manufacturer's part number and year of manufacture of the equipment

require a unique marking, including the name of the manufacturer, the country or place of manufacture, the serial number and the year of manufacture (if not part of the serial number).

This explains why investments increased as from 2001 to reach a peak in 2002, i.e. the year the new factory was set up, and then decreased until the IPs.

where and when built

The tyre must also be marked with the date of manufacture in the form of a group of four digits, the first two showing the week and the last two the year of manufacture.

the year of construction, that is the year in which the manufacturing process is completed.

The identification mark, the name and address of the manufacturer and, the year of manufacture were not indicated on the planer.

By contrast, the analysis showed that concerning the harmonised efficiency reference values for separate production of heat a distinction relating to the year of construction was not necessary as the net energy efficiency of boilers has hardly improved in the period covered by the analysis.

The year of construction is the date with which the end of the manufacturing process must coincide stricto sensu.

The review has not produced evidence to indicate that the energy efficiency of boilers has changed in the period considered, and therefore the harmonised efficiency reference values for the separate production of heat should not relate to the year of construction.

Pursuant to Article 4 of Directive 2004/8/EC the Commission is to establish harmonised efficiency reference values for separate production of electricity and heat consisting of a matrix of values differentiated by relevant factors, including year of construction and types of fuel.

Developments in the best available and economically justifiable technology which took place during the period 2006-2011 which was covered by the review, indicate that for the harmonised efficiency reference values for separate production of electricity, the distinction drawn in Decision 2007/74/EC relating to the year of construction of a cogeneration unit should not be maintained for plants that were constructed from 1 January 2006 onwards.

It should not make much difference whether an aircraft has a built-in silencer or whether its silencer is fitted subsequently: the engine noise can be measured and an assessment made of whether the aeroplane is excessively noisy or not, irrespective of the date of manufacture or the type of silencer used.

The date of manufacture in the form of a group of four digits, the first two showing the week and the last two the year of manufacture.

The marking, affixed to an "essential component of the firearm", must include the name of manufacturer, the place and the year of fabrication and the serial number.

However for cogeneration units built in 2005 or before the reference values should continue to be applied reflecting the year of construction, in order to take into account the observed developments in the best available and economically justifiable technology.

One of the parts made of plastics of the child restraint device (such as shell, impact shield, booster cushion, etc.), except the belt(s) or harness, shall be marked clearly (and indelibly) with the year of production.

Before 1 January 2000, the date of manufacture may be indicated by a group of three digits, the first two showing the week and the last one the year of manufacture.

These harmonised efficiency reference values shall apply for 10 years from the year of construction of a cogeneration unit.

, establish harmonised efficiency reference values for separate production of electricity and heat. These harmonised efficiency reference values shall consist of a matrix of values differentiated by relevant factors, including year of construction and types of fuel, and must be based on a well-documented analysis taking inter alia into account data from operational use under realistic conditions, cross-border exchange of electricity, fuel mix and climate conditions as well as applied cogeneration technologies in accordance with the principles in Annex III.
