ASTM D5113-1997(2005) Standard Test Method for Determining Adhesive Attack on Rigid Cellular Foam《测定硬质多孔泡沫塑料的胶粘剂化学浸蚀的标准试验方法》.pdf

1、Designation: D 5113 97 (Reapproved 2005)Standard Test Method forDetermining Adhesive Attack on Rigid Cellular Foam1This standard is issued under the fixed designation D 5113; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year

2、 of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers a practical means of measuringthe degree of rigid cellular polystyrene (RCPS) foam cavita

3、tiondamage when an adhesive is used to bond this substrate.1.2 The values stated in inch pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It

4、 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.2.

Terminology3.1 Definitions:3.1.1 Many terms in this standard are defined in Terminol-ogy D 907.3.2 Definitions of Terms Specific to This Standard:3.2.1 cavitation damage, nas related to rigid cellularpolystyrene foam, the pitting and wearing away of the surface.3.2.1.1 Discu

6、ssionDamage may include loss of material,surface deformation, or any other changes in microstructure,properties, or appearance.3.3 Abbreviations:3.3.1 RCPSRigid cellular polystyrene.4. Summary of Test Method4.1 This test method consists of testing two RCPS sectionsbonded by adhesive and allowed to s

7、et for 24 h. Beforeevaluation, the degree of cavitation is measured and recorded.5. Significance and Use5.1 Rigid foam such as RCPS is used in the buildingconstruction industry. Because it is sensitive to certain compo-nents contained in adhesives which cause it to dissolve, it isimportant to have a

8、 test method to determine whether anadhesive is compatible with RCPS foam. This test methodwould help the end user decide which adhesive to use withRCPS foam by quantitatively measuring the amount of cavi-tation formed by the components contained in the adhesive.6. Apparatus6.1 Circular Template, wi

9、th an inside diameter of 1.0 in.(25.4 mm) and a depth of14 in. (6.3 mm).6.2 Circulating Air Oven, for elevated temperature testing,capable of being held at 40 6 1C (104 6 1.8F).7. Materials7.1 For the test, use Type IV RCPS foam with a nominalthickness of 1.0 in. (25.4 mm).7.2 If another type is use

10、d, record the type, thickness anddensity.8. Conditioning8.1 Unless otherwise agreed upon by the purchaser and themanufacturer, condition the test specimen and adhesive 24 hprior to testing at 23 6 1C (73.4 6 1.8F) and 50 6 5%relative humidity.9. Procedure9.1 Prepare enough specimens so that two asse

11、mblies aretested at both temperatures.9.1.1 For each test, cut two sections of RCPS into 3 in. (76.2mm) by 3 in. specimens.9.1.2 Place the template in the center of one of the speci-mens.9.1.3 Fill the template with the desired adhesive, taking careto strike off any excess with a flat edge spatula.9

12、.1.4 Immediately remove the template and superimposethe second piece of foamboard on top of the first one. Squeezethe assembly together until the adhesive can be seen squeezingout from between the assembly.9.1.5 Wrap the assembly in a 12.0 in. (304.8 mm) by 12.0in. (304.8 mm) piece of aluminum foil.

16、ectional area).9.4 Use a ruler to measure the maximum depth of thefoams cavitation to the nearest millimetre. Report cavitationas half the total depth of the two glued specimens.9.5 Record cavitation in millimetres (inches).10. Report10.1 Report the following information:10.1.1 Complete identificati
