In this stan ard, ref eren e is made in several places to ISO publcation ac omp nied by a
s ort des ription of the method u ed It is to b u dersto d that this s ort des ription is
me nt for identification purp ses only an that al detai s s ould b taken fom the ISO
publ cation itself
In this stan ard, the definition of “sp cimen” an “ est piece” as defined in ISO 18 are u ed
– sp cimen: a rectan le of p p r or b ard c t to given dimen ion f rom s e ts drawn f rom
selected u its
NOT Ad pte fom 3.4 of ISO 18
– test piece: the q antity of p p r or b ard on whic the determination is car ied out in
ac ordan e with the method of test It may b taken f rom a sp cimen; in some in tan es it
may b the sp cimen itself
NOT Ad pte fom 3.6 of ISO 18

than 16 h in an atmosphere of (2 ? 2) ?C an (5 ? 5) % r.h Perf orm the tests on the test
pieces in this atmosphere
3.2 In cases of dispute u e the f ol owin proced re
Prior to con itionin , dry al sp cimen at 7 ?C to a moisture content b low 4 % Con ition

– Make one determination on e c of the thre con itioned test pieces
– Take the central value as the res lt of the thic nes of a sin le s e t; the other two
