E691 practice for conducting an interlaboratory study to determine the precision of a test method.

Sheet type metallic specimen.

Type specimen sheet brief to produce an a2 specimen sheet of chosen typeface purpose is to explain and promote typefaces to designers who may want to use buy it. E1012 practice for verification of testing frame and specimen alignment under tensile and compressive axial force application. According to e 21 specimens should be round whenever the material dimensions allow for this geometry exceptions are for sheet or strip type materials. Numerous structural examinations of steel sheet have shown that the work hardened zone along the cutting line is generally a maximum of 10 of specimen thickness.

Nowadays test pieces from steel sheet and metal foils are produced economically and accurately using specimen blanking machines. As result of the improvement of sheet metal grades the tensile strength of the sheet metal plates increases more and more. Good testing starts with a good specimen.

Cutting force p in kn. The slight punch oversize and thus the work hardening is removed with the specimen grinder. Today the typical press for sheet metal testing industry is a punch with 1000 or 1200 kn 100 to 120 tons. Bars tubes sheets pin loaded specimens round specimens and powdered metallurgy products are some of the many options for testing to this standard.

Due to the low cutting speed and the shape of the blanking tool the work hardening of the cut edge amounts to max.

Poster is limited to black white and tones of grey poster must include. 10 of the specimen thickness. For the economical manufacture of tensile specimens from sheet steel. However the most common specimen is a dogbone shaped rectangle with a width of 12 5 mm 0 5 in and gauge length of 50 mm 2 in.

Mm 0 500 to 0 750 in use either the sheet type specimen of 6 3 the plate type specimen of 6 2 or the largest practical size of round specimen described in 6 4. Even in the range of hot deforming. Standards stipulate that test results must not be influenced by any material change caused by work hardening in the specimen edge zone. E345 test methods of tension testing of metallic foil.
