This part of ISO 17201 specifies a method to determine the acoustic source energy of the muzzle blast for calibres of less than 20 mm or explosive charges of less than 50 g TNT equivalent. It is applicable at distances where peak pressures less than 1 kPa (equivalent to a peak sound pressure level of 154 dB) are observed. The source energy, directivity of the source and their spectral structure determined by this procedure can be used as input data to sound propagation programmes, enabling prediction of shooting noise in the neighbourhood of shooting ranges. Additionally, the data can be used to compare sound emission from different types of guns or different types of ammunition used with the same gun.

This part of ISO 17201 is applicable to guns used in civil shooting ranges but it can also be applied to military guns. It is not applicable to the assessment of hearing damage or sound levels in the non-linear region.

This International Standard specifies how screens, furniture and single objects intended for interior use will be assessed with regard to sound absorption. The International Standard also specifies the evaluation of sound attenuation for floor screens. It also specifies under which circumstances various interior products for offices, schools and other public spaces are considered as plane absorbers or as discrete single objects. A product considered as a single object and intended for interior use, is measured according to ISO 354, and evaluated by its equivalent sound absorption area or object sound absorption coefficient in octave bands. This International Standard defines interior products and single objects and it comprises additional information regarding measurements and assessment of single objects.

The sound absorption as specified in this International Standard can be used a) to calculate reverberation time characteristics in rooms;

b) to calculate room acoustic parameters using ray tracing software.

This European Standard specifies requirements for machine-made (woven, tufted, knitted, needled, flocked, bonded, hand-tufted) rugs and runners, including a classification according to use intensity and luxury.

This European Standard is not applicable to hand-knotted rugs, to barrier mats or to bathroom rugs.
