Title:Dynamic Testing Systems for Oxygen Breathing Equipment
Issuing Committee:A-10 Aircraft Oxygen Equipment Committee
Scope: This SAE Aerospace Recommended Practice (ARP) recommends performance requirements for test equipment used in dynamic testing of aviation oxygen breathing equipment. This document describes test equipment and methods used for testing continuous flow, demand and pressure demand regulators and their associated masks as well as filtered protective breathing devices; such articles of oxygen breathing or protective breathing equipment may be tested as individual components or as a complete system. This recommended practice covers but is not limited to the following types and classes of systems: Type I - mechanical breathing simulator (either bellows or piston type) only generating sinusoidal patterns; Type II - mechanical breathing simulator (generally cam-actuated, bellows or piston type or pre-programmed, servocontrolled) generating any shape of breathing pattern; and Type III - pneumatic breathing simulator pre-programmed, servocontrolled generating any shape of breathing pattern; Class A - military aircraft oxygen systems; and Class B - transport category and general aviation oxygen systems.

适用范围
本标准适用于生活饮用水、地面水和废水。样品中含有悬浮物、余氯、钙镁等金属离子、硫化物和有机物时，会产生干扰，含有此类物质时，要作适当的预处理，以消除对测定的影响。范围：最大试份体积为50ml时，铵氮浓度СN可达2mg/L。最低检出浓度：目视法：试份体积为50ml时，最低检出浓度为0.02mg/L。分光光度法：试份体积为50ml时，使用光程长为10mm比色皿时，最低检出浓度为0.05mg/L。灵敏度：使用50ml试份，光程长为10mm比色皿，СN=1.0mg/L，给出的吸光度约为0.2个单位。
