4 Classification
Shaped insulating refractory products are suibdiided litto group,s according to:
a) the temperature at which the permanent change in dimensions, determined in accordance with prENl094-6, 1s2%or less (see Table 1);
b) the bulk density, rounded to two decimal placts determined in accordance with EN 10944, to (hstlngun.sh Clais 1 j)flXlU(tS from ose with the sante grouping according to a) bitt with a higher porosity (see ‘liable 2).
For (1w deteniünation of bulk density, 11w test pieces should be large enough for the desired accuracy to be attained. As opposed to EN 1094-4. the dimensions shall be measured to within ±0,1 nun using eallipen4.
5 Designation
A shaped insulating product shall be designated by the group to which it belongs:
