This European Standard specifies information additional to EN ISO 10140 1 necessary to carry out efficiently and under standardized conditions the determination of the sound reduction index of drywall systems of plasterboard with steel studs according to EN ISO 10140 2 “Acoustics — Laboratory measurement of sound insulation of -building elements — Part 2: Measurement of airborne sound insulation”. Observe that all demands in EN ISO 10140 2 should still be fulfilled. In order to decrease the uncertainty, it specifies:-additional guidelines for testing drywall systems of plasterboard with steel studs;and-a method to validate laboratory by using two reference test partitions.The results obtained are used to convert frequency-dependent sound reduction index into single number ratings, according to EN ISO 717 1. These performances can be used to compare different products, or, and to express a requirement, or, and as input into estimation methods, such as EN 12354 1.
