.2 Flash Point ASTM D56, °C 50.9 ± 0.5
Flash Point D3828/IP303 & IP523/ISO3679, °C 48.9 ± 0.7 Besides, the following value was also determined for
this RM. This value was not certified, but is for indication only:
Parameter Value Uncertainty Flash Point ASTM D93, °C 54.3 ± 2.7 The Reference Material and the certification report can be ordered at the Institute for Interlaboratory Studies
directly. |
