Standard Specification for Glass-Fiber-Reinforced Polyester Plastic Panels

Standard Specification for Glass-Fiber-Reinforced Polyester Plastic Panels

ABSTRACT
This specification covers glass-fiber reinforced polyester plastic panels intended for use in construction. Light transmitting panels covered by this specification are divided into two types, based on relative response to a laboratory flammability test: Type CC1 for limited flammability and Type CC2 for general purpose. These types may be further subdivided by grades based on relative response to weathering tests: Grade 1 for weather resistance and Grade 2 for general purpose. The polyester resin used in the panels shall be a thermosetting styrenated and acrylated polyester resin composed of polymeric esters in which the recurring ester groups are an integral part of the main polymer chain. The resin shall be reinforced with glass fibers. The polyester resin may contain additives for various purposes. The materials shall be tested for water absorption, tensile strength, linear thermal expansion, and flexural strength.
SCOPE
1.1 This specification covers the classification, materials of construction, workmanship, minimum physical requirements, and methods of testing glass-fiber reinforced polyester plastic panels intended for use in construction. Panels for specialized or unique applications have the potential to require values significantly above or below those stated in this specification. Recommended practices for certain specific applications are included as Appendix X1. This specification is not intended to restrict or limit technological changes affecting performance when those changes are agreed upon between the purchaser and the seller.  
1.2 Supplementary information on chemical resistance, resistance to heat, and installation practices are provided in Appendix X1.  
1.3 The classification of these plastic panels into types based on relative response to a laboratory test shall not be considered a fire hazard classification.  
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in Tables and Figures) shall not be considered as requirements of this standard.  
1.6 Fire properties are determined by using laboratory flammability tests (Test Methods D635, D1929, and E84).  
1.6.1 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.  
1.6.2 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.7 The following precautionary caveat pertains only to the test method portion, Section 8 of this specification. This specification 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 specification to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.  
Note 1: There is no known ISO equivalent to this standard.  
1.8 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.

Standard Classification System and Basis for Specification for Reinforced and Filled Poly(Phenylene Sulfide) (PPS) Injection Molding and Extrusion Materials Using ASTM Methods

ABSTRACT
This classification system covers reinforced and filled poly(phenylene sulfide) (PPS) materials suitable for injection molding and extrusion. This classification system is not intended for the selection of materials, but only as a means to call out plastic materials to be used for the manufacture of parts. The physical properties of the materials must meet the required tensile strength, flexural modulus, Izod impact strength, flexural strength, and density.
SCOPE
1.1 This classification system covers reinforced and filled poly(phenylene sulfide) materials suitable for injection molding and extrusion.  
1.2 This classification system is not intended for the selection of materials, but only as a means to call out plastic materials to be used for the manufacture of parts. The selection of these materials shall be made by personnel with expertise in the plastics field where the environment, inherent properties of the materials, performance of the parts, part design, manufacturing process, and economics are considered.  
1.3 The properties included in this classification system are those required to identify the compositions covered. If necessary, other requirements identifying particular characteristics important to specific applications shall be designated by using the suffixes given in Section 5 or Classification System D4000.  
1.4 The values stated in SI units are to be regarded as the standard.
Note 1: There is no known ISO equivalent to this standard.
Note 2: ASTM Standard D6358 provides a classification system for the same materials covered in this standard, along with additional PPS materials, with the major difference being its use of ISO test methods, versus the use of ASTM test methods in this standard. The user of this standard is encouraged to evaluate switching to the use of Standard D6358 as it is more up to date with current practices.  
1.5 This precautionary statement pertains only to the test method portion of this classification system, Section 12. 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.  
1.6 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.

