This document establishes the general principles to be adopted to minimize the effects of stray current
corrosion caused by direct-current (d.c.) on buried or immersed pipeline systems. A brief description of
alternating current (a.c.) effects is provided.
The document is intended to offer guidance for:
— the design of cathodic protection systems which may produce stray currents;
— the design of pipeline systems, or elements of pipeline systems, which are to be buried or immersed and which may be subject to stray current corrosion;
— the selection of appropriate protection or mitigation measures.
The effects of a.c. induced voltages are not dealt with in detail in this document because they are
covered in ISO 18086. General principles and guidelines are, however, provided.
Stray current corrosion can also occur internally in systems containing a conducting electrolyte e.g.
near insulating joints or high resistance pipe joints in pipelines transporting conductive fluids.
Internal corrosion risks from stray currents are not dealt with in detail in this document but principles
and measures described here can be applicable for minimizing the interference effects.
Stray currents can also cause other effects such as overheating. These other effects are not covered in
this document.
A.C. currents can induce unacceptable touch voltages on above-ground appurtenances of pipeline

This Part of EN 508 specifies requirements for self-supporting roofing products for discontinuous laying made from stainless steel sheet with or without additional metallic and/or organic coatings.
The standard establishes general characteristics, definitions, classifications and labelling for the products, together with requirements for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply before they are despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions.
The standard applies to all discontinuously laid self-supporting external profiled sheets for roofing with the exception of tiles with a surface area less than 1 m2 and produced by stamping. These profiled roof sheets are designed to keep wind, rain and snow out of the building and to transfer any resultant loads and infrequent maintenance loads to the structure.
No requirements for supporting construction, design of roof system and execution of connections and flashings are included.

1.1 This document specifies procedures for designing, preparing and using pre-cracked specimens for
investigating the susceptibility of metal to stress corrosion cracking (SCC) by means of tests conducted
under rising load or rising displacement. Tests conducted under constant load or constant displacement
are dealt with in ISO 7539-6.
The term “metal” as used in this document includes alloys.
1.2 Because of the need to confine plasticity at the crack tip, pre-cracked specimens are not suitable
for the evaluation of thin products such as sheet or wire and are generally used for thicker products
including plate, bar, and forgings. They can also be used for parts joined by welding.
1.3 Pre-cracked specimens can be stressed quantitatively with equipment for application of a
monotonically increasing load or displacement at the loading points.
1.4 A particular advantage of pre-cracked specimens is that they allow data to be acquired from which
critical defect sizes, above which stress corrosion cracking can occur, can be estimated for components
of known geometry subjected to known stresses. They also enable rates of stress corrosion crack
propagation to be determined.
1.5 A principal advantage of the test is that it takes account of the potential impact of dynamic straining
on the threshold for stress corrosion cracking.
1.6 At sufficiently low loading rates, the threshold stress intensity factor for susceptibility to stress
corrosion cracking, KISCC, determined by this method can be less than or equal to that obtained by
constant load or displacement methods and can be determined more rapidly.

This document specifies methods for the measurement of specular reflectance and specular gloss of
flat samples of anodized aluminium using geometries of 20° (Method A), 45° (Method B), 60° (Method
C) and 85° (Method D) and of specular reflectance by an additional 45° method (Method E) employing a
narrow acceptance angle.
The methods described are intended mainly for use with clear anodized surfaces. They can be used
with colour-anodized aluminium, but only with similar colours.

This document specifies procedures for the removal of corrosion products formed on metal and alloy corrosion test specimens during their exposure in corrosive environments. For the purpose of this document, the term "metals" refers to pure metals and alloys.
The specified procedures are designed to remove all corrosion products without significant removal of base metal. This allows an accurate determination of the mass loss of the metal, which occurred during exposure to the corrosive environment.
In some cases, these procedures are also applicable to metal coatings, providing the possible effects from the substrate are considered.

This draft European Standard specifies the technical delivery requirements for seamless and welded butt welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of carbon and alloy steel in two test categories which are intended for pressure purposes at room temperature, at low temperature or at elevated temperatures, and for the transmission and distribution of fluids and gases.
It specifies:
a) type of fittings;
1) type A: Butt-welding fittings with reduced pressure factor;
2) type B: Butt-welding fittings for use at full service pressure;
b) steel grades and their chemical compositions;
c) mechanical properties;
d) dimensions and tolerances;
e) requirements for inspection and testing;
f) inspection documents;
g) marking;
h) protection and packaging.
NOTE In the case of a harmonised supporting standard for materials, presumption of conformity to the ESRs is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently it is essential that the technical data stated in the material standard be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the PED are satisfied.
