while being aware of different usages of common terms

It helps them with the selection of test pieces

BS EN IEC 62631-3-4 covers the procedures for the determination of insulation resistance and volume resistivity of insulating materials by applying DC-voltage and temperatures up to 800 °C

The tests described are also applicable to products that have received a preservative treatment

ISO 15186 3 is the third part of the multiple series that specifies a sound intensity method to determine the sound reduction index and the element normalized level difference of building elements at low frequencies. This method has significantly better reproducibility in a typical test facility than those of ISO 140 3, ISO 140 10, and ISO 15186 1.
