More A Covered are the procedures for longitudinal Charpy V-notch testing, which contain two testing frequencies. The two frequencies for testing H and P , frequency H heat testing, and frequency P piece testing, are discussed and presented in details. This abstract is a brief summary of the referenced standard.

A number in parentheses indicates the year of last reapproval. This standard has been approved for use by agencies of the U. Department of Defense. The impact properties of steel can varywithin the same heat and piece, be it as rolled, control rolled,or heat treated. The purchaser should, therefore, be aware thattesting of one plate, bar, or shape does not provide assuranceall plates, bars, or shapes of the same heat as processed will beidentical in toughness with the product tested.
Normalizing orquenching and tempering the product will reduce the degree ofvariation. Within the text, the SI units areshown in brackets. The values stated in each system are notexact equivalents; therefore, each system must be used inde-pendently of the other.
Combining values from the two systemsmay result in nonconformance with this specification. Referenced Documents2. Ordering Information3.
Current edition approved March 1, Published April Originallyapproved in DOI: United States1Copyright by ASTM Int l all rights reserved ;product thickness, and the length of the notch shall beperpendicular to the rolled surface of the product. Frequency of Testing5. The impact test s shall betaken from different as-rolled or heat-treated pieces.
When material rolledover 2 in. If insufficient pieces of the thickest orthinnest material are produced to permit compliance with theabove, then testing may proceed to the next nearest thicknessavailable.
When plates are produced from coils, three impacttests shall be taken from each qualifying coil see 4. Onesuch coil shall be tested for each 50 tons [45 Mg] of the sameproduct produced on the same mill from the same heat of steel. When plates are produced from coils,three impact tests shall be taken from each coil. If the shapes are heat treated, one testshall be taken from each heat of each furnace lot. For shapesheat treated in a continuous furnace, a lot shall not exceed 15tons [15 Mg].
Formaterial heat treated in a noncontinuous furnace, one test shallbe taken from each heat of the same bar diameter or thicknessfor each furnace charge. Heat Treatment6. If the heat treatment tempera-tures are not indicated on the purchase order, the manufactureror processor shall heat treat the specimens under conditionsNOTE 1—The notch for any of the specimens can be on either side of the beam centerline.
The plate manufacturer or processorshall inform the purchaser of the procedure followed in treatingthe specimens. At the option of the manufacturer orprocessor retests may be made on the rejected material inwhich case each piece shall be accepted or rejected on the basisof the results of its own test. Test Reports8. However, for H frequency, only one testneed be reported when the amount of material from a shipmentis less than 50 tons [45 Mg] or two tests when the amount ofmaterial from a shipment is 50 tons [45 Mg] or more.
Tests from material thicknesses inaccordance with 5. These test thicknesses may or may not be withinpreviously tested and shipped thicknesses from the same heat. If only half or less ofa coil is utilized, then only one test from the outer lap and onefrom the innermost portion shipped need be reported.
However,the document shall clearly identify the organization submittingthe report. Notwithstanding the absence of a signature, theorganization submitting the report is responsible for the contentof the report. The survey dataconsists of test values obtained from six locations in addition tothe locations shown in Fig.
