This is called a limited calibration. But if the final measurement requires 10% accuracy, then the 3% gauge never can be better than 3.3:1. Then perhaps adjusting the calibration tolerance for the gauge would be a better solution. If the calibration is performed at 100 units, the 1% standard would actually be anywhere between 99 and 101 units.
The preparation of certified reference materials is described in general in ISO Guide 17034 [16] and in more detail in ISO Guide 35. [17] Preparation of biological reference standards is described in WHO Guidance. [9] General steps required in production of a certified reference material typically include: [17] Collection or synthesis of material
Eating your own dog food or "dogfooding" is the practice of using one's own products or services. [1] This can be a way for an organization to test its products in real-world usage using product management techniques. Hence dogfooding can act as quality control, and eventually a kind of testimonial advertising. Once in the market, dogfooding ...
The Hounsfield unit (HU) scale is a linear transformation of the original linear attenuation coefficient measurement into one in which the radiodensity of distilled water at standard pressure and temperature is defined as 0 Hounsfield units (HU), while the radiodensity of air at STP is defined as −1000 HU.

A 2005 consumer alert was released for contaminated Diamond Pet Foods for dogs and cats. Over 100 canine deaths and at least one feline fatality have been linked to Diamond Pet Foods contaminated by potentially deadly aflatoxin, according to Cornell University veterinarians. [129]
Evaluators sometimes combine elements during the actual test. If a dog fails the test initially, owners can continue training with their dog and retake for the test in the future. If all ten objectives are met, the handler can apply for a certificate and special dog pet tag from the AKC stating that the dog has earned the CGC. [7]
A monitor unit (MU) is a measure of machine output from a clinical accelerator for radiation therapy such as a linear accelerator or an orthovoltage unit. Monitor units are measured by monitor chambers, which are ionization chambers that measure the dose delivered by a beam and are built into the treatment head of radiotherapy linear accelerators.
