Taber Specimen Mounting

Art. No.: 14688

Taber SH-75 Rimmed Specimen Holder

This holder is used for wet testing materials to determine the effect of absorbed and / or surface moisture on abrasion resistance.
Includes a 7.5 mm raised rim for retaining liquids during a test
A rubber pad is adhered to the table to prevent specimens from slipping during the test
To prevent splash over on the instrument, use only a sufficient amount of liquid to cover the specimen.
Specimens may be up to 140 mm diameter.

All Taber Abraser specimen holders are engineered with an innovative design that allows quick mounting and removal from the motor shaft. This enables the holder to be removed from the instrument so specimens can be inspected more closely.
To expand the versatility of the Taber® Rotary Abraser (Abrader), mounting options and interchangeable specimen tables are available to evaluate materials not easily tested with the standard configuration.
If a mounting card is used, the specimen should be approximately 108 mm in diameter. If no mounting card is used, a 135 mm specimen is required such that the clamp ring will grip the overlapped material.
Standard material thickness that can be evaluated with the Taber Rotary Platform Abraser is 6.5 mm
- The S-21 nut (10121) is used for materials greater than 6.5 mm but less than 12.5 mm
- Specimens with a thickness greater than 12.5 mm can be tested using the arm height extension kit (14691)
The width of the "Taber Test" wear path is 12.7 mm, and located 31.75 mm from the center of the specimen. For most rigid materials, a sample approximately 100 mm square is recommended.
- If the specimen is less than the suggested size, it is possible to position two or more specimens on a mounting card (10124, 10125) to meet the size requirement, or use the Sliding Mount Specimen Holder (14687). If the edges are not flush together or if the samples are of different thickness, the edges may wear at a different rate than the rest of the specimen.
- Flexible specimens are typically circular and require the use of the clamp ring.

Technical Data Chart

Data

14684*	Standard - test most rigid or flexible specimens; includes a threaded center post with a clamp plate and nut to secure rigid materials, rubber pad (S-19) for a non-slip surface. Specimen hold-down ring (14689 or 14690) recommended for testing flexible materials. For rigid specimens - 100 mm (square or round) with 6.5mm center hole / Flexible specimens - 125 mm with 6.5 mm center hole
14685*	Textile, Tensioning Type - similar to 14684, but includes a raised wear track to provide extra tensioning to the material when the clamp plate is tightened in the center recess and hold down ring is drawn down over the edge of the holder. Includes 14689 hold-down ring. For flexible specimens - 135 mm diameter with 6.5 mm center hole
14686*	Drive-Pin Type - use for rigid, square specimens that do not have a center-mounting hole. One corner of the specimen is positioned between two pins while two adjustable clamps are used to secure the specimen in place. For rigid specimens - 100 mm square
14687*	Sliding Mount - includes four adjustable mounts for testing four 50 mm square, rigid specimens. For rigid specimens - 50 mm square with one corner trimmed
14688*	Rimmed - includes a 7.5 mm raised rim to retain liquids, allowing you to determine the effect of absorbed or surface moisture on a material's resistance to abrasion. A rubber pad (S-19) prevents specimens from slipping during the test. For rigid specimens - 100 mm (square) or 140 mm (round) with 6.5 mm center hole
14689	Specimen Hold Down Ring "A" (108 mm ID) - for flexible materials. Use with 14684 or SH-12 specimen holder. For flexible specimens - up to 0.8 mm thick
14690	Specimen Hold Down Ring "B" (110 mm ID) - for flexible materials. Use with 14684 specimen holder. For flexible specimens - up to 1.5 mm thick
10121	Extension Nut - use with 14684 or when sample thickness is 6.5 mm to 12.5 mm. For rigid specimens - 100 mm (square or round) with 9.5 mm center hole
14691*	Arm Height Extension Kit - accommodates specimen thickness up to 40 mm by raising the position of the abraser arms. A set of 6 shims is included to ensure the correct abraser arm alignment, and positioning of the abrasive wheels. For a rigid specimens - 100 mm (square or round) with 13 mm center hole
*Intended for use with Taber Rotary Platform Abraser Models 1700 or 1750. Specimen holders are available for older style Taber Abrasers. Contact Taber Industries for additional information
10124	Mounting Card (108 mm square) - made from rigid card stock, coated on one side with pressure sensitive adhesive to affix to the specimen; a test record form is printed on the backside for permanent record of the test. Useful for testing flexible specimens that may wrinkle, stretch or bunch.
10125	Mounting Card (108 mm round) - similar to 10124, but round.
10126	Mounting Sheet (108 mm square) - coated on both sides with pressure sensitive adhesive. One side can be used to affix to the specimen and the other to provide a non-slip attachment of the specimen to the specimen holder; a test record printed on both sides enabling them to be used as a mounting card. Useful for testing materials difficult to drill a center hole (such as glass or ceramics).
