IEC 60603-6:1987标准规定了边缘插座连接器和印刷电路板连接器的设计、尺寸、材料、性能和试验要求。这些连接器通常用于连接印刷电路板上的电子元件，如集成电路、电容器、电阻器等。连接器的设计必须满足以下要求：

1. 连接器必须能够在印刷电路板上稳定地固定，以确保连接的可靠性和稳定性。

2. 连接器必须能够在连接和断开时保持良好的电气接触，以确保信号传输的可靠性。

3. 连接器必须能够承受机械应力和环境影响，以确保其长期稳定性和可靠性。

4. 连接器必须能够满足特定的电气性能要求，如电阻、电容、电感等。

IEC 60603-6:1987标准规定了连接器的尺寸和材料要求。连接器的尺寸必须满足2.54毫米接触间距的要求，以便与其他标准连接器互换使用。连接器的材料必须具有良好的机械强度、耐热性、耐腐蚀性和电气性能。

IEC 60603-6:1987标准还规定了连接器的性能和试验要求。连接器必须经过机械强度、电气性能、耐热性、耐腐蚀性等方面的测试，以确保其符合标准要求。连接器的测试必须在标准试验条件下进行，以确保测试结果的可比性和准确性。

总之，IEC 60603-6:1987标准规定了连接器的设计、尺寸、材料、性能和试验要求，以确保连接器的互换性和可靠性，适用于频率低于3 MHz的印刷电路板。
