SAAF™ Reactivity Monitoring Coupons (RMC)


SAAF™ Reactivity Monitoring Coupons (RMC)

  • Investigative tool to gauge gas-phase filter performance
  • Ideal for site assessment reports related to air reactivity
  • Qualifies the presence or absence of gas types (sulphur compounds, chlorine compounds, compounds that form oxide films, and unknowns)
  • Quantifies reactivity of environment per ISA-71.04-2013 and related coupon standards
  • Available in light-duty and heavy-duty versions to suit the application contamination severity

Protecting Your Investment

Corrosion due to air reactivity can have costly consequences. In refining, pulp and paper mills, tyre manufacturing, and other process industries, the most significant consequence of electronic equipment corrosion and failure is downtime and lost production. In other industries, corrosion of server components means data centre downtime. Transactions stop, software applications for logistics cannot run, and data cannot be stored. For areas using compressors, reactive air can lead to more frequent maintenance schedules, process downtime, and eventually shortened compressor life.


SAAF Reactivity Monitoring Coupons provide information on average air reactivity over 30 days. This data helps clients evaluate area or room conditions in relation to air reactivity, and take any needed action to protect their electronics, equipment and processes.


Data Interpretation and Reporting

The SAAF Laboratory produces an application-specific report to summarise the data. This report provides photographs of new coupons and the exposed coupons for visual reference. It summarises the resulting environment classification, total corrosion formed on the coupons during installation, and individual corrosion film information, to differentiate between types of contaminants.

Comparing Data to Applicable Industry Standards

Industry standards exist for the protection of legacy electronics in process control rooms (ISA 71.04-1985), and for ROHS-compliant electronics used in control rooms, data centres, tyre manufacturing facilities, and other areas (ASHRAE TC 9.9 Guideline & ISA 71.04-2013). Compressor performance in archives and museums has also been correlated to reactivity monitoring results. Data from SAAFShield Technology can be directly related to these standards to evaluate the condition of spaces housing critical electronics, compressors or archival materials.

Measuring Environmental Reactivity

RMCs determine environment reactivity through exposure in the environment and subsequent lab analysis. This technology is used to investigate the condition of control rooms or other protected environments housing electronic equipment in industrial facilities such as pulp and paper mills, petrochemical refineries, and chemical plants. RMCs are also used to investigate the condition of facilities storing sensitive materials such as museums and archives, data centers, and microelectronic production or storage areas. Additionally, mechanical equipment like compressors can be affected by reactive gases in the air and can be evaluated with RMCs. Various standards and classification schemes are in existence which correlate corrosion film amounts to reactivity classifications.

Where to Use Reactivity Monitoring Coupons (RMCs)

Typical on-site test locations for RMCs include protected or critical spaces near critical electronic equipment or sensitive materials, upstream and downstream of gas-phase filters, and outdoor air intakes.  In addition to quantifying the reactivity of a particular environment, RMCs can be used as investigative tools to gauge the performance of gas-phase filter systems with respect to removal of gas types and the media replacement condition.
