Estimated sign specification

The estimated sign, , also referred to as the e-mark or quantité estimée can be found on some prepacked products in Europe. Its use indicates that the prepackage fulfils European Union Directive 76/211/EEC, which specifies the maximum permitted tolerances in package content. The shape and dimensions of the e-mark are defined in European Union Directive 2009/34/EC.[1] The e-mark is also used on prepackages in Australia and South Africa.

The scope of the directive is limited to prepackages that have a predetermined nominal quantity of between 5 g and 10 kg or 5 ml and 10 L; is filled without the purchaser present, and where the quantity cannot be altered without opening or destroying the packing material.

The estimated sign indicates that:

The tolerable negative error is related to the nominal quantity and varies between 9 per cent on prepackages nominally 50 g or 50 ml or less, to 1.5 per cent on prepackages nominally 1 kg or 1 l 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).

The sign looks like a stylised lowercase "e" and its shape, , is precisely defined by 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 at position U+212E.

The estimated sign may be printed on a prepackage if:

Tolerable negative error[]

Absolute error tolerances.
Relative error tolerances.

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.

When using the table, the values of the tolerable negative errors shown as percentages in the table, calculated in units of weight or volume, shall be rounded up to the nearest 0.1 g or 0.1 ml.
