We are currently carrying out the chemical cleaning and flushing of a chilled water piping system associated with a Carrier Chiller installation and require third-party laboratory testing of the flushing water sample to verify satisfactory completion of the chemical cleaning process.
The cleaning process was performed using the following chemicals:
• TIG Group 104L – Acidic Cleaning Chemical
• TIG Group 112L – Alkaline Cleaning / Neutralizing Chemical
In this regard, kindly provide your quotation for laboratory testing and analysis of the submitted water sample covering the following parameters:
| Parameter | Acceptance Criteria |
| Appearance | Clear, Colorless, Odorless |
| pH | 7.0 – 8.5 |
| Conductivity | < 450 µS/cm |
| Suspended Solids (TSS) | < 5 mg/L |
| Turbidity | < 10 NTU |
| Total Iron (Fe) | < 0.5 mg/L (ppm) |
| Total Hardness | 50 – 100 ppm |
| Chloride (Cl-) | Report Value |
| Sulphate (SO₄²⁻) | Report Value |
| Total Dissolved Solids (TDS) | Report Value |
| Residual Acidity / Alkalinity | Report Value |
| Copper (Cu) | Report Value |
| Biological Activity / Bacteria Count (if available) | Report Value |
Additionally, we request that the test report include a clear statement indicating that:
- The sample meets the requirements for satisfactory completion of chemical cleaning and flushing.
- The system has been adequately neutralized following acidic and alkaline cleaning.
Kindly provide your quotation, sample volume requirements, turnaround time for testing, and any specific sample collection or preservation requirements.
