Subject field(s)
  • Metrology and Units of Measure
  • Steel
DEF

A unit of area equivalent to 112 sheets 14 by 20 in. or 31,360 in.² (217.78 ft²).

CONT

Tin plate is now sold both on a weight per unit area basis and on a thickness basis. The old unit of area is the base box, equal to the area of 112 sheets, 14 by 20 inches, or 31 360 square inches (217.78 square feet). The new unit of thickness is the millimetre and the corresponding area designation for pricing and weight or area calculations is the SITA (System International Tin Plate Area) which equals 100 square metres or 4.9426 base boxes. ... The use of symbols to designate gage was displaced by the use of base weights (or basis weights) expressed in pounds per base box that also indicated the approximate thickness of the tin-mill product ... With the recent introduction of the metric system (SI) in production, gage is the basic unit for specification and area becomes only a derived value for commercial usage.

OBS

Tinplate sheets used to manufacture cans and boxes were originally packed into wooden boxes in order to protect the polished tin surface. Sheets cut to 35 cm X 50 cm(14 X 20 in) and of 0. 3 mm thickness weighed approx. 454 g(1 lb) and 112 were packed into a box, known as the "basis box". Variation in thickness of sheet cut to the same size would vary the weight, and larger sizes were made, although these were then called "tinned sheets". Modern production techniques favour reeling into rools for shipment, and protection with interleaving of paper or plastic where necessary.

  • Acier
CONT

Fer blanc (tin plate). [...] Suivant le procédé utilisé, l'épaisseur de la couche d'étain varie de 0,4 micron dans le fer blanc électrolytique à 20 microns dans le fer blanc au trempé. [...] 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 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

caisse de base : Selon la compagnie Stelco (à Lachine), cet équivalent français est utilisé dans l'industrie. Dans les ouvrages français, l'expression «base box» (de même que son synonyme «basis box») est laissée en anglais.

Subject field(s)
  • Tolerances and Modular Co-ordination (Construction)
  • Engineering Tests and Reliability
CONT

Determination of the effective opening size, dw, FIH. The effective opening size of a geotextile, dw, is determined by wet sieving quartz sand of known composition using modified sieving equipment. The geotextile functions as a sieve.... The test sample,(diameter 18 cm), is clamped into a sieve frame. The sand, which has a dry weight of 100 g for wovens and a dry weight of 300 g for non-wovens, is then sprinkled onto the sample. The sand is then sprayed continuously with water and sieved for 15 minutes in a modified sieve machine with a vertical amplitude of 3 mm at a frequency of 50 Hz. The sand which passes through the geotextile sample is caught on a paper filter and then analyzed with [different sieves].... The effective opening size, dw, is found from the coarsest sand fraction which has passed through the test sample and in which there is still a defined quantity in relation to the original fraction.

CONT

The third technique for determining the pore size distribution is based upon wet sieving. Again, there are several variations on the basic concept .... The FIH (Franzius Institut Hanover] method determines a parameter known as the "Wet Sieving Effective opening Size" (Dw), which is sometimes considered approximately equivalent to the 90% opening size .... However, as test results obtained by Heerten demonstrate this relationship is neither accurate nor consistent.

One of the most profitable and competitive sectors of the paper industry is the "soft" tissue market. Here, the customer pays for bulk and softness, and the producer finds himself in the happy position of being able to charge a higher price for a product which actually contains a lower weight of fiber. Naturally, there has been considerable incentive to develop proprietary low-density manufacturing techniques which will give a competitive edge; and those companies engaged in soft tissue production are reluctant to divulge their methodology.
