BUTLER, IN 46721

INTRODUCTION

This report gives the results of Sound Transmission Loss tests and the determination of theSound Transmission Class on seven doors. The doors were selected and supplied by the clientand received at the laboratories on November 27, 2001. They appeared to be in a new, unusedcondition.

AUTHORIZATION

Purchase Order No. 20004575 from Therma Tru Doors.

TEST METHOD

-" Each specimen was tested in accordance with the American Society for Testing and Materialsdesignation ASTM E90-99, "Standard Test Method for Laboratory Measurement of AirborneSound Transmission Loss of Building Partitions" and classified in accordance with the AmericanSociety for Testing and Mater~als designation ASTM E413-87 (Re-approved 1999, "Classificationfor Rating Sound Insulation" and ASTM Standard E1332-90 (Re-approved 1998) entitled,"Standard Classification for Determination of Outdoor-Indoor Transmission Class".

,,::

An Independent organization testing for safety, performance, and certification.

All services undertaken subject to the following general policy: Reports are submitted for exclusive use of the clien1-sto whom they are addressed. Their significance is subject to the adequacy and representative character of the samplesand to the comprehensiveness of the tests, examinations or surveys made. No quotations from reports or use of ITS'name is permitted except as expressly authorized by ITS in writing.

GENERAL

The sound-insulating property of a partition element is expressed in terms of the soundtransmission loss. The procedure for determining this quantity is to mount (and perimeter seal)the test specimen as a partition between two reverberation rooms. Sound is introduced in oneof the rooms (the source room) and measurements are made of the noise reduction betweensource (10,000 cu. ft.) room and receiving room (16,640 cu.ft.). The rooms are so arranged andconstructed that the only significant sound transmission between them is through the testspecimen.

~

0:

The test opening is constructed such that it is approximately one inch larger in size than the testspecimen. The specimen is placed in the test opening on a half-inch bead of "DUX-SEAL", adense, non-hardening, clay-like material, to isolate it from the supporting base. The spacebetween the test specimen and the wall,opening is sealed on both sides employing the samesealing material. The test specimen is perimeter sealed (both sides) with the same materialbetween the two reverberation rooms.

The purpose of the Sound Transmission Class (STC) is to provide a single figure rating that can.be used for comparing the sound-insulating properties of partition elements used for generalbuildingdesign purposes. The higher the rating (STC)the greater the sound insulating propertiesof the partition.

The purpose of the Outdoor-Indoor Transmission (OITC) is to provide a single number ratingthatcan be used for comparing building facade designs, including walls, doors, windows andcombinationsthereof. This rating is designedto correlatewith subjective impressionsof the abilityof building elements to reduce the overall loudness of ground and air transportation noise. It isintended to be used as a rank ordering device.

DESCRIPTION OF TEST SPECIMENS
