[’OREWORD
I his [l~dian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the ThermalInsuiution Sectional Committee had been zipproved by the Chemical Division Council.
‘1’Ilcusc of’ ceramic fibres as thermal insulation materials began in 1960’s. However, their use has grown since
eaI-ly 1970”s. The use ofceramic iibrcs products as high temperature insulation spread rapidly as a consequence of(IIC energy crisis ivorldwide in the early seventies, These are extensively used as thermal insulation and firercsis[ant inatcria!s besides their core strength as low thermal mass soft refractory lining material.
‘1’IICct~lllpositiorl OF[he Committee responsible for f(mnulation of this standard is given in Annex B.
I’or the purpose of dcciditlg whether a particular requirement of this standard is complied with the final value,observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance withIS 2: 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in theroIIndcd of’f value should be the same as that of the specified value in this standard.

A-2.1 Tests for the conformity to the requirements ofthe specification shall be done on each lot separately.The material to be selected from a lot shall be inaccordance with Table 8.
A.2.2 These rolls shall be selected at random from thelot and to ensure randomness of selection, randomnumber tables shall be used. In case such a table innot available, the following procedure may beadopted:
Starting from any roll in the lot, count them as
1,2,3 ........... upto r and so on, where r is theintegral part of N/n (N being the lot size and nbeing the number of roll to be selected). Everyrth roll thus counted shall be withdrawn fromthe lot to give samples for tests.
A-3 NUMBER OF TESTS
A-3.1 From each of roll selected according to A-2.2test specimens necessary for carrying out the varioustests specified in this standard shall be taken, care beingexercised to exclude some amount of wool from thetop of the roll.
A-3.2 Tests for the determination of all characteristicsspecified in this standard shal I be conducted on eachof the test specimens drawn from the roll as obtainedunder A-3.1.
A-3.3 Criteria for Conformity
The lot shall be declared as conforming to therequirements of this specification, if the different testresults obtained under A-3.2 meet the correspondingrequirements given in the standard individually.
