Standards and professional practice
Quantitative testing remains separate from visual observation
- ASHRAE Standard 111-2024 purpose and scope: HVAC measurement, testing, adjusting, balancing, evaluation and reporting.
- NEBB — Testing, Adjusting and Balancing: systematic measurement and adjustment of HVAC performance.
- ISO 14644-3:2019: cleanroom and clean-zone test methods.
- FDA aseptic-processing guidance: context for airflow visualization in sterile processing.
- FDA 2026 warning-letter example: dynamic studies should represent actual equipment, materials and interventions.
Safety references
Fog medium and exposure require review
- NIOSH Health Hazard Evaluation: theatrical smoke: minimize exposure, avoid direct concentrated release and use manufacturer-approved fluids.
- NIOSH smoke-simulant case study: high exposure to mineral-oil mist can create serious respiratory hazards.
Claim tiers
How the site uses evidence
| Tier | Evidence | Treatment |
|---|---|---|
| Current product truth | Active AP product page plus internal confirmation. | Specific but subject to quotation/protocol reconfirmation. |
| Legacy manufacturer record | Historic AP pages or manuals. | Labeled archival; conflicts remain visible. |
| Formal standard / regulator | ISO, FDA, ASHRAE, NEBB, NIOSH. | Summarized within scope; never converted into product certification. |
| Engineering recommendation | Reasoned application guidance. | Presented as planning advice, not historic product fact. |
| Unknown or conflicting | Insufficient or inconsistent evidence. | Qualified, routed for review or omitted. |
Frequently asked questions
Questions this page should settle
Why are some product specifications qualified?
Applied Physics pages and product configurations can change. Current values should be reconfirmed before quotation, purchase or protocol use.
Does linking a standard mean the fogger complies with it?
No. The standard governs a method, facility, system or evidence. Product selection is only one part of compliance.
