5、4 SEP2009Thermoset Elastomer Specification SystemRATIONALEIncorporate SAE J2979 into SAE J2884.FOREWORDAn alternate to SAE J200. No global equivalent standard exists.1. SCOPEThis document provides a method/procedure for specifying the properties of vulcanized elastomeric materials (natural rubber or
6、 synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications. This document covers materials that do not contain any re-use; recycled; or regrind materials unless otherwise agreed to by manufacturer and end user. The use o
7、f such materials, including maximum % must be specified using a “Z” suffix.This classification system covers thermoset High Consistency Elastomers (HCEs) only. Thermoplastic Elastomer (TPE) materials are classified using SAE J2558. Silicone Formed In Place Gasket (FIPG) systems such as Room Temperat
8、ure Vulcanized (RTV) Silicones, and Liquid Silicone Rubber (LSR) systems are classified using ASTM F 2468.1.1 PurposeThis classification system is an alternative document to SAE J200.This document utilizes certain elements of SAE J200, SAE J2236 and SAE J2558 along with new elements to build a line
9、call out without the need for laboratory round robins to generate data for table creation/ modification.1.2 Document BasisThe basis for a line call out for any material using this document includes:Elastomer ChemistryMaterial HardnessTensile StrengthElongationContinuous Upper Temperature Resistance
10、(CUTR)IRM 903 Oil Volume Change1.3 Requirements and RecommendationsSAE INTERNATIONAL J2884 Revised JUN2014 Page 2 of 24The creator of a line call out, prior to material testing must have a good grasp of the application requirements and elastomeric material principles. Certain polymer description and
11、 physical property characteristics are required in a line call out and are covered in 1.2 and Section 3. Additional physical property characteristics are discretionary based on the needs of the application, and are covered in Section 4.It is recommended to utilize this document to classify elastomer
12、ic materials for specific applications in order to maintain a minimum length line call out.It is recommended the material manufacturer and the user develop a final line call out for a functioning material based on 30 data points (minimum for statistical analysis) per requirement from 6 different pro
13、duction batch runs minimum for large scale production. Development of a line call out for low volume/ small scale production in which 6 different production batch runs may not be feasible In these cases development may be based on 20 data points per requirement from at least 1 production batch and 3
14、 laboratory lots (or any combination totaling 4 lots, as long as 1 production lot is included). If using this alternative, it is recommended that each production lot be validated to the full line call out prior to use.Production batch runs must be prepared using the production intent equipment param
15、eters (type, size, and other compounding parameters).Test plaques used for physical property evaluations should, as close as possible, mimic the production process, including state of cure.1.4 Example FormatThe format of examples used in each section/subsection lists the basic requirements along wit
16、h the applicable suffix requirement. The examples shall resemble as close as possible, real life materials. The portion of the example to be defined for each subsection are shown in bold print.2.

BASIC REQUIREMENTSBasic requirements must be sp
28、ecified in all line call outs. The basic requirements of a line call out contain a series of letters to describe the Elastomer Chemistry followed by 10 numbers to describe the various basic physical properties of the elastomer system. A space must be left between the acronym(s) and 1stnumber set, an
29、d each subsequent number set that is used in describing a property.3.1 Specifying Basic Physical PropertiesBasic requirements must be specified as Non-Zero letters/ values.IRM 903 is the only exception, since non-polar materials are not expected to have resistance to volume swell in non-polar oils s
30、uch as the IRM 903 (also the Fluid Aging Property Change Table in 4.4.3 does allow a “0” indicating “No Requirement”). Polar materials will have a measure of IRM903 oil resistance and must contain a non-zero value.No zeros (0s) may be used as place holders for any other basic requirement.In a line c
31、all out, the aged portion (168 hour volume change in IRM 903 Oil) cannot be modified by suffix requirements (EOC). If used, an EOC suffix requirement is in addition to the basic requirements.3.1.1 Elastomer ChemistryThis is specified using the appropriate acronym(s) as listed in the table in 3.2.3.1
32、.2 Hardness, Type A DurometerExpressed as Points 5 per ASTM D 2240 1stand 2ndnumbers.NOTE: Delay used in readings is a common source of correlation between laboratories. Materials tested and specified using this document must follow ASTM D 2240, which specifies a delay of 1 0.1 seconds as the defaul
33、t delay, unless an alternate delay is agreed on between supplier and user, and specified using a “Z” (i.e. Zn=ASTM D 2240 determined using a 5 second delay).3.1.3 Tensile StrengthExpressed as MPa minimum per ASTM D 412 Die C 3rdand 4thnumbers. For this basic requirement only, tensile requirements le
34、ss than 10 MPa may be expressed using a decimal. As such as a tensile requirement of 8.5 MPa would be allowable, but 11.7 MPa would not, unless done so using a “Z” Special Requirements modifier.3.1.4 Ultimate ElongationExpressed as % minimum per ASTM D 412 Die C 5th, 6th, and 7thnumbers.3.1.5 Contin
35、uous Upper Temperature Resistance (CUTR) as determined per SAE J22368thand 9thnumber representing temperature from the “Aging Duration and Temperature” table in Section 4.3.1.6 IRM 903 Oil Aged Volume ChangeExpressed as % maximum taken from the “Fluid Aging Property Change Table -Volume Change” colu
