Proofing (armour)
The proofing of armour is testing armour for its defensive ability, most commonly the historical testing of plate armour and mail (armour). In the early Middle Ages, armour would be classified by the blows it could withstand, being certified as proof against swords, axes, and arrows. As firearms emerged as battlefield weapons, armour would be tested against them, as well, from which came the modern term "bulletproof". In Japan the testing of armor by arrow or a musket ball is called ''tameshi'' with the tested armor being called ''tameshi gusoku''. Helmet and chest armors were tested and many examples of these armors showing the bullet test marks still exist. In the 14th century, Japanese individual scale armor pieces were said to have been tested by arrows before being assembled into an armor.

Proofing (baking Technique)
In cooking, proofing (also called proving) is a step in the preparation of yeast bread and other baked goods in which the dough is allowed to rest and rise a final time before baking. During this rest period, yeast Fermentation in food processing, ferments the dough and produces gases, thereby Leavening agent, leavening the dough. In contrast, proofing or blooming ''yeast'' (as opposed to proofing the dough) may refer to the process of first suspending yeast in warm water, a necessary hydration step when baking with baker's yeast#Types of baker's yeast, active dry yeast.Instant dry yeast may be placed directly into flour without hydrating first. Proofing can also refer to the process of testing the viability of dry yeast by suspending it in warm water with carbohydrates (sugars). If the yeast is still alive, it will feed on the sugar and produce a visible layer of foam on the surface of the water mixture. Fermentation rest periods are not always explicitly named, and can appear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prepress Proofing
A contract proof usually serves as an agreement between customer and printer and as a color reference guide for adjusting the press before the final press run. Most contract proofs are a prepress proof. The primary goal of proofing is to serve as a tool for customer verification that the entire job is accurate. Prepress proofing (also known as off-press proofing) is a cost-effective way of providing a visual copy without the expense of creating a press proof. If errors are found during the printing process on press, correcting them can prove very costly to one or both parties involved. Press time is the most expensive part of print media. The main objective of proofing is to produce either a soft or hard copy of what the final product will look like on press. Hard-copy proofing usually involves ink-jet printing or other technologies (i.e. Laminate Proof) to produce high-quality one-off copies of the production artwork. Soft proofing usually involves highly color accurate wide-gam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proof Test
A proof test is a form of stress test to demonstrate the fitness of a load-bearing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items. Such a structure is often subjected to loads above that expected in actual use, demonstrating safety and design margin. Proof testing is nominally a nondestructive test, particularly if both design margins and test levels are well-chosen. However, unit failures are by definition considered to have been destroyed for their originally-intended use and load levels. Proof tests may be performed before a new design or unit is allowed to enter service, or perform additional uses, or to verify that an existing unit is still functional as intended.Test intervals for in-service ...

Proof (other)
Proof most often refers to: * Proof (truth), argument or sufficient evidence for the truth of a proposition * Alcohol proof, a measure of an alcoholic drink's strength Proof may also refer to: Mathematics and formal logic * Formal proof, a construct in proof theory * Mathematical proof, a convincing demonstration that some mathematical statement is necessarily true * Proof complexity, computational resources required to prove statements * Proof procedure, method for producing proofs in proof theory * Proof theory, a branch of mathematical logic that represents proofs as formal mathematical objects * Statistical proof, demonstration of degree of certainty for a hypothesis Law and philosophy * Evidence, information which tends to determine or demonstrate the truth of a proposition * Evidence (law), tested evidence or a legal proof * Legal burden of proof, duty to establish the truth of facts in a trial * Philosophic burden of proof, obligation on a party in a dispute to pro ...

Bulletproofing
Bulletproofing is the process of making an object capable of stopping a bullet or similar high velocity projectiles (e.g. shrapnel). The term bullet resistance is often preferred because few, if any, practical materials provide complete protection against all types of bullets, or multiple hits in the same location, or simply sufficient kinetic (movement) energy to overcome it. Origins In 1887, George E. Goodfellow, of Tombstone, Arizona, documented three cases where bullets had failed to penetrate silk articles of clothing. He described the shooting death of Charlie Storms by gambler Luke Short. Although Storms was shot in the heart, "not a drop of blood" exited the wound. Goodfellow found that, though the bullet did indeed kill Storms, it failed to pass through a silk handkerchief. The handkerchief essentially caught the bullet, but not sufficiently to stop the bullet penetrating Storms. Another example was the killing of Billy Grounds by Assistant City Marshal Billy Breakenr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fireproofing
Fireproofing is rendering something (structures, materials, etc.) resistant to fire, or incombustible; or material for use in making anything fire-proof. It is a passive fire protection measure. "Fireproof" or "fireproofing" can be used as a noun, verb or adjective; it may be hyphenated ("fire-proof"). Applying a certification listed fireproofing system to certain structures allows them to have a fire-resistance rating. The term "fireproofing" may be used in conjunction with standards, as reflected in common North American construction specifications. An item classed as fireproof is resistant in specified circumstances, and may burn or be rendered inoperable by fire exceeding the intensity or duration that it is designed to withstand.