ASTM D3916-22(Test Method)
Standard Test Method for Tensile Properties of Pultruded Glass-Fiber-Reinforced Plastic Rod

SIGNIFICANCE AND USE
4.1 The high axial-tensile strength and the low transverse-compressive strength of pultruded rod combine to present some unique problems in determining the tensile strength of this material with conventional test grips. The high transverse-compressive forces generated in the conventional method of gripping tend to crush the rod, thereby causing premature failure. In this test method, aluminum-alloy tabs contoured to the shape of the rod reduce the compressive forces imparted to the rod, thus overcoming the deleterious influence of conventional test grips.  
4.2 Tensile properties are influenced by specimen preparation, strain rate, thermal history, and environmental conditions at the time of testing. Consequently, where precise comparative results are desired, these factors must be carefully controlled.  
4.3 Tensile properties provide useful data for many engineering design purposes. However, due to the high sensitivity of these properties to strain rate, temperature, and other environmental conditions, data obtained by this test method shall not, by themselves, be considered for applications involving load-time scales or environmental conditions that differ widely from the test conditions. In cases where such dissimilarities are apparent, the sensitivities to strain rate, including impact and creep, as well as to the environment, shall be determined over a wide range of conditions as dictated by the anticipated service requirements.
SCOPE
1.1 This test method describes a procedure for determining the tensile properties of a pultruded, glass-fiber-reinforced thermosetting plastic rod of diameters ranging from 2.03 mm (0.08 in.) to 12.7 mm (0.5 in.). Test Method D7205/D7205M is an alternative test method to determine tensile properties of fiber-reinforced composite rods of diameters bigger than 12.7 mm (0.5 in.).  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 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 hazards statements are given in 6.1 and 8.4.3.
Note 1: There is no known ISO equivalent to this standard.  
1.4 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.

Standard Test Method for Water Absorption of Plastics

SIGNIFICANCE AND USE
4.1 This test method for rate of water absorption has two chief functions: first, as a guide to the proportion of water absorbed by a material and consequently, in those cases where the relationships between moisture and electrical or mechanical properties, dimensions, or appearance have been determined, as a guide to the effects of exposure to water or humid conditions on such properties; and second, as a control test on the uniformity of a product. This second function is particularly applicable to sheet, rod, and tube arms when the test is made on the finished product.  
4.2 Comparison of water absorption values of various plastics made on the basis of values obtained in accordance with 8.1 and 8.4 have been found useful.  
4.3 Ideal diffusion of liquids4 into polymers is a function of the square root of immersion time. Time to saturation is strongly dependent on specimen thickness. For example, Table 1 shows the time to approximate time saturation for various thickness of nylon-6.  
4.4 The moisture content of a plastic is very intimately related to such properties as electrical insulation resistance, dielectric losses, mechanical strength, appearance, and dimensions. The effect upon these properties of change in moisture content due to water absorption depends largely on the type of exposure (by immersion in water or by exposure to high humidity), shape of the part, and inherent properties of the plastic. With nonhomogeneous materials, such as laminated forms, the rate of water absorption is sometimes known to be widely different through each edge and surface. Even for otherwise homogeneous materials, it has been observed to be slightly greater through cut edges than through molded surfaces. Consequently, attempts to correlate water absorption with the surface area must generally be limited to closely related materials and to similarly shaped specimens: For materials of widely varying density, relation between water-absorption values on a volume as well as ...
SCOPE
1.1 This test method covers the determination of the relative rate of absorption of water by plastics when immersed. This test method is intended to apply to the testing of all types of plastics, including cast, hot-molded, and cold-molded resinous products, and both homogeneous and laminated plastics in rod and tube form and in sheets 0.13 mm (0.005 in.) or greater in thickness.  
1.2 The values given in SI units are to be regarded as standard. The values stated in parentheses are for information only.
Note 1: This test method and ISO 62 are technically equivalent when the test specimen described in 6.2 is used.  
1.3 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.  
1.4 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.

Standard Classification System and Basis for Specification for Polycarbonate (PC) Unfilled and Reinforced Material

