12 Annex A (informtiv) Clrifiction of nominl, mximum nd minimum test vlues A.1 Generl The requested properties s given in this prt of the stndrd EN xxx (i.e. EN xxxx-y), re given s nominl vlues with upper nd lower limits, mximum vlues nd/or minimum vlues. The purpose of this nnex is to clrify the nomenclture nd the ssocited vlues. A.2 Clrifiction of nominl vlue Nominl vlue mens tht the properties of the mteril will hve men vlue equl to the declred vlue. The men vlue is bsed on ll mesured vlues of ll btches of the mnufcturer. The mteril delivered to the customer is normlly only frction of the totlly produced mteril. This my result in tht the ctul vlue on the property of the delivered mteril hs men vlue lower or higher thn the declred vlue. However, the men vlue of the property of the delivered mteril shll not be outside the declred tolernce limits in order to be delivered ccording to the declred properties. These tolernces include inccurcy in the mesurement itself. A.3 Clrifiction of minimum nd mximum vlue Minimum vlue nd mximum vlue mens the men vlue minus (-) nd plus (+) two stndrd devitions, respectively. The minimum nd mximum vlue is bsed on ll mesured vlues of ll btches of the mnufcturer. The delivered mterils hve 97,6 % probbility of being within the minimum nd mximum vlues, thus hving 2,4 % probbility of being outside the minimum nd mximum vlue. This implies tht prt of or ll of the delivered mteril my belong to the frction which is outside the minimum nd mximum vlues. In order to void this, n greement between the mnufcturer nd customer stting tht no mteril shll hve properties bove or below the declred minimum nd mximum vlues, i.e gurnteed minimum or mximum vlues. A.4 Gurnteed minimum nd mximum vlue Gurnteed minimum nd mximum vlue men tht no delivered mteril hs properties below or bove these vlues. When destructive testing is needed the men vlue of the tested mteril (within the sme btch) shll be within the declred minimum nd mximum vlue for tht prticulr test if gurnteed vlues hve been greed. In cse gurnteed vlue is not greed, smple test my hve ny vlue nd still be within the specified rnge. A.5 Extent of testing The extent of testing involved for hs to be greed between the supplier nd the customer. For resin mteril it is norml to obtin the properties from the btch. For core nd fibre mteril, severl of the tests re destructive tests nd hve to be performed on undelivered mteril. 12

13 For core pltes, destructive testing for mechnicl properties cn be performed in the lower rnge of density, while non destructive tests, (dimensions nd density) my be performed on every plte or selection. The extent of testing of fibre mteril is similr s for core mteril, where typicl vlues re obtined from one or more bobbins or n greed selection. 13
