The rebar's which have been delivered to the site will be released for fabrication only after it is confirmed that the relevant independent tests show successful results. 3. Mill certificates from the manufacturer, which include tensile and bend test results, will be submitted to the Engineer with every delivery of rebars to the stockyard. 4.
Wednesday, 03 May 2017. The new Qatar Steel-backed steelworks in Bellara, Jijel province, 300 km east of Algiers, has started rebar production tests, sources close to the mill told Platts. The test is being conducted by engineering company Danieli, which designed and delivered the first rolling mill to the site in April.
The mill test report for steel bars shall also show the results of complete chemical tests. The mill test report shall be compared against the requirements of the proper AASHTO Specification to ensure contract compliance. 1036.2.1 Reinforcing Steel, Dowel Bars, Mechanical Bar Splices and Cold Drawn Wire and Welded Wire Fabric
In-place inspection of rebar starts with the mill test report and may be supplemented by a report from an independent testing laboratory. Re-ports should state grade of steel, ten-sile properties, chemical composition (and carbon equivalent if rebar is to be welded), and spacing and height of deformations. Compare these val-ues with those in ...
A Rebar Mill with an annual production capacity of 0.8 million tons was added. A combined rebar and wire-rod mill with an annual production capacity of 0.5 million tons was added. The capacity has been increased over the years to the present 0.7 million tons. Another Wire-Rod Mill with an annual production capacity of 0.5 million tons was added.
The report described a series of bending and straightening tests on Grade 60 reinforcing bars performed by Wiss, Janney, Elstner & Associates, Inc. (WJE No. 78282, April 6, 1982). Among the test variables were mill sources (3), bar sizes (#5, #8 and #11), bend diameters (ACI 318 and half ACI 318), orientation of bending axis (weak and strong ...
A range of individual markings reveal the identification of each individual rebar: The first letter or symbol means producing mill and deformation pattern.. The second marking means the bar size, in this picture, " 11 " means the diameter of this rebar is #3.; The third letter represents the type of steel as follow: . S: Carbon-steel (A615).
How to Test Tensile Strenght of Rebar. Firstly, it is required to select the samples for testing. Sampling is done as per the relevant code of practices or project specifications. According to BS 4449:2005, three test pieces for each nominal diameter for every 30 tons shall be tested.
The mill reports certify that the reinforcing bar conforms to the project specifications and reveals the chemical composition of the reinforcing bar and mechanical properties. Reinforcing bars typically come in two primary grades: Grade 60, which has a minimum yield strength of 60,000 psi, and Grade 75, which has a yield strength of 75,000 psi.
Mill Test Certificate(MTC),or Mill Test Report (MTR),is issued by a manufacturer to certify the chemical and mechanical features of a product and its compliance to the applicable norms and technical specifications.Typically,mill test certificates conform to the EN 10204 standard and are related to steel products.Certification of steel plates rolled in Europe is generally to EN …
Every supply of CSN50 Rebar comes with a mill test certificate, where the traceability of the material is ensured individually for each bundle or roll, containing the results obtained in mechanical tests for release. Identification Label.

Inspector signs on certified mill test . A Certificate of Compliance that epoxy coating and coating process conform to specs.
The most common extensometers used in rebar testing are manual clip-on style instruments that are attached directly to the rebar by the operator prior to running the test. If the instrument is not designed to remain on through failure, it must be manually removed by the operator after yielding occurs, but before the specimen fails.
mill test report for each heat included in the delivery. The mill test report must include the following: a. Producer information b. Heat number and size of rebar represented by the report c. The grade for which the steel qualifies d. Tensile test results including yield strength, tensile strength and elongation e.
Material test report or Mill test report certifies that the chemical analysis and mechanical properties are in conformance with the specified specification. An MTR certifies a material's compliance with the standard specification such as ASME Section II Part A and B or ASTM. The MTR is supplied from the material manufacturer such as plate ...