ABSTRACT
This specification covers unfilled and reinforced polycarbonate and polycarbonate copolymer materials suitable for injection molding, blow molding, and extrusion. Some of these compositions may also find use for compression molding or application from solution. Unfilled polycarbonate materials are classified into groups according to their composition. The groups are Group 01, Group 02, Group 03, Group 04, Group 05, and Group 06. These groups are subdivided into classes which are Class 0, Class 1, Class 2, Class 3, and Class 4 and these classes can be further be subdivided into grades which are Grade 1, Grade 2, Grade 3, Grade 4, Grade 5, Grade 6, Grade 7 and Grade 0. Different tests shall be conducted in order to determine the following properties of polymer materials: Izod impact strength, flexural modulus, tensile strength, and deflection temperature.
SCOPE
1.1 This classification system covers unfilled and reinforced polycarbonate and polycarbonate copolymer materials suitable for injection molding, blow molding, and extrusion. Some of these compositions may also find use for compression molding or application from solution. This classification system allows for the use of recycled materials provided that all specification requirements are met.  
1.2 The properties in this classification system are those required for identifying the compositions covered. Other requirements necessary for identifying particular characteristics important to specific applications are normally specified by using the suffixes in accordance with Section 5.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This classification system and subsequent line callout (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection should be made by those having expertise in the plastic field only after consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered in this standard.
Note 1: This classification system and ISO 21305-1 and ISO 21305-2 address the same subject matter, but differ in technical content.  
1.5 The following precautionary caveat pertains only to the test methods portion, Section 12, of this classification system. 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.  
1.6 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.

Standard Practice for Determining Chemical Resistance of Thermosetting Resins Used in Glass-Fiber-Reinforced Structures Intended for Liquid Service

SIGNIFICANCE AND USE
4.1 The results obtained by this practice shall serve as a guide in, but not as the sole basis for, selection of a thermosetting resin used in an RTP structure. No attempt has been made to incorporate into the practice all the various factors that will potentially affect the serviceability of an RTP structure when subjected to chemical environments. These factors will potentially include stress, different resin-to-glass ratios, and multiple veils.
SCOPE
1.1 This practice is designed to evaluate, in an unstressed state, the chemical resistance of thermosetting resins used in the fabrication of reinforced thermosetting plastic (RTP) laminates. This practice provides for the determination of changes in the properties, described as follows, of the test specimens and test reagent after exposure of the specimens to the reagent: hardness of specimens, weight change thickness, appearance of specimens, appearance of immersion media, and flexural strength and modulus.  
1.1.1 This practice is also useful to evaluate other factors, such as surfacing veils and the effect of resin additives, on the chemical resistance of the resin.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Note 1: There is no known ISO equivalent to this standard.

Standard Test Method for Bearing Response of Polymer Matrix Composite Laminates

SIGNIFICANCE AND USE
5.1 Refer to Guide D8509.
SCOPE
1.1 This test method covers the bearing response of pinned or fastened joints using multi-directional polymer matrix composite laminates reinforced by high-modulus fibers by double-shear tensile loading (Procedure A), single-shear tensile or compressive loading of a two-piece specimen (Procedure B), single-shear tensile loading of a one-piece specimen (Procedure C), or double-shear compressive loading (Procedure D). Standard specimen configurations using fixed values of test parameters are described for each procedure. However, when fully documented in the test report, a number of test parameters may be optionally varied. The composite material forms are limited to continuous-fiber or discontinuous-fiber (tape or fabric, or both) reinforced composites for which the laminate is balanced and symmetric with respect to the test direction. The range of acceptable test laminates and thicknesses are described in 8.2.1.  
1.2 This test method is consistent with the recommendations of MIL-HDBK-17, which describes the desirable attributes of a bearing response test method.  
1.3 The multi-fastener test configurations described in this test method are similar to those used by industry to investigate the bypass portion of the bearing bypass interaction response for bolted joints, where the specimen may produce either a bearing failure mode or a bypass failure mode. Note that the scope of this test method is limited to bearing and fastener failure modes. Use Test Method D7248/D7248M for by-pass testing.  
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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4.1 Within the text the inch-pound units are shown in brackets.  
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.

Standard Test Method for Open-Hole Tensile Strength of Polymer Matrix Composite Laminates

SIGNIFICANCE AND USE
5.1 Refer to Guide D8509.
SCOPE
1.1 This test method determines the open-hole tensile strength of multidirectional polymer matrix composite laminates reinforced by high-modulus fibers. The composite material forms are limited to continuous-fiber or discontinuous-fiber (tape or fabric, or both) reinforced composites in which the laminate is balanced and symmetric with respect to the test direction. The range of acceptable test laminates and thicknesses are described in 8.2.1.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
