10 Test report
Annex A (normative) - A-weighting and C-weighting
correction value
Annex B (normative) - Operating conditions and operating
cycles of equipment to be tested for measuring
the maximum sound pressure level and the equivalent
continuous sound pressure level
Annex 1 (informative) - Measurement method of the sound
pressure level of measurement points installed at
the corner positions and the reverberant field
positions
Annex 2 (normative) - Measurement method of the reverberation
time and measurement method of the equivalent sound
absorption area level using the reference sound source
Annex 3 (informative) - Comparison table between JIS and
corresponding International Standard
Describes methods for measuring the sound pressure level from water equipment in the room installed to building structures.
