This standard deals with the equipment requirements, execution and reporting of field vane tests for the measurement of peak and remoulded vane shear strength together with the sensitivity of fine-grained soils. In addition, post-peak shear strength behaviour can be evaluated. Two types of field vane test are described; the ordinary field vane test (FVT) and the fast field vane test (FVT-F).

The uncertainties of the vane test result are described in Annex C.

NOTE 1   This part of ISO 22476 fulfils the requirements for field vane tests as part of the geotechnical investigation and testing according to EN 1997-1 and EN 1997-2

NOTE 2   This part of ISO 22476 covers onshore and nearshore field vane testing

This document is intended to be used

—    by buyers or commissioners of conservation work (e.g. custodians, public or private individuals, collecting institutions, conservation specialists, conservation funding organisations etc.), and

—    by those individuals and enterprises seeking to carry out conservation work.

It is not intended to be used by institutional custodians as a means of directing work to their own staff.

NOTE          In this document, the term “object” is used for object, objects and collections.

This document specifies a visual method of determining the amount and components of coarse foreign matter in reclaimed asphalt. A method for determining the amount and components of finer foreign matter in reclaimed asphalt is given in Annex A. This method does not completely categorize the foreign matter that can occur in asphalt.

NOTE 1       For the use of reclaimed asphalt in asphalt mixtures, it is important to know the components in the reclaimed asphalt and to what extent coarse foreign matter is present that can influence the properties of the asphalt mix.

NOTE 2       The method is not intended to categorize all foreign materials but rather to ensure that the amount of coarse foreign materials are minimized.

This document specifies the method to be used to verify the mechanical performance of the bonded glazing for doors, windows and curtain walling (see examples in Annex A) and its durability. The bonding covered is only that between the glass and the metal surface.

NOTE 1       Bonded glazing was formerly known as structural sealant glazing SSGS.

This document covers bonded glazing incorporated into the product construction works as follows:

—    either vertically; or

—    up to 83° from the vertical (positive slope); or

—    up to 15° from the vertical onto the building face (negative slope).

NOTE 2       A wall has a positive slope if its outer surface faces upwards.

NOTE 3       Specific additional safety provisions can apply nationally.

This document gives information to the manufacturer to comply with requirements regarding design, factory production control and assembly rules.

The parts concerned in the testing are the metal surface (anodized and coated aluminium, stainless steel), the glass coated or not which shall be bonded, the bonding sealant and mechanical restraints when required.

This document does not apply to:

—    other surfaces materials;

—    direct glazing;

—    glass-to-glass bonding and edge seal of insulating glass units (which are covered by EN 13022‑1 and EN 1279‑5);

—    adhesive tapes.

This document specifies a method for determining the rebound number of an area of hardened concrete using a spring-driven hammer.

NOTE 1       The rebound number determined by this method can be used to assess the uniformity of concrete in situ, to delineate zones or areas of poor quality or deteriorated concrete in structures.

NOTE 2       The test method is not intended as an alternative for the compressive strength determination of concrete (EN 12390‑3), but with suitable correlation, it can provide an estimate of in situ compressive strength. For the assessment of in situ compressive strength, see EN 13791.

NOTE 3       The hammer can be used for comparative testing, referenced against a concrete with known strength or against a concrete which has been shown that it has come from a defined volume of concrete with a population verified as conforming to a particular strength class.

This document specifies performance requirements and test methods for the classification of the bullet-resistance of glass (consisting of one or more layers of glass) and glass/plastic composites.

NOTE 1       The term “bullet-resistant glazing” applies to products that have the obvious characteristics of glass, but it is understood to include also laminated products of glass and plastics and in some saces, insulating glass units.

This document applies to:

—    attack by handguns, rifles and shotguns;

—    glazing in buildings, for interior and exterior use;

—    the glazing product itself, assuming proper fixing;

NOTE 2       The protection provided by bullet-resistant glazing depends not only on the product itself, but also upon the design and fixing of the glass.

This document specifies the method for the determination of the secant modulus of elasticity in compression of hardened concrete on test specimens which can be cast or taken from a structure.

The test method allows the determination of two secant moduli of elasticity: the initial modulus, EC,0 measured at first loading and the stabilized modulus, EC,S measured after three loading cycles.

Two different test methods are given. The first (Method A) is for determination of both initial and stabilized moduli, the second (Method B) is for determination of stabilized modulus only.
