sample submission guidelines
Here you can find the best practices for collecting and submitting samples of aircraft deicing fluid.
To ensure the continued validity of the semi-annual lab analysis certification, we strongly encourage you to follow these instructions to send samples in a timely and correct manner.
sample collection
- Fully flush nozzles, hoses, sampling ports, before collecting the sample. Nozzles may require flushing with as much as100 liters of fluid.
- For Type II/IV fluids, ensure the nozzles and va!ves are fully open when sampling. Partially-open valves and nozzles can cause shearing of fluid
- Use a dry, clean sampler and sample bottle when collecting the sample.
sample verification
- Check the appearance of the sample.
- Type I fluids should be transparent and orange in color.
- Type IV fluids should be semi-transparent, viscous and yellow/straw in color.
- Type IV fluids should be semi-transparent, viscous and green in color.
- For Type I and Type II/IV fluids, test the Refractive Index of the sample.
- Type I concentrate = 1.4165 – 1.4195 (100%)
- Type II/IV concentrate = 1.3900 – 1.3930 (100%)
- Type II/IV dilute 75/25 = 1.3768 – 1.3809
- Type II/IV dilute 50/50 = 1.3622 – 1.3663
- If the sample does not meet any of the above criteria for appearance or refractive index, flush additional fluid and resample.
sample submission
- Fill in both sides of the label document
- Your reference#ID will be transferred exactly as written to the lab report. Be sure to enter this information exactly as you require it to appear.
- You can use the labels on the left side for your own records.
- Clean the outside of the sample bottle and wipe hands clean before affixing the right part of the sample label. Use of a pencil is recommended. Deicing fluids will smear most inks.
- Tightly close sample bottles and wrap lid with electrical tape.
- Put the back of the label page in the shipping box.
- You can use the bottom shipping label on the outside of the box
