The World Health Organization (WHO) and other regulatory agencies provide guidelines for differential pressure in various industries:

WHO Guidelines:

1. WHO Guidelines for Pharmaceutical Industry (2011)
– Differential pressure: 10-15 Pa (0.1-1.5 mbar) for clean rooms
2. WHO Guidelines for Biomedical Equipment (2011)
– Differential pressure: 5-10 Pa (0.05-1 mbar) for operating rooms
3. WHO Guidelines for Healthcare Facilities (2018)
– Differential pressure: 5-10 Pa (0.05-1 mbar) for isolation rooms

International Standards:

1. ISO 14644-3 (Cleanrooms and associated controlled environments)
– Differential pressure: 10-15 Pa (0.1-1.5 mbar)
2. ISO 13485 (Medical devices – Quality management systems)
– Differential pressure: Not specified, but referenced in ISO 14644-3
3. EN 13779 (Ventilation systems for non-residential buildings)
– Differential pressure: 5-10 Pa (0.05-1 mbar)

Industry-Specific Standards:

1. ASHRAE 170 (Healthcare Facilities)
– Differential pressure: 5-10 Pa (0.05-1 mbar)
2. USP 797 (Pharmaceutical Compounding)

3. EU GMP Annex 1 (Manufacture of Sterile Medicinal Products)
– Differential pressure: 10-15 Pa (0.1-1.5 mbar)

Regulatory Agencies:

1. FDA (US Food and Drug Administration)
2. EMA (European Medicines Agency)
3. MHRA (Medicines and Healthcare products Regulatory Agency, UK)

Please note:

– Differential pressure standards may vary depending on specific industry, application, or region.
– Consult relevant regulations and guidelines for your specific industry.
– Ensure compliance with local laws and regulations.
