A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers procedures for determ
3、ining theeffect of freezing and thawing of exterior insulation and finishsystems (EIFS), an EIFS with water-resistive barrier coatings,and water-resistive barrier coatings by itself.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stat

16、ions issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.17.1.2 For sheathing substrates, two sheathing sections shallbe assembled with a 3.2-mm 18-in. joint. The joint shall betreated as it would in its end-use configuration.7.1.3 Apply the water-resistive barrier coa
17、ting over thesubstrate surface in accordance with the manufacturers in-structions. The specimen shall be representative of those usedin actual construction.Allow the water-resistive barrier coatingto dry a minimum of 24 h.7.1.4 The back and sides of the test specimens shall besealed with an impervio
18、us material that need not be thecoating.7.2 EIFS Testing7.2.1 Prepare a minimum of five test specimens measuringa minimum of 150 mm26 in.2 and consisting of the followingmaterials:7.2.1.1 Substrate,7.2.1.2 Water-resistive barrier coating (if applicable),7.2.1.3 Insulation board,7.2.1.4 Reinforcing m
19、esh, and7.2.1.5 Finish.7.2.2 If a water-resistive barrier coating is included as partof the EIFS System, apply the water-resistive barrier coatingover the substrate surface in accordance with the manufactur-ers instructions. The specimen shall be representative of thoseused in actual construction.7.
20、2.3 Secure the insulation board to the substrate or water-resistive barrier coating (where applicable). Apply the basecoat and reinforcing mesh to the surface of the insulation boardincluding the edges. Allow the base coat to cure a minimum of24 h.7.2.4 The back and sides of the test specimens shall
21、 besealed with an impervious material that need not be thewater-resistive barrier coating.8. Conditioning8.1 Allow the test specimens to cure a minimum of 28 daysat room temperature of 22 6 3 C 72 6 5 F and 50 6 5%relative humidity.9. ProcedureNOTE 1There are two test methods,Aand B, that have diffe
22、rent cycletimes and durations. The manufacturer should specify which test(s) to run.9.1 Method A (60 Cycles):9.1.1 Visually observe the test specimens for cracks ordamage. Discard any damaged samples and replace them withsamples prepared and cured in accordance with Sections 7 and8.9.1.2 Submerge th
23、e test specimens (finished side down) inthe water of the thawing tank. Water temperature shall be 24 65.5 C 75 6 10 F.9.1.3 Place a restraining bar across the test specimens toensure the samples remain at a depth of 5 mm 0.20 in.9.1.4 Remove the test specimens from the thawing tank andstand them in
24、the freezing trays.Aspace of at least 12.7 mm 12in. shall separate the test specimens as placed in the trays.Place the trays and their contents in the freezing chamber for20 6 1h.9.1.5 Remove the trays from the freezing chamber after 206 1 h and submerge the test specimens in the water-thawingtank a
25、s shown in 9.1.2 and 9.1.3 for 4 612 h.9.1.6 Freeze the test specimens using the procedure de-scribed in 9.1.4 for one cycle each day of the normal workweek. Following the 4 612 h-thawing after the last freeze-thaw cycle, remove the test specimens from the trays and storethem for 44 6 1 h in the dry
26、ing room. Do not stack or pileunits. Provide a space of at least 25.4 mm 1 in. between alltest specimens. Following this period of air drying, inspect thespecimens, submerge them in the thawing tank for 4 612 h,and again subject them to a normal week of freezing andthawing cycles in accordance with
27、9.1.2 and 9.1.5.NOTE 2If a laboratory has personnel available for testing 7 days aweek, the requirement for storing the test specimens for 44 6 1hinthedrying room following the 4 612 h-thawing after the last freezing cycleof the week may be waived. The test specimens may then be subjected tothis met
28、hod of freezing and thawing for 60 consecutive days.9.1.7 Continue to subject the test specimens to Method A(60 cycles) of freezing and thawing.9.1.8 After completion of Method A, examine the testspecimens for deleterious effects. If deleterious effects occurprior to the completion of Method A, stop
29、 the test and recordthe number of cycles completed.9.2 Method B (10 Cycles):9.2.1 Visually observe the test specimens for cracks ordamage. Discard any damaged samples and replace them withsamples prepared and cured in accordance with Sections 7 and8.9.2.2 Air dry the test specimens at a temperature
30、of 49 C120 F for a minimum of 8 h.9.2.3 Submerge the test specimens (finished side down) inthe thawing tank. Water temperature shall be 24 6 5.5 C 756 10 F.9.2.4 Place a restraining bar across the test specimens toensure the samples remain a depth of 5 mm 0.20 in.9.2.5 Remove the test specimens from
31、 the thawing tank andstand them in the freezing trays.Aspace of at least 12.7 mm 12in. shall separate the test specimens as placed in the trays.Place the trays and their contents in the freezing chamber for16 h. Temperature of the freezer shall be maintained at28.9 C 20 F.9.2.6 Continue to subject t
32、he test specimens to Method B. Ifdeleterious effects occur prior the completion of Method B,stop the test and record the number of cycles completed.9.2.7 After completion of Method B, view the test speci-mens for surface changes, under 5 magnification, for delete-rious effects such as cracking, chec
33、king, crazing, erosion, andso forth.10.
