1、Designation:D334490(Reapproved 2015)Standard Test Method forTotal Wax Content of Corrugated Paperboard1This standard is issued under the fixed designation D3344;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revisio
2、n.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of the weightof wax that is present in a specimen of wax-treated corrugatedpaperboard.The tes
3、t method is applicable to specimens thathave been waxed by either impregnation(saturation)opera-tions or coating operations,or combinations of such operations.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.3 This standard
4、 does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For precautionarystatement,see 5.4
5、and 7.2.2.Terminology2.1 Definitions:2.1.1 weight of applied wax coatingthe weight of wax thathas been applied to the corrugated board as a coating,ex-pressed as weight per unit area,usually grams of coating persquare metre or pounds of coating per thousand square feet ofboard covered.NOTE1When it i
6、s known that a wax-coated specimen has noimpregnating wax present,this extraction procedure is normally calcu-lated to express the data as“weight of applied wax coating.”2.1.2 weight percent wax contentthe weight percent ofwax present in and on corrugated board relative to the weightof unwaxed board
7、 substrate measured at 23 C(73 F)and50%relative humidity.3.Summary of Test Method3.1 The total quantity of wax associated with the corrugatedboard specimen is determined by extracting the wax from theboard and evaporating the extract to dryness.4.Significance and Use4.1 Many of the functional proper
8、ties of wax-treated corru-gated paperboard and cartons are dependent on the amount ofwax present.4.2 In the case of wax-saturated,or wax-impregnated,paperboard the principal concern is with the weight of waxused relative to the weight of paperboard present,that is,theweight percent content or pickup
9、.In some applications thesaturating wax may be deposited in the three elements of thecorrugated board in such a way as to individually control theamount in each element,that is,the medium and the twofacings.4.3 In the case of wax-coated corrugated paperboard theprincipal concern is the weight of wax
10、 on the board surface perunit area.The functional values of the wax coating as a barrieror a decorative coating are dependent,in part,on the amount ofwax in the continuous surface layer,relative to the areacovered.The weight of coating relative to the weight ofsubstrate is not usually a concern with
