For non-flammable gas, the chemical formula contains three or more atoms, should adopt the coefficient Kk = 1.5" Is "Note. For non-flammable gases and non-oxidizing gas, chemical formula contains three or more atoms of the conversion factor, should Kk = 1.5. Some non-flammable partial halogenated hydrocarbons, such as coolant R134a, in the presence of flammable gas, it is possible to empty Gas and nitrogen partial response. For containing non-flammable, partially halogenated hydrocarbons, and the mixture of flammable gases, such as If the combustible fraction more than 0.25%, shall not apply this method of calculation. These data may be based in the gasification plant and trial experience Test data, a conservative estimate "; --- Amend 6.2.3.1 in the "calculation method according to ISO 10156.1996 provisions of Article 5.3" for the "calculation method according to ISO 10156.

Pyrex reaction tube should be 4.4 (thickness 5mm) made of an inner diameter of at least 50mm, a length of at least 300mm. Anti During the test The tube should be kept clean to avoid contamination of impurities, especially water. 4.5 reaction tube and a flow meter should be sufficient to cover in order to protect the test in the explosions may occur. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1828.12-2019_English be delivered?Answer: Upon your order, we will start to translate SN/T 1828.12-2019_English as soon as possible, and keep you informed of the progress.
