Understanding corrosion, and corrosion rates, is necessary to ensure that the design of objects we interact with every day, from the bridges we drive over to the containers used to transport chemicals, from the pipes that carry our water to the utensils we cook with, are safe and perform to specifications.","The Corr-Data dataset was created by the staff of the NACE-NIST Corrosion Data Program. This program was established by a joint agreement between NACE (National Association of Corrosion Engineers) International and NIST (National Institute of Standards and Technology) in Dec. of 1982 and ran until 1997. At its founding, the objective of this program was to provide engineers with software for the then new personal computers that would help them solve corrosion problems. Over the 15 years this program ran, over 20 databases and expert advisory systems for alloys selection were produced and released. While software can go out of date, the data remains relevant. The data describe observations of various samples in potentially corrosive environments under particular conditions (concentrations and temperatures) to see if, how, and at what rate they corrode. The data include over 24,000 records which have been extracted from over 250 different source documents.","The data provided here is from published results, but it should only be considered indicative of how the specified material was observed to perform in the given environment one time. The user needs to keep in mind that corrosion is a highly stochastic process and that behavior can vary greatly with small variations in the environment or material. This data is provided to help users select materials for further evaluation and should not be considered, or construed, as advice on the usability of any material in any environment. Only thoroughly evaluated test results for the whole range of material, loading, and environmental conditions should be used for critical decision making."],"keyword":["corrosion","NACE"],"theme":["Materials:Materials

steel at elevated temperatures, especially under shear loading, is not well established in the literature. Set of data presents results from recently conducted tests on high-strength structural bolts subject to double shear loading at elevated temperatures. The parameters varied between tests included the bolt grade, bolt diameter, and temperature. Bolt grades A325 and A490 were tested. For each bolt grade, three different diameters were tested (19 mm (3/4 in), 22 mm (7/8 in), and 25.4 mm (1 in)) at five different temperatures (20 ºC, 200 ºC, 400 ºC, 500 ºC, and 600 ºC). At least three tests were conducted for each combination of parameters. The load versus displacement curves are presented herein. The results from these experiments fill a critical knowledge gap currently present in the literature regarding the behavior of high-strength structural bolts under shear loading at elevated temperatures. These data will ultimately provide a thorough understanding of the overall behavior of structural steel systems under realistic fire loading by clarifying the (i) shear behavior of high-strength structural steel bolts at elevated temperatures, and (ii) degradation in the mechanical and material properties of high-strength steel bolts with increasing temperatures. It is noted that additional details, experimental procedures, and uncertainty analysis for this experimental series are provided in in the publications listed below. Description: This data set is presented in six files. One file for each diameter size (19 mm (3/4 in), 22 mm (7/8 in) and 25.4 mm (1 in)) for both bolt types (A325 and A490). Within the files, there are separate tables representing the load-displacement curves for each test. Each test was assigned a unique name. The nomenclature includes the bolt diameter, type, test temperature, and specimen number. For example, test \"19A325T20-1\". The first two digits represent the bolt diameter (19 mm (3/4 in), 22 mm (7/8 in), or 25.4 mm (1 in)), the next four characters represent the bolt type (A325 or A490), followed by the letter T and the temperature at which that bolt was tested (T20= 20 ºC (Ambient Temperature); T200= 200 ºC; T400= 400 ºC; T500= 500 ºC; T600= 600 ºC), and lastly, the number of the specimen."],"bureauCode":["006:55"],"contactPoint":{"hasEmail":"mailto:mina.seif@nist.gov","fn":"Mina Seif"},"accessLevel":"public","@id":"ark:/88434/mds00bx4k3","publisher":{"@type":"org:Organization","name":"National Institute of Standards and Technology"},"doi":"doi:10.18434/mds2-1852","license":"https://www.nist.gov/open/license","language":["en"],"modified":"2016-08-15 00:00:00","ediid":"55CC9271C9B75BE9E0531A57068105501852","components":[{"accessURL":"https://doi.org/10.18434/M33T0T","@type":["nrdp:AccessPage","dcat:Distribution"],"@id":"#10.18434/M33T0T","_extensionSchemas":["https://data.nist.gov/od/dm/nerdm-schema/pub/v0.7#/definitions/AccessPage"]}],"status":"available","version":"1.0.1","releaseHistory":{"@id":"ark:/88434/mds00bx4k3.rel","@type":["nrdr:ReleaseHistory"],"hasRelease":[{"version":"1.0.0","issued":"2016-08-15","@id":"ark:/88434/mds00bx4k3/pdr:v/1.0.0","location":"https://data.nist.gov/od/id/ark:/88434/mds00bx4k3/pdr:v/1.0.0","description":"initial release"},{"version":"1.0.1","issued":"2016-08-15 00:00:00","@id":"ark:/88434/mds00bx4k3/pdr:v/1.0.1","location":"https://data.nist.gov/od/id/ark:/88434/mds00bx4k3/pdr:v/1.0.1","description":"metadata update"}]},"annotated":"2021-11-08T21:26:52.688237","revised":"2021-11-08T21:26:00.723423","issued":null,"firstIssued":"2021-11-08T21:26:00.723423"},{"landingPage":null,"bureauCode":["006:55"],"contactPoint":{"fn":"Lee Yu","hasEmail":"mailto:lee.yu@nist.gov"},"@id":"ark:/88434/mds00d1jmk","keyword":["food","nutrition","dietary supplements","standard reference materials","reference materials","SRM","RM","Food and Nutrition"],"inventory":[{"childCount":2,"byType":[{"forType":"dcat:Distribution","childCount":1,"descCount":3},{"forType":"nrd:Hidden","childCount":1,"descCount":1},{"forType":"nrdp:DataFile","childCount":0,"descCount":2},{"forType":"nrdp:Subcollection","childCount":1,"descCount":1}],"descCount":4,"childCollections":["1855"],"forCollection":""},{"childCount":2,"byType":[{"forType":"dcat:Distribution","childCount":2,"descCount":2},{"forType":"nrdp:DataFile","childCount":2,"descCount":2}],"descCount":2,"childCollections":[],"forCollection":"1855"}],"doi":"doi:10.18434/M3PM35","modified":"2017-08-18","@context":["https://data.nist.gov/od/dm/nerdm-pub-context.jsonld",{"@base":"ark:/88434/mds00d1jmk"}],"@type":["nrdp:PublicDataResource"],"description":["A comparison of the expanded uncertainty for certified values of iodine in food matrix CRMs. The CRMS were found by searching The European Virtual Institute for Speciation Analysis (EVISA) database using the terms \"Iodine\" and \"Certified\" in the Material category.
