This guidance augments the basic guidance given in Clause 6.5.5 of EN ISO 14713 Part 2: 2009. Liquid metal assisted cracking (LMAC), or liquid metal embrittlement (LME), occurs when a combination of steel characteristics, fabrication detailing and galvanizing processing variables create conditions for brittle cracking of a steel article during galvanizing. Such a combination of factors rarely occurs in practice. For fabrications that might be susceptible to LMAC, it is recommended to follow the guidance contained in this document.
