3 Terms and Definitions

The United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations ·" (hereinafter referred to as "Model Regulations") and the following definition of terms and definitions Meaning applies to this document. 3.1 Self-reactive substances self-reactivesubstances Even without oxygen (air) is also prone to thermally unstable substances strongly exothermic decomposition, in the "Model Regulations" hazardous category 4.1 Self-reactive substances. The following materials should not be considered 4.1 self-reactive substances. --- according to the standard of Class 1 they are explosives; 5.1 --- The procedure of classification, which are oxidizing substances, but mixtures of oxidizing materials, such as combustible organic substances contained up To 5.0% or more, it should go through the classification procedure defined GB 21178; According to standard 5.2 --- they are organic peroxides; --- thermal decomposition of less than 300kJ/kg; --- which SADT 50kg package is larger than 75 ℃. 3.2 SADT self-acceleratingdecompositiontemperature (SADT) Packaged material self-accelerating decomposition of the lowest ambient temperature may occur. Category 4 4.1 self-reactive substances classification The degree of self-reactive substances according to their risk of A to G into seven types, see GB 21178. Since the packaging material is only suitable reaction Wherein BF for self-reactive substances. a) A self-reactive substances, any substance, such as to detonate or deflagrate rapidly transport package. Specific carried out in accordance with GB 21178 Determination, it is determined that A, shall be prohibited mounted in the container transported under the provisions of this Standard. b) B self-reactive substances, any substance having explosive properties, such as rapid deflagration neither detonates nor transport package but the The package may undergo a thermal explosion, it should be labeled "EXPLOSIVE" subsidiary risk label. Such materials in containers number The amount of up to 25kg, but in order to preclude detonation or rapid deflagration in the package and should limit the maximum amount in addition to the lower of outer. GB 21178 determines the specific basis, determined to B. c) C self-reactive substances, any substance having explosive properties, such as (up to 50kg) in a fast transport can not detonate or package Thermally speed deflagration or explosion, not "EXPLOSIVE" secondary risk label transport. GB 21178 determines the specific basis, Determined to C. d) D self-reactive substances, any substance, such as in laboratory testing. 1) partially detonation, deflagration not quickly, does not exhibit any dramatic effect when heated under confinement; or 2) does not detonate, a slow deflagration, does not exhibit any dramatic effect when heated under confinement; or 3) does not detonate or deflagrate exhibit moderate effect when heated in a closed condition; Acceptable mounted net does not exceed 50kg packages transported. GB 21178 determines the specific basis, determined as D. When e) E self-reactive substances, any substance, such as in laboratory testing, neither detonates deflagration never heated under confinement Exhibit low or no effect, not exceeding an acceptable means 400kg/450L packages transported, into specific basis GB 21178 Line determination, it is determined that E. f) F self-reactive substances, any substance, such as in laboratory testing, not only in cavitation and never detonation knocking state, closed Under conditions show weak or no effect only upon heating, weak or non-explosive and explosive, it may be considered for IBC or tank Transport of, in particular according to GB 21178 determines, determined is F; portable tank may be employed and the neutral bulk container transport. g) G self-reactive substances, any substance, such as in laboratory testing, both not detonate never empty state of knocking, the closing Show no effect when heated under a condition, and no explosive power, should be exempted from 4.1 classified as self-reactive substance, but the formulation should Is thermally stable (self accelerating decomposition temperature 50kg package 60 ℃ ~ 75 ℃), any diluent should follow the "Model Regulations" in Required, if the formulation is not thermally stable, or with a compatible diluent having a boiling point of less than 150 ℃ desensitization, the formulation should be set as F-type From the reaction of liquid/solid.
