This document specifies the procedure for the determination of coating strength, and hence of cohesive strength in a tubular coating tensile test.The test is intended to determine the tensile coating strength parallel to the spray layers (normal to the spray direction) and to identify differences in particle bond quality.The tubular coating tensile test is suitable for sprayed coatings deposited using metallic materials (not carbides and ceramics).The tubular coating tensile test is not suitable for fused sprayed coatings deposited using self fluxing alloys.The test supports quality assurance and is intended to be applied for the purpose of coating optimisation by identifying the influences of coating parameters and spray materials on the coatings's quality. Furthermore, the coating in particular for cold sprayed coatings can be compared with the characteristics of similar solid materials and the coating's quality can be assessed.This test is not recommended for thin coatings (coating thickness < 500 µm), since massive scattering of results is to be expected here. Due to the size of the specimens, it is particularly suitable to apply the tubular coating tensile test for coating processes that use a concentrated spray jet and a highly focused spray spot, as in the case of cold spraying, high velocity flame spraying (HVOF) or plasma spraying. Applying the tubular coating tensile test for coating processes that use a broad spray jet, such as flame spraying and arc spraying, may require special spraying measures, e.g. the use of a template to ensure a nearly vertical impingement angle.

This document describes a methodology for reducing the overall environmental impact through product design and development that is tailored to mechanical products as defined in 3.1. This methodology is particularly well suited to the redesign of an existing product; it can also be applied for the design of a new product provided the necessary assumptions regarding a (virtual) reference product are taken. It addresses companies which have decided to integrate an ecodesign approach to optimise environmental impacts within the product life cycle, in relation to the other product aspects, such as functionality, quality, costs, etc. It also helps to meet some requirements of ISO 14001:2015 on the integration of environmental aspects in the design of products. NOTE 1 This document targets persons who are directly involved in the design and development of mechanical products, as well as managers responsible for defining corporate policies, and decision-makers. The proposed methodology is intended to kick-start ecodesign initiatives within companies as part of a teaching and continuous improvement approach.This document also includes a template that companies can use as part of the communication on their environmental approach. This document is neither intended nor suitable to compare products (even similar) of different suppliers. This document is neither intended nor suitable for product certification purposes.NOTE 2 An example of implementation of the methodology is given in Annex D; the basic principles for the establishment of this method are given in Annex E.
