Significance and Use4.1 This practice provides requirements for the handling,transportation, and storage of HFC-23 encountered in distribu-tion through both commercial and military channels. It isintended to ensure that HFC-23 is handled, transported, andst
10、ored in such a way its physical property values are notdegraded. Transport may be by various means, such as, but notlimited to, highway, rail, water, and air.5.
