There is a 10 parts per million (ppm) limit for lubricant base oils (e.g., mineral oil) that can be present in food if incidental contact occurs. To get new food contact substances (FCSs) approved by the FDA, manufacturers must either submit a Food Contact Notification (FCN) filing or apply for a Threshold of Regulation (TOR) exemption.

Food industry equipment should be constructed of sanitary design; however, some automated processing equipment by necessity is difficult to clean. An individual SSOP should include: [citation needed] The equipment or affected area to be cleaned, identified by common name; The tools necessary to prepare the equipment or area to be cleaned
The RCA clean is a standard set of wafer cleaning steps which need to be performed before high-temperature processing steps (oxidation, diffusion, CVD) of silicon wafers in semiconductor manufacturing. Werner Kern developed the basic procedure in 1965 while working for RCA, the Radio Corporation of America.

An automated tank cleaning machine is a machine used to clean cargo, process, underground storage tanks and similar equipment such as those found in tank trucks, railroad cars, barges, oil tankers, food and beverage manufacturing facilities, chemical processing plants, ethanol ...
Equipment used in aseptic processing of food and beverages must be sterilized before processing and remain sterile during processing. [1] When designing aseptic processing equipment there are six basic requirements to consider: the equipment must have the capability of being cleaned thoroughly, it must be able to be sterilized with steam, chemicals, or high-temperature water, sterilization ...
Aqueous parts cleaning industrial washer. Parts cleaning is a step in various industrial processes, either as preparation for surface finishing or to safeguard delicate components. One such process, electroplating, is particularly sensitive to part cleanliness, as even thin layers of oil can hinder coating adhesion.
With one unpaired electron μ eff values range from 1.8 to 2.5 μ B and with two unpaired electrons the range is 3.18 to 3.3 μ B. Note that low-spin complexes of Fe 2+ and Co 3+ are diamagnetic. Another group of complexes that are diamagnetic are square-planar complexes of d 8 ions such as Ni 2+ and Rh + and Au 3+.
