CORROSIVE GASES: Small concentrations, serious consequences

EU standard 2002/95/EC, or RoHS (Restriction of the use of certain Hazardous Substances in electrical and electronic equipment), which was implemented in July 2006, restricts the use of hazardous substances in the manufacture of electrical and/or electronic equipment.

One of the banned substances is lead (Pb), which is used for soldering circuit boards and other components in hard disks, servers, etc.

To make equipment that is free from lead, the Pb has been replaced by materials which are much more sensitive to the corrosive agents in the air. Consequently, the monitoring of air quality in data centres is a key factor in preventing faults in infrastructures.

According to the ISA 71.04.1985 standard (Environmental Conditions for Process Measurement and Control Systems: Airborne Contaminants), there is a very simple quantitative method for determining the corrosiveness of air in data centres: corrosion coupons (copper and silver), which, after a period of exposure and subsequent analysis, allow the corrosiveness of the atmosphere to be determined, according to the following classification:

In response to the growing concern in the market about preserving the quality of air in data centres, BIOCONSERVACION offers an effective, comprehensive solution for each case.

BIOCONSERVACION has its own laboratory, in which coupons can be analysed to determine the characteristics of the atmosphere.

Subsequently, to ensure the most effective solution, our technical department evaluates other factors in the work area: sealing, entry and exit of personnel, generation of contaminants in the work area, temperature, humidity, etc.

Finally, taking all the parameters into account, BIOCONSERVACION recommends the best solution for filtering the air, using pressurised systems or combined pressure-recycling systems.
