The conductometric method used for monitoring track etching processes in polymeric materials was in- troduced. Considering the improper application of some assumptions in data analysis
models were proposed and nu- merical calculations were conducted by taking into account of track break-through time distribution
pore shape as well as etchant conductivity inside small pores. The analysis has provided new information related to latent track structure
etchant conductivity inside pores and the influence of track etching rate ratio on the pore shape.
