Toxicity Index (CIT) Test ApparatusApplicable to the toxicity index test of non-metallic materials of halogen-free, low-smoke, low-toxic wires and cables or optical cables The test is carried out in two parts: - First, a preliminary qualitative analysis is carried out to determine whether it contains nitrogen and sulfur?
- If it is determined that nitrogen and sulfur are present, a quantitative analysis of SO2, NOX and HCN should be carried out. If it is confirmed that there is no nitrogen and sulfur, a quantitative analysis of SO2, NOX and HCN can be omitted.
