BS EN IEC 62610-6:2020

What is BS EN IEC 62610‑6 about?

BS EN IEC 62610‑6 is the sixth part of the multi series international standard on Mechanical structures for electrical and electronic equipment.

BS EN IEC 62610‑6 deals with thermal management for cabinets by

IEC 60297 and IEC 60917 series, provides compatible measurement methods of recirculation

ratio and bypass ratio which are indicators for defining quality of airflow in the forced air cooling that can be commonly applied to indoor cabinets for mounting subtract and/or chassis-based equipment.

Note: Both recirculation and bypass represent leakage airflows, i.e. detrimental phenomena in terms of cooling efficiency; their measurement is aimed at their mitigation.

Note: This document contains the following:

• The definition of recirculation and bypass flow rates in the cooling of the cabinet,
• The levels of the recirculation ratio RC,
• The definition of the formula for the recirculation ratio RCs of forced air cooling subtract and/or
• Chassis-based equipment installed in the cabinet
• The definition formula of recirculation ratio RCr and bypass rate BPR of the entire cabinet
• The requirements of the measuring method of each temperature necessary for calculating
• The recirculation ratio RCs, RCr and bypass ratio BPR.

Note:  This document includes the definition of measuring bypass ratio but excludes the definition of levels of bypass ratio.

Who is BS EN IEC 62610‑6 for?

 BS EN IEC 62610‑6 on Mechanical structures for electrical and electronic equipment is useful for:

• Manufacturer of electronic devices
• Manufacturer of safety storage cabinets
• Hospitals
• Electrical Engineers

Why should you use BS EN IEC 62610‑6?

BS EN IEC 62610‑6 will help you in measuring the recirculation ratios (RC) and the

bypass ratio (BP) of the airflow in a cabinet, which helps in determining the performance level of recirculation of indoor cabinets.

BS EN IEC 62610‑6 helps in utilizing the heat exchanger and an air conditioner in an outdoor cabinet that results in knowing the airflow is appropriate or not. 

With the help of BS EN IEC 62610‑6, you will be able to prevent high-temperature problems arising in electronic equipment by using air recirculation and bypass airflow in indoor cabinets. BS EN IEC 62610‑6 helps in determining the airflow in cabinets and helps in assembling these cabinets with subtracting and chassis-based equipment.
