GRAMS METHOD [12 fiches]

Fiche 1 2012-10-04

Anglais

Subject field(s)
  • Steelmaking
DEF

cokes: The standard grades of hot-dipped tinplates, that carry about 0.56 kg of tin per basis box (i.e. lighter coating than the charcoal grades), that consist of mild-steel coated with tin, and that are used for packaging, canning and general purposes.

CONT

Various grades of hot-dipped tin plate were produced, the terminology indicating in a general way the weight of tin coating or, more exactly, the amount of tin used to produce the given unit or base box of plate. Coke tin plate has always designated the plate produced with the lowest amount of tin and formerly was called Cokes or Common Cokes. In ascending weight of coating, the various grades were Common Cokes, Standard Cokes, Best Cokes, and Kanners Special. Charcoal tin plate carries still heavier coatings including 1A and 2A.

CONT

Terms, charcoal plate and coke plate, which in last century described quality of iron used as a base metal, have now come to be applied to tin plate of certain coating thickness. Amount of coating on coke plates is generally between 1. 24 and 2. 5 pounds per base box-on charcoal plates between 3 pounds and 5 pounds per base box. For roofing applications, heavier charcoal weight coatings have always been preferred. Common cokes, 1. 25 lb/base box. Standard cokes, 1. 50 lb/base box; Best cokes, 1. 70 lb/base box. "Kanners" special cokes, 2. 0 lb/base box.... Weight of coating on an electrolytic plate is a measurement of amount of coating on both sides of sheet, expressed in grams per square meter. Prior to adoption of this system, a "pot yield" method was used. The coating designation numbers are a hold over from this earlier system.

OBS

coke; common coke: Terms usually used in the plural ("cokes"; "common cokes").

DEF

A method for the differential staining of bacteria by treatment with a watery solution of iodine and the iodide of potassium after staining with a triphenylmethane dye (as crystal violet).

CONT

The Gram staining method ... is one of the most important staining techniques in microbiology. It is almost always the first test performed for the identification of bacteria ... The microorganisms that retain the crystal violet-iodine complex appear purple brown under microscopic examination [and] are commonly classified as gram positive ... Others that are not stained by crystal violet are referred to as gram negative.

Método de tinción diferencial de bacterias; los frotis se fijan a la llama, se tiñen con una solución de violeta cristal, se trata con solución de yodo, se lavan, se decoloran y luego se colorean por contraste con safranina O. Los microorganismos grampositivos se tiñen de negro violáceo y los gramnegativos de rosado; es útil en taxonomía e identificación bacteriana y también para indicar diferencias fundamentales en la estructura de la pared celular.

Microwave Digestion : the preferred method for dissolving most samples in acid for analysis by AA [atomic absorption]. The method uses a closed Teflon container into which 5 to 10 mL of acid and approximately 0. 5 grams of sample are subjected to an increasing microwave field for periods up to an hour. The high pressure and temperature inside the container rapidly dissolves most samples and no volatile analytes are lost since the container is sealed.

Coating weights : Terne coating is applied by hot-dip method, where sheets are passed through a bath and rollers remove excess coating by a squeezing action. Coating thickness on "short terne" plate is expressed in pounds per double base box.(A surface area of 871. 12 square feet.) Generally 3 coating weights are available. Coating thickness on "long terne" is generally expressed in grams per square metres.

Caractéristiques mécaniques des tôles plombées [...] Revêtement. Il doit contenir 10 à 50 % d'étain selon la norme française NF A 36-330. [...] La masse du revêtement, masse globale sur les deux faces du produit, peut être déterminée par pesée avant et après dissolution du revêtement dans une solution [...] Trois valeurs moyennes minimales (g/cm²) de la masse du revêtement (double face) sont spécifiées : P75, P100 ou P120 qui peuvent prendre respectivement deux valeurs 60 ou 75, 75 ou 100, 90 ou 120 g/m² selon que le contrôle à lieu sur un ou trois prélèvements. Une masse du revêtement de 100 g/m² double face correspond approximativement à une épaisseur de 5 micromètres sur chaque face.

CONT

L'appréciation d'un fer blanc est caractérisée d'une part par l'épaisseur et la composition de l'acier de base et, d'autre part, par le taux d'étamage. En France, celui-ci représente la quantité d'étain déposée par unité de surface de feuille sur les deux faces, exprimée en grammes par mètre carré (taux courants : 27 g, 33 g, 40 g, 49 g). En Angleterre, le poids [sic : masse] du revêtement d'étain est exprimé en onces par basis box et aux États-Unis en livres par base box (le «basis box» ou «base box» étant une unité de surface, utilisée dans l'industrie du fer blanc, et qui équivaut à 40.465 m² de surface étamée).

OBS

taux d'étamage : ce terme se rapporte en réalité à l'expression de la masse du revêtement, mais peut néanmoins servir de solution de traduction, selon le contexte.

Coating weights : Pure tin coating on a hot-dip tin plate is mechanically distributed over sheet surface by tinning rolls. Due to nature of this tinning operation and elevated temperature of metal it is not possible to control, within close limits, tin coating weight. For these and other reasons, coating is measured and described by "tin pot yield" method. Total weight(in pounds) of tin consumed in manufacture of one base box, is pot yield. Terms, charcoal plate and coke plate, which in last century described quality of iron used as a base metal, have now come to be applied to tin plate of certain coating thickness. Amount of coating on coke plates is generally between 1. 24 and 2. 5 pounds per base box-on charcoal plates between 3 pounds and 5 pounds per base box. For roofing applications, heavier charcoal weight coatings have always been preferred. Common cokes, 1. 25 lb/base box. Standard cokes, 1. 50 lb/base box; Best cokes, 1. 70 lb/base box. "Kanners" special cokes, 2. 0 lb/base box.... Weight of coating on an electrolytic plate is a measurement of amount of coating on both sides of sheet, expressed in grams per square meter. Prior to adoption of this system, a "pot yield" method was used. The coating designation numbers are a hold over from this earlier system.

The mass of a unit of paper or board determined by the standard method of test. It is expressed in grams per square metre. [Definition standardized by ISO. ]

CONT

In the past, basis weight has always been based upon the weight of 1000 (or 500) sheets of a designated size which varied according to the grade. Grammage simplifies calculation because all grades are based on one sheet measuring one square metre. Grammage is specified as "grams per square metre" (g/m²).
