Estimated sign
Template:Short description Template:Use dmy datesTemplate:Infobox symbol
The estimated sign[1] or estimated symbol,[2] Template:Char, (officially, the ℮-mark[3] or the final EC verification mark in EU law,[4]) can be found on most prepackaged products in the European Union (EU). Its use indicates that the prepackage fulfils EU Directive 76/211/EEC,[5] which specifies the maximum permitted tolerances in package content.
The shape and dimensions of the e-mark are defined in EU Directive 2009/34/EC.[4] The e-mark is also used on prepackages in the United Kingdom,[6] Australia and South Africa.[7]Template:R/superscript It must be placed in the same field of vision as the nominal weight or volume quantity, for example, "1Script error: No such module "String".mgTemplate:Thinspace℮" or "1Script error: No such module "String".LTemplate:Thinspace℮".Script error: No such module "Unsubst".
Functions
The estimated sign indicates that:
- the average quantity of product in a batch of prepackages shall not be less than the nominal quantity stated on the label;
- the proportion of individual prepackages having a negative error greater than the tolerable negative error shall be sufficiently small for batches of prepackages to satisfy the requirements of the official reference test as specified in legislation;
- none of the prepackages marked have a negative error greater than twice the tolerable negative error (since no such prepackage may bear the sign).
The scope of the directive is limited to prepackages that have a predetermined nominal weight of between 5 g and 10 kg or volume of 5 ml and 10 L, are filled without the purchaser present, and in which the quantity cannot be altered without opening or destroying the packing material.Script error: No such module "Multiple image".
The sign looks like a stylised lowercase "e" and its shape, Template:Char, is precisely defined by the European Union Directive 2009/34/EC. It must be placed in the same field of vision as the nominal quantity. The sign has been added to the Unicode list of characters as Template:Unichar.
Tolerable negative error
Error tolerance decreases as nominal quantity increases, by alternating intervals of a given percentage error with intervals of a given amount error: these interpolate between the stepwise decreases in percentage error. The estimated sign indicates that the average quantity of product in a batch of prepackages is not less than the nominal quantity stated on the label.
The tolerable negative error is related to the nominal quantity and varies between 9 per cent on prepackages nominally 50Script error: No such module "String".g or 50Script error: No such module "String".ml or less, to 1.5 per cent on prepackages nominally 1 kilogram or 1 litre or more. The tolerable error decreases as nominal quantity increases, and is done by alternating intervals where there is a percentage error and intervals where there is a fixed error (and thus over those intervals the percentage error decreases).
