Scope

Scope: This document specifies the reagents or materials, instruments and equipment, sample requirements, test methods, and test procedures for the precipitation test of powdered flame retardants in thermoplastic plastics. This document is applicable to the precipitation test of powdered flame retardants in thermoplastic plastics. Main technical content: 7.1 Test methods 7.1.1 Constant-temperature precipitation method: Place the black sample bar from Section 6.3 at room temperature for 6 months. Record the appearance of the sample bar every 5 days to observe whether the flame retardant has precipitated on the surface of the sample bar. 7.1.2 Accelerated precipitation method: Place the black sample bar from Section 6.3 in a constant-temperature and humidity chamber with a temperature set at (85±2)℃ and a humidity set at (85±2)% RH. Record the appearance of the sample bar daily to observe whether the flame retardant has precipitated on the surface of the sample bar, and continue recording for 7 days. 7.1.3 Boiling precipitation method: Place the black sample bar from Section 6.3 in a 500 mL beaker, add 400 mL of distilled water to the beaker, and seal the beaker with cling film. Place the beaker in a constant-temperature water bath with a water temperature set at (70±2)℃. Replace the water once daily and observe whether the water in the beaker has become turbid. Continue recording for 7 days.
