ASD-STAN/D 4/S 5 - Test Methods

This document specifies the monitoring of mechanical tests and inspections performed both at the material (coupon) and at the structural scale by the implementation of kinematic field measurements by digital image correlation. This document describes an in situ method for evaluating the metrological performance of an extensometer system using image correlation for the delivery of displacement fields, and by extrapolation, of deformation fields. It can be implemented prior to the actual start of the test (or inspection). It will inform of the metrological performance in testing conditions.
This document allows the metrological performance of the measuring technology to be quantified. The methodology described herein is not to be considered as a calibration step. This reference document does not exhaustively specify the constitutive elements of a generic system of Digital Image Correlation measurement. This reference does not address the measurement of 3D shapes via stereocorrelation systems.

This document provides a series of standard testing methods to determine the resistance of flat or curved surfaces against abrasion, scratch or punch under high dynamics as may occur for example by manually operating actuators or due to impacts of materials like shoes, cases, bags and other common objects of everyday’s usage inside an aircraft cabin. The method is also suitable to test the resistance of a surface against all other high dynamic strains.

This document specifies the test method for the determination of the vertical flame propagation and after flame time of non-metallic materials in part or in whole.
This test method is also used for testing non-metallic materials which have to meet the test criteria for the vertical Bunsen burner test:
a)   with a flame application time of 60 s;
b)   with a flame application time of 12 s.
It is used for evaluation of non-metallic materials or constructions used in the interiors of aerospace vehicles but also may be used in other applications as specified in applicable procurement and regulatory documents.
This standard should be used to measure and describe the properties of non-metallic materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

This document specifies the test for the determination of the resistance of non-metallic materials in part or in whole to flame and glow propagation and to flame penetration.

This document specifies the test method for the determination of the horizontal flame propagation of non-metallic materials when subjected to a small flame in part or in whole.
This test method is also used for testing non-metallic materials which have to meet the test criteria for the horizontal Bunsen burner test.

This test method defines the procedure for the determination of the curing-characteristic and glass transition temperature of non-metallic materials (e.g. preimpregnated and neat resin systems, adhesives) for aerospace use by Differential Scanning Calorimetry (DSC).
The results obtained by this method may be useful for:
-   derivation of the optimum cure cycle (only together with other test methods e.g. Tg determination)
-   assessment of the condition of the resin
-   assessment of the ageing behavior of the resin
This European Standard does not give any directions necessary to meet the health and safety requirements. It is the responsibility of the user of this European Standard to adopt appropriate health and safety precautions.

This test method defines the procedure for the estimation of the extent of cure of certain non-metallic materials (e.g. preimpregnated and neat resin systems, adhesives) for aerospace use. The extent of cure is estimated by Differential Scanning Calorimetry (DSC) measurements of uncured (reference) and cured materials. Additional evidence on the extent of cure may be gained by combining results from this method with those obtained by other techniques.

This European Standard defines the determination of density according to displacement method for metallic materials.

This European Standard defines different types of electrical conductivity reference blocks, to be used for the calibration of eddy current conductivity measuring equipment, their method of production and calibration.
It is to be used in conjunction with EN 2004-1.

This document provides a series of testing methods to determine the resistance of the digital display during general usage in an aircraft cabin. The document applies to any passive and interactive displays. It includes also dirt affinity and cleanability.
The testing methods include the determination of the durability of touchscreen surfaces, signing pads and general displays against human fingertip and hand abrasion, fingerprint and dirt affinity under the usage by humans as can occur during everyday operation inside an aircraft cabin. Additionally, the resistance against general abrasion, scratch and mar on the displays as well as the resistance study against the routine cleaning procedure conducted inside the aircraft is defined.
The test methods are also suitable to test the durability of a display surface against all low and high dynamic strains.
