Standard Specification for Reference Specimen for Sound Transmission Loss

ABSTRACT
This specification describes the construction and installation of standard reference specimens for quality control of laboratory sound transmission loss measurements. The reference specimen is composed of framed steel panels. The required materials for fabrication and installation are as follows: galvanized sheets, frame, and panels. Four kinds of installation may be done: Installation A using a single layer reference specimen, Installation B using double layer reference specimen with a common plate, Installation C using double layer reference specimen with separate plates-empty cavity, and Installation D using double layer reference specimen with separate plates and added layer of sound-absorbing material in the cavity.
SCOPE
1.1 This specification describes the construction and installation of standard reference specimens for quality control of laboratory sound transmission loss measurements using Test Method E90.  
1.2 Laboratories may choose to construct and test all of the reference specimens described here or only a subset. Specific specimens may be required by a test method or an accrediting agency.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

4. Construction of Reference Specimen
4.1 General:
4.1.1 The reference specimen is composed of framed steel panels. The required materials for fabrication and installation are as
follows:
Galvanized steel sheets—width, 1220 mm (4 ft); nominal thickness, 0.63 mm
(24 gauge). The weight of the sheets shall be 5.1 ± 0.7 kg/m (1.05 ± 0.15 lb/
ft ).
Steel right angles with 25-mm (1-in.) flanges—metal thickness, 3.2 mm ( ⁄8 in.).
Blind rivets—diameter, 3.2 mm ( ⁄8 in. ).
Duct tape, 50 mm (2 in.) wide.
Drywall screws, Type W—length, 32 mm (1.25 in.).
Bolts #10–24 —25 mm (1 in.) long with appropriate nuts and washers.
Fasteners, to hold wood frame to the perimeter of the test opening.
Non-hardening, caulking,
Nominal 2 by 4 in. wood framing, approximately 40 by 90 mm.
NOTE 1—The quantity and length of each component needed depends
on the size of the laboratory test opening.
NOTE 1—To simplify cleaning, the wood framing used to support the
steel panels may be painted.
4.1.2 The weight of each component of the reference specimen and the assembled specimen shall be measured and kept on
record. In addition, the thickness of each of the steel panels shall be measured in six locations. (See Appendix X1.)
4.2 Assembly:
4.2.1 Galvanized Sheets—The length of each galvanized sheet shall be a few millimetres less than the height of the laboratory
test opening. The total width of all the sheets shall be a few millimetres less than the width of the laboratory test opening. This
may require that one or more sheets be cut lengthwise. The intent is that, when installed, the panels fill the test opening completely.

FIG. 1 Notching and Welding Corners of Steel Angles
4.2.2 Frame—Cut steel right angles to size to form a frame for each sheet; the frame shall have the same outside dimensions
as the sheets. Notch and weld the steel angles to form the four corners of the frame as shown in Fig. 1. Alternatively, miter the
angles and weld similarly. Smooth corners after welding.
4.2.3 Panels—Construct a panel by riveting steel sheets to the frames as follows:0
4.2.3.1 Drill holes at 100 mm (4 in.) on-center around the perimeter of the sheets for the installation of the blind rivets. To ensure
proper alignment of the sheets with the frame, it is recommended to drill a few holes and then install rivets to hold the sheet in
place. Once this is done, the remaining holes may be drilled and the rivets installed. Position these holes to avoid conflict with the
clearance holes described in 4.2.3.2.
4.2.3.2 Drill 4 mm ( ⁄32 inch) diameter holes through the horizontal members of the frame and sheet as shown in Fig. 2. These
are clearance holes for the drywall screws used to attach the panel to the wood plate (see 5.4). Drill similar holes through the
vertical members of the panels that will be used to attach the assembled specimen to the vertical wood plates. The spacing between
these holes is not important.
4.2.3.3 Drill 6.4 mm ( ⁄4 in.) diameter holes at 406 mm (16 in.) on-center through the vertical flanges of the steel frame. These
are clearance holes for the bolts used to connect the panels together (see 5.3 and Fig. 3). The holes in adjacent vertical members
should be carefully aligned with each other to ease installation of the panels.
5. Installation A: Single Layer Reference Specimen
5.1 Using approximately 40 mm by 90 mm wood studs (nominal 2 in. by 4 in.), install a wood frame around the perimeter of
the laboratory opening. Use a double bead of caulking between the wood frame and the surface of the laboratory opening. Use
suitable fasteners no more than 305 mm (12 in.) on-center.
5.2 Place the reference specimen against the wood frame with the flanges of the panel frames as shown in Fig. 4.
NOTE 1—The panels are positioned 75 mm from the mid-plane of the laboratory test opening to minimize changes when laboratories intend to test other
reference specimens described in this document that use separate plates.
NOTE 2—The direction of sound transmission for these reference specimens is not important. It can be left-to-right or right-to-left.
5.3 Insert 25-mm (1-in.) long No. 10-24 bolts or equivalent through the holes in adjacent vertical flanges drilled according to
4.2.3.3. Washers may be used if desired. Tighten nut snugly to close the gap between adjacent panels. (See Fig. 3).
5.4 Fasten the test panels to the vertical and horizontal sections of the wood frame with Type W drywall screws 32 mm (1.25
in.) long inserted through the holes drilled according to 4.2.3.2.
5.5 Seal the test panel joints on both sides with a single layer of 50-mm (2-in.) wide duct tape (centered on the joints).
5.6 Seal the perimeter joint on b
