Special gas storage period specification1 ScopeThis standard specifies the various specialty gases should reach at least the storage period. This standard applies to the use of appropriate container filling, after analysis of the special store spare gas, also applies to the special gas production plants and for Gas suppliers provided. In this standard, the storage period is from the point of view of quality. This standard does not address the extended storage-related security Wide issues.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 The remaining amount residuallevel Left in the container to the quality or quantity of surplus product manometer. This amount should be minimized in order to minimize the gas filling the last high Influence of impurity content production process. 2.2 Storage period shelflife From the time the analysis is complete, the supplier of gas quality guarantee period. Within this period, should ensure that an accurate analysis of impurities over Technical indicators remain at or below the upper level of a particular gas regulations. 2.3 Blood stem liquiddry All liquefied gas liquid runs out.3 Requirements3.1 Special factors affect gas storage period 3.1.1 Thermal stability of gas. 3.1.2 quality container and valves ---material selection; --- Tightness. Stability and coexistence of different substances 3.1.3 gas --- Gas and impurities; --- Gas and packaging materials. 3.1.4 Analysis and filling operations. 3.1.5 Transport and storage conditions. 3.1.6 the amount of container products. 3.1.7 valve tightness of the gas reservoir is to determine the critical factor, particularly for the low pressure gas. In order to improve the gas with different composition Coexistence stability quality, should first purified gas to a certain extent, so that the impurities contained no change over time, should also choose the right Packaging Materials. Before the filling of the inner surface of the container the chemical, physical, or passivation treatment to be effective in reducing the reaction time and with the continuation of production Health impact. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 26571-2011_English be delivered?Answer: Upon your order, we will start to translate GB/T 26571-2011_English as soon as possible, and keep you informed of the progress.
