This document specifies the product characteristics, laboratory test methods, the way of expressing results and the relevant procedures for assessment and verification of the constancy of performance, for preformed road markings (namely, marking tapes and preformed markings) of types I and II (structured and non-structured) to be used for permanent road markings, in circulation areas.

This document does not cover:

— hot applied thermoplastics, even if commercialized in the form of sheets or on rolls, which requires the addition of drop-on materials to build up the road marking on the field site. Those products are considered to be duly covered by EN 1871:2020;

— preformed road markings for temporary use.

(1)P This document gives design requirements for cold-formed trapezoidal aluminium sheeting. It applies to cold-formed aluminium products made from hot rolled or cold rolled sheet or strip that have been cold-formed by such processes as cold-rolled forming or press-breaking.

NOTE 1 The rules in this part complement the rules in other parts of EN 1999-1.

NOTE 2 The execution of aluminium structures made of cold-formed structures for roof, ceiling, floor and wall applications is covered in EN 1090-5.

(2) This document gives methods for stressed-skin design using aluminium sheeting as a structural diaphragm.

(3) This document does not apply to cold-formed aluminium profiles like C- and Z- profiles nor cold-formed and welded circular or rectangular hollow sections.

(4) This document gives methods for design by calculation and for design assisted by testing. The methods for the design by calculation apply only within stated ranges of material properties and geometrical properties for which sufficient experience and test evidence is available. These limitations do not apply to design by testing.

(5) This document does not cover load arrangement for loads during execution and maintenance.

(1) EN 1999-1-5 applies to the structural design of aluminium structures, stiffened and unstiffened, that have the form of a shell of revolution or of a round panel in monocoque structures.

(2) EN 1999-1-5 covers additional provisions to those given in the relevant parts of EN 1999 for design of aluminium structures.

NOTE Supplementary information for certain types of shells is given in EN 1993-1-6 and the relevant application parts which include:

— Part 3-1 for towers and masts;

— Part 3-2 for chimneys;

— Part 4-1 for silos;

— Part 4-2 for tanks;

— Part 4-3 for pipelines.

(4) The provisions in EN 1999-1-5 apply to axisymmetric shells (cylinders, cones, spheres) and associated circular or annular plates, beam section rings and stringer stiffeners, where they form part of the complete structure.

(5) Single shell panels (cylindrical, conical or spherical) are not explicitly covered by EN 1999-1-5. However, the provisions can be applicable if the appropriate boundary conditions are duly taken into account.

(6) Types of shell walls covered in EN 1999-1-5 can be (see Figure 1.1):

— shell wall constructed from flat rolled sheet with adjacent plates connected with butt welds, termed ‘isotropic’;

— shell wall with lap joints formed by connecting adjacent plates with overlapping sections, termed lap-jointed;

— shell wall with stiffeners attached to the outside, termed ‘externally stiffened’ irrespective of the spacing of stiffeners;

— shell wall with the corrugations running up the meridian, termed ‘axially corrugated’;

— shell wall constructed from corrugated sheets with the corrugations running around the shell circumference, termed ‘circumferentially corrugated’.

(7) The provisions of EN 1999-1-5 are intended to be applied within the temperature range defined in EN 1999-1-1. The maximum temperature is restricted so that the influence of creep can be neglected. For structures subject to elevated temperatures associated with fire see EN 1999-1-2.

(8) EN 1999-1-5 does not cover the aspect of leakage.

TThis document specifies the characteristics of pipes made from polyethylene (PE) for buried and above ground applications, intended for the conveyance of water for human consumption, raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes.
NOTE 1 For PE components intended for the conveyance of water for human consumption and raw water prior to treatment attention is drawn to 6.3 of this document. Components manufactured for water for general purposes, drainage and sewerage are possibly not suitable for water supply for human consumption.
For use in contaminated soils special consideration is taken for pipes intended for the transport of water intended for human consumption or raw water prior to treatment.
NOTE 2 Pipes constructions including barrier layers are not covered by this document. ISO 21004 provides an alternative solution for use in contaminated soils [9].
It also specifies the test parameters for the test methods referred to in this document.
In conjunction with Part 1 and Parts 3 to 5 of EN 12201, it is applicable to PE pipes, their joints and to joints with components of PE and other materials intended to be used under the following conditions:
a) allowable operating pressure, PFA, up to 25 bar 1);
b) an operating temperature of 20 °C as a reference temperature;
c) buried in the ground;
d) sea outfalls;
e) laid in water;
f) above ground, including pipes suspended below bridges.
NOTE 3 For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see prEN 12201-1:2021, Annex A
EN 12201 series covers a range of allowable operating pressures and gives requirements concerning colours.
This document specifies three types of pipe:
— PE pipes (outside diameter dn) including any identification stripes;
— PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe (total outside diameter dn) as specified in Annex B, where all layers have the same MRS rating. A coextruded pipe made of a combination of PE 100 and PE 100-RC layers are regarded as PE 100 and marked accordingly.
— PE pipes (outside diameter dn) with a peelable, contiguous thermoplastics additional layer on the outside of the pipe (‘coated pipe’) as specified in Annex C.
NOTE 4 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes.
1) 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

NOTE 5 Assessment of the resistance to slow crack growth of the PE pipe compound used for the manufacture of products to this document is required in accordance with prEN 12201-1:2021, Table 2.
