SAE汽车橡胶规范委员会得出结论，鉴于SAE J18是ASTM D的镜像 1056年（第8.01卷），SAE J18将在2005年被淘汰。本SAE推荐规程适用于柔性多孔橡胶产品 被称为海绵橡胶和膨胀橡胶，但不适用于乳胶泡沫橡胶或硬质泡沫橡胶。用于制作一个产品的基本材料 开/闭式泡沫产品可由合成橡胶、天然橡胶、再生橡胶或混合物制成，并可能含有其他聚合物或混合物 可通过有机或无机添加剂改性的化学品，或两者兼有。 这些弹性材料的性能与 硫化橡胶，即（a）通过交联（硫化）将热塑性塑料转化为热固性状态的能力；或 （b） 当拉伸或拉长时，或同时拉伸或拉长时，基本恢复其原始形状。尺寸过小的挤压或模制形状 切割标准试样很难用这些方法进行分类或测试，通常需要特殊的测试程序。万一 本通用规范的规定与特定产品的详细规范或试验方法的规定之间存在冲突， 以后者为准。参考本文件中的试验方法时，应特别说明特定试验 渴望的以国际单位制表示的数值应视为标准。英文单位仅供参考。以下是安全 危险警告仅适用于本文件的试验方法部分:本文件并不旨在解决所有安全问题 与使用相关的问题（如有）。本文件的使用者有责任确保适当的安全和健康 并在使用前确定监管限制的适用性。 注——ASTM D 1056-98和ISO 6916-1与此类似 文件

he SAE Committee on Automotive Rubber Specifications has concluded, that in light of the fact that SAE J18 is a mirror image of ASTM D 1056 (Vol. 8.01), SAE J18 will be eliminated in the year 2005. This SAE Recommended Practice covers flexible cellular rubber products known as sponge rubber and expanded rubber, but does not apply to latex foam rubber or ebonite cellular rubber. The base material for an open/closed cellular product may be made of synthetic, natural, reclaimed rubber, or a mixture, and may contain other polymers or chemicals, or both, which may be modified by organic or inorganic additives. These elastomeric materials have properties similar to those of vulcanized rubber, namely (a) the ability to be converted from a thermoplastic to a thermosetting state by crosslinking (vulcanization) and or (b) substantial recovery of their original shapes when strained or elongated, or both. Extruded or molded shapes of sizes too small for cutting standard test specimens are difficult to classify or test by these methods and will usually require special testing procedures. In case of conflict between the provisions of this general specification and those of detailed specifications or test methods for a particular product, the latter shall take precedence. Reference to the test methods in this document should specifically state the particular test or tests desired. The values stated in SI units are to be regarded as the standard. English units are included for reference only. The following safety hazards caveat pertains only to the test methods portions of this document: This document 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 document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. NOTE -- ASTM D 1056-98 and ISO 6916-1 are similar to this document.
