Terminology3.1 DefinitionsThe definitions of terms used in thesemethods shall be in accordance with Definitions D 1554 andTerminology C 168.3.2 cellulosic fiber insulating boarda fibrous-felted, ho-mogeneous panel
14、 made from ligno-cellulosic fibers (usuallywood or cane) and having a density of less than 31 lb/ft3(497kg/m3) but more than 10 lb/ft3(160 kg/m3).3.2.1 DiscussionCellulosic fiber insulating board. It ischaracterized by an integral bond that is produced by interfelt-ing of the fibers, but which has n
15、ot been consolidated underheat and pressure as a separate stage in manufacture. Othermaterials may be added during manufacture to improve certainproperties.3.3 Definitions of Terms Specific to This Standard:3.3.1 boardrefers to the material as received.3.3.2 samplerefers to the 36 by 48-in. (0.9 by
16、1.2-m)piece cut from a board.3.3.3 test specimenrefers to the test piece cut from asample unless otherwise specified in the test method.3.3.4 sorptiona general term in physical chemistry usedto describe the combined processes of:(1) absorptionrefers to the taking up of matter in bulk byother matter,
17、 for example, the penetration of substances intothe bulk of another solid or liquid.(2) adsorptionrefers to surface retention or adhesion of anextremely thin layer of molecules to the surfaces of solids orliquids with which they are in contact.4. Significance and Use4.1 The test methods contained in
18、 this document are in-tended for cellulosic fiber insulating board as described inSpecification C 208. These test methods examine mechanical,physical and thermal properties, properties related to waterabsorption and water vapor exposure, and flammability relatedproperties.4.2 The results of these te
19、sts may be used to describe theperformance of insulating board and are suitable for use inmaterial specifications.NOTE 1Committee C-16 is in the process of splitting this documentinto discrete test methods categorized by the nature of the test methods.5. Sampling5.1 Selection of BoardsRefer to Speci
20、fication C 208,Section 9 on Sampling.5.2 Size of Sample From each board a sample, 36 by 48in. (0.9 by 1.2 m) shall be cut. When possible, the largerdimension of the sample shall be crosswise of the longerdimension of the board as it is usually obtained. When theindividual boards are less than 36 by
21、48 in. (0.9 by 1.2 m) insize, enough material shall be taken to give the equivalent area.6. Test Conditions6.1 Preconditioning Tests shall be made under prevailingatmospheric conditions except in the case of dispute. Tests thenshall be made in specimens conditioned until equilibrium isobtained in ac
22、cordance with Practice C 870.7. Thickness7.1 ApparatusAn instrument such as a dial gage capableof measuring a 36 by 48 in. (0.9 by 12 m) sample, on which thecontacting surfaces are flat and have a minimum diameter of12in. (13 mm) shall be used. Pressure on the contacting surfacesshall not be greater
23、 than 1 psi (6.9 kPa) nor less than 0.25 psi(1.7 kPa), and the instrument shall read to an accuracy of 0.001in. (0.03 mm).7.2 ProcedureMeasure the thickness at five points, neareach corner and near the center, to an accuracy of 60.001 in.(60.02 mm). Take care that the sample is not deformed whenthe
24、thickness measurements are taken.7.3 Calculation and ReportReport the average of the fivemeasurements as the average thickness of the sample.
