Scope Scope*1.1 This specification defines requirements for the data used in the tracking and traceability base-62 encoding system and theformat of the resultant code to characterize various components used in fuel gas piping systems.1.2 The final output of this spec
4、ification is a 16 digit alpha-numeric code that defines a standardized approach or methodologyfor encoding certain characteristics of components that have been established based on consensus recommendations from therespective stakeholder group members. The means of marking or affixing the code to th
