study scientifically not necessary / other information available
Justification for data waiving:

Description of key information

An explosiveness study with the substance tert-butyl peroxypivalate (TBPPI) was waived as the substance is classified as Organic Peroxide Type C and not as Organic Peroxide Type B.

Key value for chemical safety assessment

non explosive

Additional information

Tert-butyl peroxypivalate (TBPPI) has no explosive properties because it is not classified as Organic Peroxide Type B (reference CLP regulations and UN Recommendations on the Transport of Dangerous Goods, 17th revised edition, Section See also ECHA guidance on the application of the CLP criteria, section 2.14. TBPPI is classified as organic peroxide Type C. The classification of organic peroxides into one of the seven categories of “Types A to G” is given in decision logic Figure 2.15.1 of CLP, based on the test series A to H, as described in the Part II of the UN-MTC. See endpoint 4.13 Flammability.

Justification for classification or non-classification

According to Regulation (EC) No 1272/2008 (CLP) TBPPI is classified as Organic Peroxide Type C with H242 (heating may cause a fire).
