Title:Performance Standard for Child Restraint Systems in Transport Category Airplanes
Issuing Committee:S-9 Cabin Safety Provisions Committee
Scope:This SAE Aerospace Standard (AS) defines minimum performance standards and related qualification criteria for add-on child restraint systems (CRS) which provide protection for small children in passenger seats of transport category airplanes. The AS is not intended to provide design criteria that could be met only by an aircraft-specific CRS. The goal of this standard is to achieve child-occupant protection by specifying a dynamic test method and evaluation criteria for the performance of CRS under emergency landing conditions.

适用范围
本标准规定了基本标准ISO/IEC 7776,ISO/IEC8208和ISO/IEC 8885的功能轮廓，以便在ISDN上操作时提供远程信息处理的低层服务找。同时也注意到了与某些远程信息处理业务有关的终端选择规程，这些业务使用与以上不同的协议。
本标准适用于ISDN上的非话音通信终端，如G4,G3C,G3F以及可视图文等。本标准提供以卜终端接人ISDN的呼叫连接规程和与网有关的下三层通信规程。

Title:Dimensional Compatibility for Commercial Vehicle Wheels to Air Disc Brake Calipers
Issuing Committee:Truck And Bus Wheel Committee
Scope: 1This SAE Recommended Practice defines the clearance line for establishing dimensional compatibility between air disc brake calipers and 22.5 inch diameter disc wheels and includes valve stem consideration. The clearance line establishes the maximum envelope for the caliper and minimum envelope for wheel and valve stems to allow interchangeability.This document addresses dimensional characteristics only and makes no reference to the performance, operational dynamic deflections or heat disipation of the system. It is up to the system integrator to ensure sufficient clearance exists betweent the caliper, wheel and valve stem to provide safe operating conditions. This document is required because the air disc brakes currently in the marketplace, and those of the forseeable future, can not provide accpetable brake performance while complying to the clearance lines defined in SAE J1865 or other packaging requirements. Additionally, J1865 does not take into account the swept area of the valve stem. This is not a concern for drum brake applications where the drum rotates with the wheel and valve stem. However, disc brake applications have the potential for contact between the valve stem and the brake caliper which can result in rapid depressurization of the tire.
