CCSi features this high quality Williams' Parallel Plate Plastometer for the evaluation of the plasticity and recovery of unvulcanized, uncompounded, compounded and reclaim rubber as described in ASTM D926 "Standard Test Method for Rubber Property — Plasticity and Recovery (Parallel Plate Method).". The Williams' Plastometer features construction of high carbon content steel, which ...

Standards in Fireproofing

test probes include the make and model of the gear motor, probe shaft geometry, probe plate configuration and torque monitoring calibration information. The helical test probe can be used to determine an "effective cohesion" profile with depth based on the helical plate area (Ah), an assumed torque correlation coeffi-

Cohesion Testing System – Chemgrout

The tensile pull-off method for adhesion testing, as outlined in ASTM D 4541 and similarly in BS EN ISO 4624, involves gluing a test dolly to the coated surface and then pulling the dolly by exerting a force perpendicular to the surface in an effort to remove the dolly with the coating from the substrate.

Lombardi SA

The cohesion of grout was determined at 30 ± 1 min with a Lombardi plate cohesion meter. A thin galvanized steel plate (100×100×1 mm) with known weight was immersed in the grout and hung on a stand placed on an electronic balance. The difference in weight values before and after immersion into the grout (dW) is determined.

ASTM C1585

File Test: Begin by sawing off a portion of the plated part and look for signs of detachment at the deposit or substrate interface. Then raise the sawed edge with a coarse mill file. Evidence of lifting or peeling is an indication of poor adhesion. Impact Test: Use hammer or other blunt object to pound the coated part. Signs of exfoliation or ...

You can use any of these methods to test plastic welds made by commercially available welding equipment (injection, hot air/hot gas, extrusion, ultrasonic, hot plate, etc.). This is intended to be a quick overview of the testing and inspection methods for welded plastic parts.

Relationship between soil cohesion and shear strength

4.4 This test method differs from Test Method C642 in which the specimens are oven dried, immersed completely in water at 21°C, and then boiled under water for 5 h. In this test method, only one surface is exposed to water at room temperature while the other surfaces are sealed simulating water absorption in a member that is in contact with water on one side only.

measurement of cohesion becomes more important. An instrument such as a shear vane, a penetrometer, a Lombardi plate or a Baroid rheometer can be used. 2.2 Resistance to Pressure Filtration Injecting grouts into small apertures is similar to pressing the grout against a filter material.

Regarding Adhesion Test; the Way I see it, if Para. 3.4.2 of AMS2460 [affil. link to spec at Techstreet] - Chrome Plating prohibits the use of mandrel ("no mandrel") the proper test would then be para. 3.2 of ASTM B571 [affil. link to spec at Techstreet] - bend to failure/rupture. Para 3.1 requires a mandrel and therefore can't be used. Nadcap ...

Such responses of fluidity included mini-slump, flow time using Marsh cone and cohesion measured by Lombardi plate meter and unit weight, and compressive strength at 3 d, 7 d and 28 d. The models are valid for mixes with 0.35 to 0.42 water-to-binder ratio (W/B), 10 % to 40 % of pulverised fuel ash (PFA) as replacement of cement by mass, 0.02 to ...

Chrome plating adhesion standards and tests

In such circumstances, travel can be limited through the increase in cohesion. For the measurement of this grout cohesion, Lombardi developed a plate cohesiometer, also referred to as P.C.M. It involves a thin plate of 100 x 100 x 1 mm with rough surfaces on which the grout – provided that it has some cohesion - can stick.
