What is BS EN ISO 14698-1:2015?

BS EN ISO 14698-1:2015 is an international standard that specifies the requirements and guidance for

biocontamination control in cleanrooms and associated controlled environments. The standard provides a

framework for designing, implementing, and monitoring control measures to minimize the risk of


Cleanrooms are highly controlled environments used in various industries such as pharmaceuticals,

healthcare, electronics, and food production. They are designed to maintain specific levels of cleanliness

to ensure the quality and safety of products or processes. However, the presence of microorganisms in

cleanrooms can pose serious risks, especially in sensitive industries like pharmaceuticals.

BS EN ISO 14698-1:2015 addresses the need for a standardized approach to biocontamination control. It

outlines the principles and practices for assessing and controlling biocontamination. The standard covers

a wide range of topics including risk assessment, control strategies, monitoring methods, and validation


Risk Assessment in Biocontamination Control

Risk assessment plays a crucial role in biocontamination control. It involves identifying potential sources

of contamination, evaluating their impact, and implementing appropriate control measures. BS EN ISO

14698-1:2015 provides a systematic approach to conducting risk assessments in cleanroom environments.

The standard emphasizes the importance of understanding the sources, distribution, and behavior of

microorganisms. This knowledge enables organizations to develop effective control strategies tailored to

their specific needs. Additionally, risk assessment helps determine the frequency and type of monitoring

activities required to detect and prevent biocontamination.

By following the guidelines outlined in BS EN ISO 14698-1:2015, organizations can better identify risks and

implement control measures that minimize the impact of biocontamination on product quality and safety.

Control Strategies and Monitoring Methods

BS EN ISO 14698-1:2015 provides guidance on selecting and implementing control strategies to prevent or

minimize biocontamination. These strategies may include air handling systems, disinfection procedures,

and personal protective equipment. The standard emphasizes the importance of a holistic approach to

control, considering factors such as design, operation, and maintenance.

In addition to control strategies, the standard also outlines various monitoring methods to assess the

effectiveness of biocontamination control measures. These methods include viable and non-viable particle

monitoring, surface swabbing, and air sampling. Regular monitoring helps ensure that cleanrooms maintain

their desired cleanliness levels and allows for timely identification and correction of potential issues.

By implementing appropriate control strategies and utilizing effective monitoring methods, organizations

can maintain cleanroom environments that meet the requirements of BS EN ISO 14698-1:2015.

Validation Techniques and Compliance

Validation is an essential component of biocontamination control. It involves verifying that the control

measures and procedures implemented in a cleanroom are effective in preventing or minimizing

biocontamination. BS EN ISO 14698-1:2015 provides guidance on validation techniques and acceptance


The standard highlights the importance of regular validation activities to ensure ongoing compliance with

the requirements. It defines the parameters to be evaluated during validation, such as particle counts,

microbial levels, and airflow measurements. Additionally, it specifies the frequency and extent of

validation required based on the specific cleanroom classification and usage.

By adhering to the validation guidelines outlined in BS EN ISO 14698-1:2015, organizations can ensure that

their cleanrooms consistently meet the necessary standards for biocontamination control.
