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 may also be used in other areas where it is relevant. This European test standard is one of the following group of inter-related 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 12087:2013

This European Standard specifies two options:  Method 1 - partial immersion  Method 2 - total immersion The long-term water absorption by partial immersion is intended to simulate the water absorption caused by long term water exposure. The long-term water absorption by total immersion is not directly related to the conditions on site, but has been recognised as a relevant condition of test for some products in some applications. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12085, Thermal insulating products for building applications — Determination of linear dimensions of test specimens ISO 5725-2, Accuracy (trueness and precision) of measurement methods and results — Part 2: Basic method for the determination of repeatability and reproducibility of a standard measurement method 3 Terms and definitions This European Standard contains no terms and definitions. 4 Principle
4.1 Partial immersion (method 1)
The long-term water absorption by partial immersion is determined by measuring the change in mass of a test specimen, the lower part of which is in contact with water for a period of 28 days. The excess water adhering to the surface, not absorbed by the test specimen, is removed by drainage in method 1A or taken into account by deduction of the initial water uptake in method 1B. 4.2 Total immersion (method 2)
The long term water absorption by total immersion is determined by measuring the change in mass of the test specimen, totally immersed in water, over a period of 28 days.
The excess water adhering to the surface, not absorbed by the test specimen, is removed by drainage in method 2A or taken into account by deduction of the initial water uptake in method 2B. 5 Apparatus
5.1 Balance, which allows the determination of the mass of a test specimen to 0,1 g. 5.2 Water tank, with a device for keeping the water level constant to within ± 2 mm, and a device to keep the test specimen in the required position.
