ISO 20471:2013 specifies requirements for high visibility clothing which is capable of visually signalling the user's presence. The high visibility clothing is intended to provide conspicuity of the wearer in any light condition when viewed by operators of vehicles or other mechanized equipment during daylight conditions and under illumination of headlights in the dark. Performance requirements are included for colour and retroreflection as well as for the minimum areas and for the placement of the materials in protective clothing.

 

This document specifies a method for instrumental analysis by equilibration-isotope ratio mass spectrometry (Eq-IRMS) of liquid, aqueous food matrices to determine ¹8O/16O isotope ratios of the water of the product. The ¹8O/¹6O isotope ratios obtained by following this document are expressed as d¹8O values relative to internationally recognised reference materials. This document does not apply to sample preparation. It is assumed that the food sample has been pre-treated as necessary and homogenised. Similarly, the interpretation of the obtained d¹8O values is not covered by this document. Following this protocol will result only in isotope delta values for the sample materials. Although other instrumental techniques can be applied to determine d¹8O values in liquid, aqueous food materials, these other techniques are not covered by this document.

 

This document describes a method for sample preparation for the determination of C, N and H isotope ratio values in different fractions (sugar and pulp) of fruit and vegetable juices and their derivatives (concentrates, nectars, beverages etc.) by Elemental Analyser-Isotope Ratio Mass Spectrometry (EA-IRMS) or Isotope Ratio Measurement-Deuterium Nuclear Magnetic Resonance Spectroscopy (irm-2H-NMR). It also covers ethanol produced by the fermentation of fruit and vegetable juices, and their derivatives. Sample measurement is not included within this document. This document does not concern the analytical methods after sample preparation, namely methods using IRMS (Isotope Ratio Mass Spectrometry) technique and isotope ratio measurement-deuterium nuclear magnetic resonance spectroscopy (irm-2H-NMR), also known as SNIF-NMR (Site-specific Natural Isotopic Fractionation by Nuclear Magnetic Resonance), used to quantify the isotopic ratios of the following nuclei: 13C/12C, 15N/14N and 2H/1H. The interpretation of the obtained isotope delta values is not covered by this document.

 

This document specifies the performance requirements of aluminium pigmented organic coatings to be applied on titanium, titanium alloys, nickel or cobalt based alloys and corrosion resistant steels. This specification does not cover electrical bonding or lightning strike applications of these coatings. Additional qualification tests will be agreed with the OEM upon qualification. NOTE These coatings are not recommended for use on non-corrosion resistant steel fasteners.

 

This document specifies the application method and quality assurance for aluminium pigmented coatings as per EN 4473 for fasteners or other parts in titanium, titanium alloys, nickel or cobalt based alloys and corrosion resisting steels.

 

1 Scope 1.1 In scope This document describes: - the fundamentals and concepts for Long Term Archiving and Retrieval of CAD 3D mechanical composite information and associated composite specific PMI; - the document structure of the EN 9300-3XX family, and the links between all these parts; - the qualification methods for long term preservation of archived composite information; more specially, principles for the validation properties and for verification of the quality of the composite information archived; - specifications for the preservation planning of archived composite information; - specific functions for administration and monitoring of CAD composite archived models; - the definition of Archive Information Packages for composite CAD data. This document establishes long term archiving requirements applicable to, but not limited to, most laminated type composite items made with composite manufacturing processes such as: - hand lay-up; - tape laying; - fibre placement; - stitched resin film infusion (SRFI); - resin transfer moulding (RTM); - vacuum-assisted resin transfer moulding (VARTM); - controlled Atmospheric Pressure Resin Infusion (CAPRI); - co-cured or co-bonded composite items; - sandwich panel composite construction; - braided layers. 1.2 Out of scope The following is outside the scope of this part of EN 9300: - multi-function advanced composite structure; - composite items made with composite manufacturing processes such as filament winding, 3D braiding, or 3D weaving; NOTE Braided parts that can be represented as layered braided sleeve material can be in scope. - injection moulded fibre reinforced thermoplastics; - other Additive Manufacturing processes such as those covered by ISO/ASTM 52900; - PMI described in EN 9300-1xx series.
