A quality control system (QCS) refers to a system used to measure and control the quality of moving sheet processes on-line as in the paper produced by a paper machine. . Generally, a control system is concerned with measurement and control of one or multiple properties in time in a single dimen
Quality control (QC) is a process by which entities review the quality of all factors involved in production. ISO 9000 defines quality control as "a part of quality management focused on fulfilling quality requirements". [1] This approach places emphasis on three aspects (enshrined in standards such as ISO 9001): [2] [3]
The Cooper-Harper Handling Qualities Rating Scale [1] (HQRS), sometimes Cooper-Harper Rating Scale (CHRS), is a pilot rating scale, a set of criteria used by test pilots and flight test engineers to evaluate the handling qualities of aircraft while performing a task during a flight test. The scale ranges from 1 to 10, with 1 indicating the best ...
3: Weather-resistant. Protects against falling dirt and windblown dust, against weather hazards such as rain, sleet and snow, and is undamaged by the formation of ice. Used outdoors on ship docks, in construction work, and in tunnels and subways. 3R: As 3, but omits protection against windblown dust. 3S: As 3, but also operable when laden with ice.
A rating scale is a set of categories designed to obtain information about a quantitative or a qualitative attribute. In the social sciences , particularly psychology , common examples are the Likert response scale and 0-10 rating scales, where a person selects the number that reflecting the perceived quality of a product .
Moisture sensitivity level (MSL) is a rating that shows a device's susceptibility to damage due to absorbed moisture when subjected to reflow soldering as defined in J-STD-020. It relates to the packaging and handling precautions for some semiconductors.
Aircraft were originally divided into six QC bands from 0.5 to 16, but following a review by the Department for Transport [1] a seventh category – Quota Count 0.25 – was added in March 2007 [2] and an eighth category – Quota Count 0.125 – in September 2018. [3]
The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.
