BS EN 2997-012标准适用于航空航天领域中的电气连接器。这些连接器是圆形的，通过螺纹环耦合，可以是防火或非防火的，可以在连续工作温度-65°C至175°C的范围内工作，也可以在连续200°C、峰值260°C的条件下工作。此外，这些连接器还需要使用卡紧螺母进行卡紧。

该标准规定了连接器的尺寸、材料、电气性能、机械性能、环境适应性等方面的要求。其中，连接器的尺寸需要符合标准中规定的尺寸范围，材料需要具有耐高温、耐腐蚀、耐磨损等性能，电气性能需要符合标准中规定的要求，机械性能需要具有耐冲击、耐振动、耐拉伸等性能，环境适应性需要具有耐高温、耐低温、耐湿度、耐盐雾等性能。

此外，该标准还规定了连接器的试验方法和检验要求。试验方法包括电气性能试验、机械性能试验、环境适应性试验等，检验要求包括外观检验、尺寸检验、电气性能检验、机械性能检验、环境适应性检验等。

BS EN 2997-012标准的实施可以提高航空航天领域中电气连接器的质量和可靠性，保证连接器在恶劣的环境条件下正常工作，从而保障飞行安全。
