The revision of this standard contains no major changes, only minor corrections and clarifications of an editorial nature. This European Standard is one of a series of standards which specify test methods for determining dimensions and properties of thermal insulating materials and products. It supports a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through the consideration of the essential requirements. This European Standard has been drafted for applications in buildings, but it may also be used in other areas where it is relevant. This European test standard is one of the following group of interrelated standards on test methods for determining dimensions and properties of thermal insulation materials and products, all of which fall within the scope of CEN/TC 88:  EN 822, Thermal insulating products for building applications — Determination of length and width  EN 823, Thermal insulating products for building applications — Determination of thickness  EN 824, Thermal insulating products for building applications — Determination of squareness  EN 825, Thermal insulating products for building applications — Determination of flatness  EN 826, Thermal insulating products for building applications — Determination of compression behaviour  EN 1602, Thermal insulating products for building applications — Determination of the apparent density  EN 1603, Thermal insulating products for building applications — Determination of dimensional stability under constant normal laboratory conditions (23 °C/50 % relative humidity)  EN 1604, Thermal insulating products for building applications — Determination of dimensional stability under specified temperature and humidity conditions  EN 1605, Thermal insulating products for building applications — Determination of deformation under specified compressive load and temperature conditions  EN 1606, Thermal insulating products for building applications — Determination of compressive creep SIST EN 1606:2013

is the original product thickness; dS is the thickness of the specimen; dL

Key dL reference value for deformation measurements t time 1 'dead weight' of the loading device (< 10 % of the smallest stress chosen for the creep test) 2 load applied in the compressive creep test 3 deformation curve In this figure, dL is used as a reference value for deformation measurements. If dS is used as the reference value, the figure can be used, omitting the column for dL (see 7.3). Figure 1 — Illustration of the different thicknesses and deformations 4 Principle The compressive creep is determined by measuring the increase in deformation of a specimen under constant compressive stress and specified conditions of temperature, humidity and time.

The movable platen shall be guided in such a manner as to be self-aligning. The platens shall be capable of being loaded smoothly and without distortion so that, during the test, the static stress does not change by more than ± 5 %
