TBC and Legionella Testing Certified Labs

Posted by: Chemist Posted on: July 23, 2026

TBC (Total Bacterial Count) and Legionella testing are two different types of microbiological water tests, each serving a different purpose.

1. TBC (Total Bacterial Count)

Also called:

Total Viable Count (TVC)
Heterotrophic Plate Count (HPC)

Purpose:
Measures the total number of viable bacteria present in a water sample. It does not identify specific bacteria or indicate whether they are harmful.

Common uses:

Drinking water quality monitoring
Process water testing
Cooling towers
Hospital water systems
Food and beverage industries

Typical method:

Plate Count Agar (PCA) or similar media
Incubation at specified temperatures (commonly 22°C and/or 36–37°C) for defined periods
Results reported as CFU/mL (Colony Forming Units per milliliter)

Interpretation:

Low counts generally indicate good microbiological quality.
High counts may suggest poor sanitation, biofilm formation, or stagnation, but they do not necessarily indicate the presence of pathogens.

2. Legionella Testing

Purpose:
Detects and quantifies bacteria of the genus Legionella, particularly Legionella pneumophila, which can cause Legionnaires’ disease.

Common sources tested:

Cooling towers
Hot and cold water systems
Hospitals
Hotels
Spa pools
Decorative fountains

Testing methods:

Method	Detects	Time to Result
Culture (ISO 11731)	Live Legionella	7–10 days
qPCR	Legionella DNA	Few hours to 1 day
Rapid antigen tests	Specific targets	Minutes to hours (limited use)

Results:

Reported as CFU/L for culture methods.
qPCR results are typically reported as genome copies per liter or similar molecular units, depending on the laboratory.

Comparison

Feature	TBC	Legionella
Measures	Total viable bacteria	Specific Legionella bacteria
Specificity	Non-specific	Highly specific
Indicates pathogens?	No	Yes
Typical unit	CFU/mL	CFU/L
Main purpose	General water hygiene	Public health risk assessment

Why both tests are often performed

A water system can have:

Low TBC but detectable Legionella, or
High TBC but no Legionella.

Because of this, TBC cannot be used to confirm or rule out the presence of Legionella. For systems with a risk of aerosol generation (such as cooling towers, healthcare facilities, hotels, and large building water systems), Legionella testing should be performed separately as part of a water safety management program.

If you’re working with a particular standard (such as ISO, WHO guidance, ASHRAE, or local regulations), the testing frequency and action limits may differ. I can also explain the relevant requirements for those standards.

HVAC Performance and Safety Testing in Doha, Qatar

Posted by: Chemist Posted on: July 18, 2026 displacement ventilation diffusers performance testing

Enquiry:

Aerodynamic and acoustic performance testing on our new plastic under-seat displacement ventilation diffusers

We are seeking an accredited third-party laboratory to perform aerodynamic and acoustic performance testing on our new plastic under-seat displacement ventilation diffusers. These components will be deployed in a major open-air stadium project.

We require certification in strict accordance with ANSI/ASHRAE Standard 70 (or BS EN 12238 / BS EN 12239 equivalent metrics).

Required Testing Scope

The laboratory testing must evaluate and chart the following specific schedule parameters:

Design Air Flow Rate: Performance mapping across a range of volumes measured in Liters per Second (L/S).
Nozzle Discharge Velocity: Centerline velocity measurements measured in Meters per Second (M/S).
Acoustic Performance: Noise Criteria (NC) Level rating derived from octaval sound power testing in a reverberation room.
Maximum Pressure Drop: Resistance measurements across the assembly measured in Pascals (Pa).

Product Spec Summary

Component Type: Floor / Riser Mounted Under-Seat Displacement Diffuser
Material Composition: Injection-molded plastic polymer (UV stabilized)
Sample Units Available: [Insert number, e.g., 3] production-ready samples can be shipped immediately.

Request for Quotation (RFQ) Requirements

Please reply with your introductory proposal including:

Cost estimate for the full performance test and final stamped report generation.
Standard lead time from sample receipt to official data delivery.
Accreditations held by your facility (e.g., ISO 17025, ILAC-MRA).

If your facility also provides accelerated outdoor weathering / UV degradation testing under ISO 4892, please list that as an optional line item. We look forward to your prompt response.
