what is the meaning of 40/20 src..

Answer / Sanjeev Singh Tomar

In civil engineering, '40/20 src' often refers to a fire resistance rating system. The numbers indicate the hours of fire resistance for a given material. In this case, '40' means the material can withstand fire for 40 minutes, and '20 src' indicates it was tested according to a specific standard (BS 476 Part 20 in the UK). However, without more context, this is just an educated guess.
