The intended function of the system considered is to convey liquids according to EN 806 (for potable water supply), EN 1264 (for heating and cooling systems), EN 12828 (for radiators), EN 12056 (for soil and waste discharge and for water traps). In case there is no application standard available, this document can also be used for other plastics piping systems such as for example for rainwater gutters, ventilation systems or electrical conduits. This document specifies product category rules of construction products as defined in and is intended to be used in conjunction with EN 15804+A2. In addition to EN 15804+A2, this document specifies: - the functional unit (consisting of pipes, fittings and ancillary components) and declared unit (consisting of pipes and/or fittings); - the system boundaries and additional mandatory modules to be declared; - the processes to be included in the installation phase; - scenarios for module A4, A5; - use conditions for the use phase (B modules); - reference service life (RSL); - end of life scenarios.

This document provides product category rules (PCR) for Type III environmental product declarations, as described in EN ISO 14025 and EN 15942, for plastic piping systems buried outside building structure and their main structural components, as specified by the list of product standards provided in Annex CC. Main structural components are: - pipes; - fittings (e.g. flange couplers, bends and reducers, valves and electrofusion fittings); - manholes and inspection chambers (where applicable, e.g. for drains and sewers). This document encompasses both pressure and non-pressure applications. The intended function of the system considered is to convey fluids according to EN 476 (for sewers, drain and surface water); EN 805 (water supply), or EN 12007 (gas supply). In case there is no application standard available, this document can also be used for other plastics piping systems such as cable conduits and surface water piping systems. This document specifies the rules for the product category of construction products as defined in and is intended to be used in conjunction with EN 15804+A2. In addition to EN 15804+A2, this document specifies: - the functional unit (consisting of pipes, fittings, manholes and inspection chambers and ancillary components) and declared unit (consisting of pipes and/or fittings and/or manholes and /or inspection chambers); - the system boundaries and additional mandatory modules to be declared; - the processes to be included in the installation phase; - scenarios for module A4, A5; - use conditions for the use phase (B modules); - reference service life (RSL); - end of life scenarios.

This International Standard describes two methods for the determination of free formaldehyde (HCHO) in polymer dispersions. The procedure has been evaluated using acrylic, acrylonitrile butadiene, carboxylated styrenebutadiene and vinyl acetate polymer dispersions. Both test methods may also be applicable to polymer dispersions of other compositions.

Method A is the preferred method for polymer dispersions with a free-formaldehyde content higher than .

Method B is recommended if lower formaldehyde contents have to be determined or arbitration analyses have to be carried out.

Both methods minimize changes in free-formaldehyde concentration that can result from changes in the physical or chemical properties of polymer dispersions.

There are no known limitations to these methods when used in the manner described.

ISO 19252:2008 specifies a method for determining the scratch properties of plastics under defined conditions. The method involves making a scratch by moving a hard instrument (scratch tip) of specified geometry under specified conditions of load and speed across the surface of a test specimen and then assessing the result.

The method is used to investigate the behaviour of specified types of specimen under the scratch conditions defined and for classifying the type of scratch of specimens within the limitations inherent in the test conditions. It can also be used to determine comparative data for different types of material by means of a so‑called scratch map in which the types of scratch behaviour for each set of test conditions of test load and test speed are determined using the basic method of constant-load testing, and also by means of the so‑called critical normal load determined using an alternative method of linearly increasing load testing.

The method is suitable for use with uncoated and unlacquered thermoplastic moulding materials and thermosetting moulding materials.

The method specifies the preferred dimensions for the test specimen and the preferred scratch-tip geometry.
