What is QC testing stand for?
Quality control (QC) is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. QC is similar to, but not identical with, quality assurance (QA).
What is QC QA and QI?
Quality Assurance (QA) is about fixing bugs in the product. Quality Control (QC) is about following processes to prevent bugs. Quality Improvement (QI) is about building and executing a quality program.
What is difference between QA & QC?
QA primarily focuses on the processes and procedures that improve quality, including training, documentation, monitoring and audits. QC focuses on the product to find defects that remain after development. QC professionals find these issues in a variety of ways, including software testing and beta or canary testing.
What is QC function?
The main function of quality control is to test and verify the product quality against the predefined standards. Therefore, quality control is the most important part of the pharmaceutical industry.
What are 4 types of quality control?
What Are the 4 Types of Quality Control? There are several methods of quality control. These include an x-bar chart, Six Sigma, 100% inspection mode, and the Taguchi Method.
What are the 4 types of quality assurance?
What are the 4 types of quality inspection?Pre-Production Inspection (PPI) ... During Production Inspection (DPI) ... Pre-shipment inspection (PSI) ... Container loading/loading supervision (LS) ... Piece-by-piece Inspections.
What is SOP quality?
SOPs are Level 2 quality documents and, along with other relevant quality documents, ensure the effectiveness and efficiency of quality systems. The ICH GCP guideline defines SOPs as “detailed, written instructions to achieve uniformity of the performance of a specific function”.
What are examples of quality control?
QC process assures that that the product being developed is of the required quality. Examples of quality control activities include inspection, deliverable peer reviews and the software testing process.
What does QC stand for?
quality controlQuality assurance (QA) and quality control (QC) are two terms that are often used interchangeably.
What is QC technician?
Quality control technicians are responsible for checking that products and services meet required quality and safety standards such as ISO 9001:2015, the matrix Standard and Investors in People. They work in a wide range of industries including food and drink, electronics and pharmaceuticals.
What is QC report?
You can view a Quality Control (QC) report for a completed analysis in Ion Reporter™ Software. The QC report provides a high-level summary of key metrics that you can use to evaluate the quality of the data. You can also download a PDF version of the QC report. In the Analysis tab, click Overview.

- Backflow
1. Flow of water in a pipe or line in a direction opposite to the normal flow; often associated with back siphonage or the flow of possibly contaminated water into a potable water system. - Backflow Preventor
1. A device or system installed in a water line to stop backflow from a non-potable source.
C -
- Calcite
1. Calcium carbonate (CaCO3). A trade name for finely ground limestone, very high in calcium carbonate, which is used to raise the pH of acidic water. - Calcium ( Ca )
1. One of the primary elements of the earth's crust commonly found in water as a dissolved solid. The presence of calcium in water is a factor contributing to the formation of scale and insoluble soap curds which are means of clearly identifying hard water. It is sometimes referred to as lime.

- Dealkalization
1. A process for the reduction of alkalinity in a water supply. It is generally accomplished by a chemical feed processor combined cation and anion exchange systems. - Deashing
1. The removal from solution of inorganic salts by means of adsorption by ion exchange resins of both the cations and the anions that comprise the salts.
E -
- Eductor
1. A venturiwith an opening at the throat used to educt (suck in) air or liquid. The common method of introducing brine into a water softener. - Efficiency
1. The effectiveness of the operational performance of an ion exchanger. Efficiency in the adsorption of ions is expressed as the quantity of regenerant required to effect the removal of a specified unit weight of adsorbed material, e.g., pounds of acid per kilogram of salt removed.

- Ferric Iron
1. Small solid iron particles containing trivalent iron, usually as gelatinous ferric hydroxide or ferric oxide (Fe2O3), which are suspended in water and visible as "rusty" water. Ferrous (iron in solution) is readily converted to ferric iron by exposure to oxygen found both in water and air. Ferric iron c… - Ferrous Iron
1. Usually ferrous hydroxide which when dissolved in water produces a clear solution. Often called clear water iron, it can be removed by ion-exchange.

- Gallon
1. A common unit of liquid volume; the US gallon has a volume of 231 cubic inches or 3.78533 liters; the British (Imperial) gallon has a volume of 277.418 cubic inches or 4.54596 liters. - GAC
1. Granular Activated carbon.
H -
- Halite
1. A geological term for rock salt, a mineral which is more than 95 percent sodium chloride. Also known as native or fossil salt. - Halogens
1. A family of elements that includes bromine, chlorine, fluorine, astatine, and iodine. They are very active chemically. They are commonly found as the ionic component in compounds with various other elements.

- Influent
1. The water entering a water treatment devise. - Inorganic Matter
1. Matter which is not derived from living organisms and contains no organically produced carbon; includes rocks, minerals and metals.
J -
- Jackson Turbidity Unit ( JTU )
1. An arbitrary unit of turbidity originally based on a suspension of specific type of silica with the turbidity measured in a Jackson Candle Turbidimeter. This has been replaced by the nephelometric turbidity unit (NTU).
