Product Code:SAE J345
Title:Wet Or Dry Pavement Passenger Car Tire Peak and Locked Wheel Braking Traction
Issuing Committee:Highway Tire Forum Steering Committee
Scope:This SAE Recommended Practice defines the best known techniques for evaluating peak and locked wheel braking traction. It covers an important phase of tire braking traction, namely, the wet or dry pavement straight ahead conditions. However, this is but a small portion of the whole field of tire traction. As test procedures are established for other phases of this complex study, additional supplementary procedures will be written. A discussion of this entire subject is contained in Appendix B to this recommended practice.

Product Code:SAE AMS6495
Title:Steel Bars, Forgings, and Tubing, 1.0Cr - 2.50Ni - 2.0Mo -1.10Si (0.10 - 0.20C), Premium Aircraft-Quality, Electroslag Remelted or Consumable Electrode Vacuum Remelted
Issuing Committee:Ams E Carbon And Low Alloy Steels Committee
Scope:This specification covers a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.These products have been used typically for carburized parts requiring high minimum core hardness with a narrow range, reduced distortion and subject to stringent magnetic particle inspection standards, but usage is not limited to such applications.【英文标准名称】:StandardPracticeforEvaluationofSurveillanceCapsulesfromLight-WaterModeratedNuclearPowerReactorVessels
