本标准规定了化学纤维回潮率的试验方法－烘箱法。有争议时采用箱内热称法，将在非标准大气条件下测得的烘干质量修正到标准大气条件下的数值，修正方法见附录A。该法不适用时由相关方商定相应的试验方法。附录B仅适用于涤纶。本标准适用于聚酯（涤纶）、聚酰胺（锦纶）、聚丙烯腈（腈纶）、聚丙烯（丙纶）、聚乙烯醇缩甲醛（维纶）、聚氯乙烯(氯纶)、纤维素纤维等化学纤维回潮率的试验。

Title:Crack Initiation and Growth Considerations for Landing Gear Steel With Emphasis on Aermet 100 (Cancelled Dec 2004)
Issuing Committee:A-5b Gears, Struts And Couplings Committee
Scope: Steel alloys, such as AF1410 (AMS 6527, UNS K92571) and AerMet 100 (AMS 6532), have been developed which have improved Fracture Toughness characteristics compared to the current landing gear steel alloy, 300M (AMS 6419 and AMS 6257, MIL-S-8844, UNS K44220). The 300M steel is the most widely used material in current landing gear designs. It has been successfully used in thousands of applications. The use of the 300M material necessitates a safe life design criterion where components are retired after on-fourth to one-sixth the laboratory test life. This criterion was established in part due to the relative low fracture toughness of low-alloy steel in the 260 to 300 ksi strength range. The high fracture tough alloys give comparable strength levels with an increase in fracture toughness and better resistance to stress corrosion cracking. These alloys may make possible the consideration of new procedures for operation, maintenance, and inspection. For the present, these materials in the 220 to 280 ksi strength range, cannot be certified to damage tolerant design methods. Even though they may not qualify as damage tolerant in single load path applications, the improved mechanical properties alone may justify the consideration of these materials, especially in corrosive environments. In the future, they may allow on-condition maintenance, crack growth monitoring, and increased ptotential for rework. This document identifies several available materials.

In the future, they may allow on-condition maintenance, crack growth monitoring, and increased ptotential for rework. This document identifies several available materials. It compares properties of selected low-alloy steels to the higher alloyed steels. It also compares failure modes, maintenance, and inspection techniques. Although cost should be a factor when considering the material selection for landing gear application, this document will only focus on the technical aspects.selected low-alloy steels to the higher alloyed steels.
