ANSI/ASTM D5989:1998 尼龙压塑和单体注塑件形状规范

This specification covers requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded and cast sheet, plate, rod and tubular bar manufactured from nylon or monomers. The properties included in this specification are those required for the compositions covered. Requirements necessary to identify particular characteristics important to specialized applications may be described by using the classification system given in Section .This specification allows for the use of recycled plastics (as defined in Guide D 5033). The values stated in inch-pound units are regarded as standard. The values in brackets are for information only. The following precautionary caveat pertains only to the test method portions of this specification. 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. Note 2 -This specification is intended to replace Federal Standard LP-410A and PS 50.

Specification for Extruded and Monomer Cast Shapes Made from Nylon (PA)

ANSI/ASTM D6265:1998 使用挤压机过滤器试验将污染物从聚合物中分离的操作规程

This practice covers a means to separate the unmolten particles, gels, and impurities contaminating a polymer sample. The procedure may be used to remove gels and incompatible materials that may cause imperfections in the final extruded product. Under pressure, most gels will break up or deform and pass through a wire mesh filter, however high molecular weight gels may not break up or deform. If desired, materials isolated on a wire mesh filter can subsequently be identified by spectroscopic or other analytical means. Note 1 -Although not presented as a quantitative method, the procedure presented in this practice may be used to provide quantitative results at the discretion of the user. The user assumes the responsibility to verify the reproducibility of quantitative results. Detection limit depends on the mesh size of the filter screen, but the procedure is generally applicable to the separation of immiscible contaminants present at concentrations greater than 0.1 %. The values stated in SI units are to be regarded as the standard. This standard does not purport to address 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. For specific hazards statements, see Section 8. Note 2 -There is no equivalent ISO standard.
