This document specifies fundamental radiographic techniques which enable repeatable results to be obtained economically. This document applies to the X-ray radiographic examination of heated tool, electrofusion, extrusion and hot gas joints in plastics materials. It applies to joints in single wall pipes and plates with a range of thicknesses from 5 mm to 100 mm. It only applies to pipes containing air or other gases at the time of X-ray testing. This document does not specify acceptance levels of the indications.

To allow ductile iron pipe manufacturers and users of the product to apply TMPO linings and thereby comply with the relevant requirements of EN 545, EN 545, EN 969. This demonstrates innovation according to Annex I, by the use of non-traditional coating systems offering environmental and economic benefits. The TMPO linings meet the criteria expressed in EN 14901, except for those pertinent to fusion bonded epoxy chemistry. The linings are being used in other parts of the world eg Australia and New Zealand and have been incorporated in the recent AWWA C116/A21.16-15 publication. The current status for TMPO linings in EU amounts to a barrier to trade and does not support SME’s involved in the manufacture, lining and application of the material that offers human health benefits, as highlighted in the Annex I and II.

This part of the EN 13523 series specifies two methods for determining the numerical evaluation of the adhesion of strippable films which have previously been applied to an organic coating on a metallic substrate. Samples can be tested irrespective of whether the strippable film has been applied in the laboratory or on the production line. NOTE Method 1 is preferred for films with adhesive and method 2 for films without adhesive.

This part of EN 13523 specifies the panel design and describes the procedure for determining the resistance to outdoor exposure of an organic coating on a metallic substrate.

This part of the EN 13523 series specifies the procedure for evaluating the degree of curing by assessing the resistance of a cured organic coating film, applied on a metallic substrate, to a specified organic solvent.

This European Standard defines the requirements and test methods for factory applied epoxy coatings (fusion bonded powder or liquid two-pack) used for the corrosion protection of ductile iron fittings and accessories conforming to EN 545, EN 598, EN 969, EN 12842, EN 14525, for: - conveying water (e.g. potable water) at operating temperature up to 50 °C excluding frost; or - conveying waste water at operating temperature up to 45 °C excluding frost; or - conveying gas at operating temperature up to 50 °C; - suitable for external environments, i.e. soils, waters and atmospheres of all common corrosion loads, characterized in EN 545:2010, D.2.3.
