IEC 61010-1 2001
The scope of 61010-1 specifies.... general safety requirements for electrical equipment intended for professional, industrial process, and educational use, including equipment and computing devices for :
The scope also makes it clear that this standard does not apply to Information Technology Equipment. In fact, it also states that computing equipment that falls under the scope of 60950 and which complies with that standard can be used with equipment within the scope of this standard.
This is generally interpreted to mean that no additional testing is required even if the computing device is built into the 61010-1 equipment. One common item is power supplies approved to 60950, which are often used in 61010-1 equipment.
Because 61010-1 covers a wide range of equipment used in a variety of conditions greater reliance was placed on testing. The actual standard is far smaller than 60950 but the required tests to show compliance are significantly more onerous.
Creepage Distance and Clearance
The difficulty is that many products use power supplies tested to 60950-1 and these typically are not examined for the additional clearances required at higher altitude. You need to give careful consideration to your specified altitude since this can cause significant problems in determining the acceptability of components.
