Standard Test Method for Extruded and Compression-Molded Shapes Made from Polyetherimide (PEI)

Standard Test Method for Extruded and Compression-Molded Shapes Made from Polyetherimide (PEI)

ABSTRACT
This test method covers requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded and compression-molded sheet, plate, rod and tubular bar manufactured from polyetherimide (PEI) resins. The type of PEI extruded shape shall be categorized by class depending on composition. Every class of PEI shape shall be categorized into one grade for virgin unfilled products. The type and class shall be further differentiated based on dimensional tolerances and dimensional stability (based on elevated temperature excursion testing). Grades 1 and 2 materials are produced with the closest commercial tolerances and lowest stress levels for machined parts. The type, class, and grade is further differentiated based on dimensional stability (elevated temperature excursion test). Tensile strength at break, elongation at break, flexural modulus, izod impact, and tensile modulus (tangent) shall be tested to meet the requirements prescribed. The plate specimens, sheet specimens, rod specimens, and tubular bar specimens shall be tested to meet the requirements prescribed.
SCOPE
1.1 This test method covers requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded and compression-molded sheet, plate, rod and tubular bar manufactured from polyetherimide (PEI) resins.
1.2 The properties included in this test method are those required for the compositions covered. It is possible that other requirements will be necessary to identify particular characteristics important to specialized applications. These shall be agreed upon between the user and the supplier, by using the suffixes as given in Section 5.
1.3 This test method does not allow for the use of recycled plastics (as defined in Guide D 5033).
1.4 The values stated in inch-pound units are regarded as standard in all property and dimensional tables. For reference purposes, SI units are also included in Table 1 and Table S-PEI.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.Note 1
There is no similar or equivalent ISO standard.

Standard Test Methods for Determination of Gel Content and Swell Ratio of Crosslinked Ethylene Plastics

SIGNIFICANCE AND USE
5.1 Many important properties of crosslinked ethylene plastics vary with the gel content. Hence, determination of the gel content provides a means of both controlling the process and rating the quality of finished products.  
5.2 Extraction tests permit verification of the proper gel content of any given crosslinked ethylene plastic and they also permit comparison between different crosslinked ethylene plastics, including those containing fillers, provided that, for the latter, the following conditions are met:  
5.2.1 The filler is not soluble in either decahydronaphthalene or xylenes at the extraction temperature.  
5.2.2 The amount of filler present in the compound either is known or will be determined by other means.  
5.2.3 Sufficient crosslinking has been achieved to prevent migration of filler during the extraction. Usually it has been found that, at extraction levels up to 50 %, the extractant remains clear and free of filler.  
5.3 A suitable antioxidant is added to the extractant to inhibit possible oxidative degradation at the extraction temperatures.  
5.4 Before proceeding with this test method, reference shall be made to the specification of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters, or a combination thereof, covered in the materials specification shall take precedence over those mentioned in this test method. If there are no material specifications, then the default conditions apply.
SCOPE
1.1 The gel content (insoluble fraction) produced in ethylene plastics by crosslinking is determined by extracting with solvents such as decahydronaphthalene or xylenes. The methods described herein are applicable to crosslinked ethylene plastics of all densities, including those containing fillers, and all provide corrections for the inert fillers present in some of those compounds.  
1.2 Test Method A, which permits most complete extraction in least time, is to be used for referee tests, but two alternative nonreferee Test Methods B and C are also described. Test Method B differs from the referee test method only in sample preparation; that is, it requires use of shavings taken at selected points in cable insulation, for example, rather than the ground sample required by the referee test method. Because the shaved particles are larger, less total surface per sample is exposed to the extractant, so this test method ordinarily yields extraction values about 1 to 2 % lower than the referee method. Test Method C requires that a specimen in one piece be extracted in xylenes at a constant temperature of 110°C. At this temperature and with a one-piece specimen, even less extraction occurs (from 3 to 9 % less than the referee test method), this method permits swell ratio (a measure of the degree of crosslinking in the gel phase) be determined.  
1.3 Extraction tests are made on articles of any shape. They have been particularly useful for electrical insulations since specimens can be selected from those portions of the insulation most susceptible to insufficient crosslinking.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
Note 1: This test method is equivalent to ISO 10147, Method B. It is not equivalent to ISO 10147 in any other measurement or section.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Sections 6, 9, and 24.

Standard Test Method for Determination of Xylene Solubles in Propylene Plastics

SIGNIFICANCE AND USE
5.1 The results of this test provide a relative measure of the total soluble fraction of polypropylene homopolymers and copolymers. The soluble fraction approximately correlates to the amorphous fraction in the polypropylene. Xylene is widely used for determining the soluble fraction in polypropylene as it is more specific to the atactic fraction than other solvents. The concentration of a soluble fraction obtained with a specific solvent has been found to relate closely to the performance characteristics of a product in certain applications, for example film and fiber. Data obtained by one solvent and at one precipitation time cannot be compared with data obtained by another solvent or precipitation time, respectively.
SCOPE
1.1 This test method is to be used for determining the 25 °C xylene-soluble fraction of polypropylene homopolymers and copolymers.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: This test method is technically equivalent to ISO 16152.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
