Note: The representative sample should be carefully designed so that it can reveal similar failure mechanisms as the full-size one, and the fabrication of the full-size ones.

See table 7 See table 7 8 Cleaning and recovery After the ammonia test all samples must be washed to remove the adherent ammonia using running tap water (not artificially pressurized) for a maximum time of 5 minutes per square meter of area of the sample. Once the washing is finished distilled or demineralized water must be used to rinse the samples, followed by complete drying at room temperature. Note: The temperature of the water used for washing shall not exceed 35. During cleaning or drying the use of cloths, gauzes or any other woven material must be avoided and no scraping is allowed. 9 Final Measurements
