1、Designation: D5869/D5869M 07a (Reapproved 2018)1Standard Practice forDark Oven Heat Exposure of Roofing and WaterproofingMaterials1This standard is issued under the fixed designation D5869/D5869M; the number immediately following the designation indicates theyear of original adoption or, in the case

2、 of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in January 2018.1. Scope1.1 This practice establishes a

3、 procedure and conditions oftemperature and time for heat exposure of roofing and water-proofing materials and systems in the presence of air.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equiva

4、lents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of

5、this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the D

Terminology3.1 DefinitionsFor definitions of terms used in thispractice, refer to Terminologies D883, D1079, and D1566.4. Summary of Practice4.1 Specimens of roofing and waterproofing materials areexposed to

9、 heat in a dark forced-ventilation oven at a specifiedelevated temperature for a known period of time.4.2 This practice specifies an exposure temperature of 70 63C 158 6 5F in a forced-ventilation oven.4.3 This practice permits the selection of the duration ofheat exposure from three specified time

10、periods, which are 35,90, and 180 6 0.25 consecutive days. The duration selectedmust be included in any report of results obtained by using thispractice.NOTE 1The time period to be used should be specified in any standardthat refers to this practice. European standards for polymer-modifiedbituminous

11、 materials specify 180 days at 70C. For research purposes,selection of other time periods and temperatures are permitted, providedthat the precise duration is stated in any report of results.4.4 This practice is also used to condition test specimens fortime periods much shorter than 35 days for the

12、purpose ofconditioning material before testing. When used for thispurpose, the shorter conditioning time shall be specified in anyreport of test results.5. Significance and Use5.1 Roofing and waterproofing materials and systems un-dergo changes in physical properties as a result of beingsubjected to

13、 heat. They also undergo changes in physicalproperties as they age in service. Since service conditions varywidely, any relationship between changes observed in thispractice and changes in service must be established by the userof this practice.1This practice is under the jurisdiction ofASTM Committ
