Adhesive Shear Strength of Resilient Flooring and Carpet Adhesives ASTM D6004
ASTM D6004 covers shear strength testing of adhesives used to bond resilient flooring and carpets to specific substrates. Lap-jointed specimens made from adhesively bonded wood and Duck cloth are subjected to shear testing.The ASTM D6004 adhesive shear strength is expressed in pounds per square inch (psi).
Standard method ASTM D6004 describes the test for shear strength of adhesives used to bond resilient flooring and carpets to specific substrates (e.g carpet underlayments). It provides a quantitative basis for measuring and recording shear strength of various adhesive and underlayment combinations. Shear loading is the most common cause for failure of such joints, hence the importance of measuring shear strength. In flooring applications, the applied load will vary depending on the traffic. Heavy traffic areas (such as in airports) will impose maximum flooring loads, while moderate traffic and loads may exist in office areas. Residential or hotel rooms are typical light traffic areas.
Three wooden underlayment pieces are prepared as specified and adhesive applied by trowel as per manufacturer’s instructions. A section of each piece is kept free, as it needs to be gripped in the shearing fixture. Duck cloth (natural, untreated, #10, 14.73 oz.) representing the carpet material stuck over the area of adhesive application on each wooden piece such that a small portion of cloth juts-out, to enable gripping by the shearing fixture. A 10 lb deadweight is placed on each specimen to ensure that bonds will form. The three adhesively bonded lap shear specimens, are then kept in a convection oven for the specified duration (upto two weeks) at 122 °F ± 2°F. The samples are then subjected to 180° shear testing, which involves shearing the joint by pulling the underlayment and the Duck cloth in opposite directions. The testing can be done on any universal testing machine, but a special shear fixture is needed for ASTM D6004, since the shear must be uniformly applied across the area of contact. The applied force should be ≥30 psi for specimens meant for heavy traffic, ≥ 20 psi for moderate traffic and ≥ 12 psi for light traffic. The stress value at joint failure is recorded.
Each underlayment sample will be 2 inch × 3 inch. The Duck cloth can be of the same size, but with a portion jutting-out for gripping and pulling.
The ASTM D6004 adhesive shear strength is reported in pounds per square inch (psi).
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 is a standard test method for the analysis of sulfochromate etches solution used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
