Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
Amendment 1 to IS0 354:1985 was prepared by Technical Committee
ISOTTC 43, Acoustics, Subcommittee SC 2, Building acoustics.
Annex D will form an integral part of IS0 354.

Acoustics - Measurement of sound absorption in a reverberation
room
AMENDMENT 1: Test specimen mountings for sound absorption tests
Page 10
Add the following annex.
Annex D
(normative)
Test specimen mountings for sound absorption tests
D.l General

The sound absorption properties of a material depend on how that material is mounted during a test. This annex

specifies several different standard mountings for sound absorption tests. Normally a test specimen is tested using

only one of the specified mountings.

Designations for type E and type G mountings include a numerical suffix, for example E-200 or G-100. The suffix is

equal to a distance characteristic of the mounting, in millimetres, rounded off to the nearest 5 mm.

NOTE - Where applicable, the designations used for each type of mounting have been chosen to match those used in a

standard that already existed when this annex was written: ASTM E 795, Standard Practices for Mounting lest Specimens

During Sound Absorption Tests.
D.2 Type A mounting

The test specimen shall be mounted or placed directly against a room surface, such as the floor of the reverberation

room. Measure plane elements (e.g. partition walls) lying on the floor. If an adhesive or mechanical fastening

system is required to mount the test specimen, it shall
