This document establishes a system of designation for polyoxymethylene (POM) thermoplastic materials, which can be used as the basis for specifications.

The types of polyoxymethylene (POM) materials are differentiated from each other by a classification system based on appropriate levels of the following designatory properties:

a) melt mass-flow rate or melt volume-flow rate;

b) tensile modulus,

and on information about basic polymer parameters, intended application, method of processing, important properties, additives, colorants, fillers and reinforcing materials.

This document is applicable to all polyoxymethylene homopolymers and to copolymers of polyoxymethylene and blends of polymers containing polyoxymethylene.

It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified and modified by colorants, additives, fillers, etc.

It is not intended to imply that materials having the same designation necessarily give the same performance. This document does not provide engineering data, performance data or data on processing conditions which can be required to specify materials for particular end-use applications. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in the relevant International Standards.

This document specifies a method for the quantitative determination of the sum of short-chain polychlorinated n-alkanes also known as short-chain polychlorinated paraffins (SCCPs) in the carbon bond range n-C10 to n-C13 inclusive, in mixtures with chlorine mass fractions ("contents") between 50 % and 67 %, including approximately 6 000 of approximately 8 000 congeners.

This method is applicable to the determination of the sum of SCCPs in unfiltered surface water, ground water, drinking water and waste water using gas chromatography-mass spectrometry with electron capture negative ionization (GC-ECNI-MS).

Depending on the capability of the GC-ECNI-MS instrument the concentration range of the method is from 0,1 μg/l or lower to 10 μg/l. Depending on the waste water matrix, the lowest detectable concentration is estimated to be > 0,1 μg/l.

This document specifies general rules for design, manufacturing, protection, transport, storage, installation, and inspection of structural bearings for use in bridges and other structures, e.g. buildings.

This document does not give rules for:

— bearings subjected to uplift forces;

— bearings for the specific moving function of moveable bridges (for example bascule bridges, lift bridges, etc.);

— concrete hinges;

— levelling pads.

It can be used for guidance in the case of temporary bearings and the principles can be applied to the design and manufacture of other types of structural bearings not included in this European Standard.

If bearings are used as or as part of anti-seismic devices with the aim of modifying the dynamic response of the structure, EN 15129 also applies.

This document will be used in conjunction with the other relevant parts of the prEN 1337 series.

It is applicable to:

— flat and curved sliding elements made of polytetrafluoroethylene (PTFE), lubricant and austenitic steel or chromium plated surfaces or anodized aluminium,

— sliding elements for guides made of PTFE or composite bearing materials, lubricant and austenitic steel,

— PTFE surfaces with a circumscribing circle diameter of single or multiple PTFE sheets larger than 75 mm and smaller than 1 500 mm,

— PTFE surface temperatures between –35 °C and +50 °C and

— steel to steel sliding surfaces.

Additional requirements for curved sliding elements used in spherical and cylindrical PTFE bearings are covered by prEN 1337-7:2018.
Sliding elements for use as temporary devices during construction, for example during launching of the superstructure, and sliding elements not permanently in contact, other than guides, are not covered within this document, because the required performance and conditions may deviate considerably.
This document will be used in conjunction with the relevant parts of this standard series.

This International Standard specifies technical requirements for direct adhesive bonding of glazing materials into recesses forming part of the structure of the ship of glazed openings on a Large Yacht (as defined in Part 1). This also includes technical requirements for direct adhesive bonding into a frame that is fastened to the structure of the ship.

It is limited to the bonding of independent glazed openings, where the bonded joint is designed to withstand local loads (from external loads coming from weather and sea conditions, internal impact loads from accidental passenger or cargo shifting, wind suction and accelerations due to ship motions).

Requirements for bonding of glazing openings where the glazing material is subjected to bending moments and shear forces from global ship motions (bending, shear force and torsion) are outside the scope of this standard.

Additionally this standard is limited to bonding that exhibits linear elastic behaviour, and excludes rigid bonding and nonlinear elastic bonding. Bonding that is considered outside the scope of the standard should be considered on a case by case basis.

This standard has 3 parts of which this is part 2. The other parts are;

Part 1 Design Criteria, materials, framing, and testing of independent glazed openings

Part 3 Quality and Inspection
