- Conclusions:
- In conclusion, the relative density of diphosphoric acid, compound with 1,3,5-triazine-2,4,6-triamine (1:2) was determined to be 1.813.
Reference
The relative density of test substance was determined using the gas comparison method at a temperature of 20 °C.
The determination of the relative density was performed by three-fold measurements of two independent test item samples. The individual readings are summarised in Table 1.
The density of test substance was determined to be 1.813 g/cm³ (= 1813 kg/m³) at 20 °C.

Additional information
The relative density of diphosphoric acid, compound with 1,3,5-triazine-2,4,6-triamine (1:2) (CAS 13518-93-9, EC236-860-0) was determined according to OECD Guideline 109 and GLP using the gas comparison method at a temperature of 20 °C (Wagner-Rivas V, 2017).
The determination of the relative density was performed by three-fold measurements of two independent test item samples. The density of diphosphoric acid, compound with 1,3,5-triazine-2,4,6-triamine (1:2) (CAS 13518-93-9, EC236-860-0) was determined to be 1.813 g/cm³ (= 1813 kg/m³) at 20 °C.
