1、Designation: D1636 99 (Reapproved 2012)Standard Specification forAllyl Molding Compounds1This standard is issued under the fixed designation D1636; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number
2、 in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers compression molding,thermosetting, allyl compounds as further defined in Section 3.1.2 The values stated in SI uni
3、ts are to be regarded asstandard. No other units of measurement are included in thisstandard.NOTE 1The properties included in this specification are those requiredto identify the molding compounds covered. There may be other require-ments necessary to identify particular characteristics. These will
4、be addedto the specification as their inclusion becomes generally desirable and thenecessary test data and methods become available.NOTE 2There is no similar or equivalent ISO standard.2.

Classification3.1 This specification provides for the identification of threetypes of allyl molding compounds, based on the general type offiller employed in their manufacture, which shall be
8、 distin-guished by the requirements prescribed in Table 1.Type IHigh-strength materials, glass-fiber reinforced.Type IIGeneral-purpose mineral filled.Type IIIGeneral-purpose synthetic fiber filler.3.2 Types I and II may be subdivided into four classesaccording to resin composition and use as follows
9、:Class ADiallyl ortho-phthalate resin, nonflame-retardant.Class BDiallyl ortho-phthalate resin, flame-retardant.Class CDiallyl meta-phthalate resin nonflame-retardant.Class DDiallyl meta-phthalate resin, flame-retardant.3.3 The four classes of Type I are subdivided as follows:ClassesA, B, C, and D i
10、nto four grades. For Type II each of thefour classes is subdivided into two grades. For Type III onlyClass A compounds are produced and are available in threegrades.4. General Requirements4.1 The molding compound shall be of uniform compositionand so compounded as to conform to the requirements of t
11、hisspecification.4.2 Although other than allyl resin may be added for flameresistance and other purposes, the major part of the resinportion shall be diallyl ortho-phthalate or diallyl meta-phthalate.4.3 The apparent density, bulk factor, particle size, physicalform, and color of the compounds shall
12、 be as agreed uponbetween the purchaser and supplier.5. Detail Requirements5.1 Average results obtained on test specimens, eachcompression-molded using the manufacturers recommendedtechniques, shall conform to the requirements listed in Table 2.6. Sampling6.1 Adequate statistical sampling shall be u
13、sed.6.2 Abatch of molding compound shall be considered a unitof manufacture and may consist of a blend of two or moreproduction runs of the same material.1This specification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.16 on Thermose

16、ed States1NOTE 3Some molding compounds are light and fluffy. The resin mayhave a tendency to separate out to a degree and should be thoroughlymixed before sampling.7. Specimen Preparation7.1 Test specimens shall be compression molded in accor-dance with Practice D5224.8. Conditioning8.1 Conditioning
17、Molded test specimens of allyl moldingcompounds shall be conditioned in accordance with ProcedureB of Practice D618, unless otherwise specified in the testmethods or in this specification.8.2 Tests shall be conducted in the standard laboratoryatmosphere of 23 6 2C and 50 6 5 % relative humidity,unle
18、ss otherwise specified in the test methods or in thisspecification.9. Test Methods39.1 The properties enumerated in this specification shall bedetermined in accordance with the following methods:9.2 Impact Resistance (Izod)Test Method D256, MethodA. Test specimens shall be 12.7 by 12.7 by 63.5 mm.9.
19、3 Flexural StrengthTest Methods D790 Procedure A.Test specimens shall be 6.4 by 12.7 by 127-mm bars testedparallel to molding pressure.9.4 Permittivity and Dissipation FactorTest MethodsD150. Measure the permittivity and dissipation factor at 1 kHzand 1 MHz after conditioning by Procedure B of Pract
20、iceD618. Determine permittivity and dissipation factor afterconditioning 48 h at 50C followed by Procedure D of PracticeD618. Use 102 by 3.2-mm disks for 1 kHz frequency and 51 by3.2-mm disks for 1 MHz frequency.9.5 Insulation ResistanceTest Methods D257, using a3.2-mm thick by 102-mm diameter disk
21、fitted with bindingpost electrodes of the type shown in the figure illustratingBinding-Post Electrodes for Flat, Solid Specimens of TestMethods D257. Cut two sections from the disk so that thesection under test is similar to the figure cited above. Scrubwith soapy water, rinse in distilled water, an
22、d rinse withisopropyl alcohol. Air dry the sample before assembly, usingstainless steel terminals which have been washed in isopropylalcohol. The use of clean cotton or polyethylene gloves duringassembly is required since skin oils contaminate the plasticsurface and have been shown to seriously affe
23、ct results. Insertone binding post through a hole drilled through the center ofthe disk. Space the other two electrodes 32 mm from the centerelectrode. Make test measurements between the center elec-trode and each of the other binding posts. The machine screwand washers shall be of stainless steel,
24、the screw of a size tomatch the washer size specified in the figure illustratingBinding-Post Electrodes for Flat, Solid Specimens of TestMethods D257. Two specimens may then be mounted in awide-mouth jar with the leads going through a TFE-fluorocarbon cover. Condition each specimen 720 h at 60Cand 9
25、5 % relative humidity, and measure the insulation resis-tance under the same conditions without removal from theenvironmental chamber.9.6 Flame ResistanceMethod II under Flame Resistanceof Test Method D229. The specimen shall be 12.7 by 12.7 by127 mm.9.7 Oxygen IndexTest Method D2863. Test specimens
26、shall be 3.2 by 6.4 by 127 mm.10. Inspection10.1 Inspection of the compound shall be agreed uponbetween the purchaser and supplier as part of the purchasecontract.11. Rejection and Rehearing11.1 Compound that fails to conform with the requirementsof this specification may be rejected. Rejection shou
27、ld bereported to the producer or supplier promptly and in writing. Incase of dissatisfaction with the results of the test, the produceror supplier may make claim for a rehearing.NOTE 4In the case of short shelf-life materials it is the responsibilityof the purchaser to expedite the tests and to keep
28、 the material at optimumstorage conditions until returned in case of failure.12. Packaging and Package Marking12.1 PackagingThe compound shall be packaged in stan-dard commercial containers so constructed as to ensure accep-tance by common or other carriers for safe transportation at thelowest rate
29、to the point of delivery, unless otherwise specifiedin the contract or order.12.2 Package MarkingShipping containers shall bemarked with the name of the compound, type, class, grade,color lot or batch number, limiting shelf-life data in commonstorage, the quantity contained therein as defined by the
