4. Repeatability and reproducibility
ISO 5660-1 standard
Paragraph 3 of Annex C of ISO 5660-1 deals with repeatability, noted r, and reproducibility, noted R.
The data are derived from a series of interlaboratory tests organized by ISO/TC 92/sc 1/WG 5 and supplemented by a similar series of tests carried out by ASTM E05 SC 21 TG 60.
Repeatability and reproducibility values at the 95% confidence level were calculated for the complete data set for just five features of the calorimeter cone test.
These r and R values are equal to 2.8 the appropriate standard deviation.
The range of mean values over which the fit was obtained is also indicated.
The values in table 34 are given for non-intumescent...
