A mill test report (MTR) and often also called a certified mill test report, certified material test report, mill test certificate (MTC), inspection certificate, certificate of test, or a host of other names, is a quality assurance document used in the metals industry that certifies a material's chemical and physical properties and states a product made of metal (steel, aluminum, brass or ...
Typically, a supplier performs the FAI and the purchaser reviews the report. The FAI process usually consists of fully testing and inspecting either the first part produced by the new process or a sample from the first batch of parts. First article inspection is typically a purchase order requirement of the purchaser for the supplier to complete.
USP grade meets the purity levels set by the United States Pharmacopeia (USP). USP grade is equivalent to the ACS grade for many drugs. NF grade is a purity grade set by the National Formulary (NF). NF grade is equivalent to the ACS grade for many drugs. British Pharmacopoeia: Meets or exceeds requirements set by the British Pharmacopoeia (BP ...
Monographs may also detail USP Reference Standards and/or other materials needed for test performance. The FCC's appendices contain step-by-step guidance for general physical and chemical tests, and apparatus use, as well as generally useful information, such as food ingredient good manufacturing practices .
One process for X-ray fluorescence assay involves melting the material in a furnace and stirring to make a homogeneous mix. Following this, a sample is taken from the centre of the molten sample. Samples are typically taken using a vacuum pin tube. [4] The sample is then tested by X-ray fluorescence spectroscopy. Metallurgical assay is ...
The United States Pharmacopeia (USP) outlines several tests that can be done to quantitatively determine the bioburden of non-sterile drug products. [ 4 ] It is important when conducting these tests to ensure that the testing method does not either introduce bacteria into the test sample or kill bacteria in the test sample. [ 4 ]
It is common for engineering drawings to specify one form over the other. Bar stock is generally close to 1/2 of the cost of plate on a per pound basis. So although the material form isn't directly related to the geometry of the component, cost can be removed at the design stage by specifying the least expensive form of the material.
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. [1] A specification is often a type of technical standard . There are different types of technical or engineering specifications (specs), and the term is used differently in different technical contexts.
