Trace element analysis of metals and alloys
| Description: | Determination of trace elements in metals and alloys. Metal and alloy samples are digested in strong acid and required trace elements quantified by ICP-MS down to the ng/g range (DL are element-dependent). Alternatively, larger samples can be analyzed directly by spark-OES without digestion. |

Detection of free iron on stainless steels (Practice F: For ferritic and martensitic steels of the 400 series)
| Description: | The samples are tightly wrapped in paper towels. Prior to wrapping the paper towels are soaked in distilled water. The wrapped samples are then put in a glass dish with a lid on top to prevent evaporation. After 60 minutes, the samples are dried in a dry box. The test is positive if rust is detected visually or under the light-optical microscope at a 20x magnification. The term free iron means iron present on the surface of parts, including but not limited to iron contaminations, iron-tool marks, residual iron. salts from pickling solutions, iron dust, atmospheric exposure, iron deposits in welds, embedded iron and iron oxide.

Detection of free iron on stainless steels (Practice E: For austenitic steels of the 200 and 300 series)
| Description: | The samples are placed in a glass vessel filled with test solution. After 30 seconds, the samples are placed in a beaker containing distilled water and then dried in a drybox. The test is positive when a dark blue discoloration (Turnbulls blue) is visible 30 s later by eye or under the light-optical microscope (20x magnification). The term free iron means iron present on the surface of parts, including but not limited to iron contaminations, iron-tool marks, residual iron. salts from pickling solutions, iron dust, atmospheric exposure, iron deposits in welds, embedded iron and iron oxide.
