It supersedes BS EN which is withdrawn. A list of organizations represented on this committee can be obtained on request to its secretary. BS EN contains significant changes from BS EN , in terms of its structure, the applications covered, and the physical requirements. The standard now refers to the production of construction products e. The standard has been divided into two self contained families, covering Air lime and Lime with hydraulic properties and their subfamilies listed below.

A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract.

Users are responsible for its correct application. This document supersedes EN This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January , and conflicting national standards shall be withdrawn at the latest by January Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

The standard has been revised due to a normative reference to mercury thermometers. The changes involve mainly the text in 6. This draft European standard EN consists of the following parts under the general title Bitumen and bituminous binders — Determination of the paraffin wax content — Part 1: Method by distillation; — Part 2: Method by extraction. The changes introduced mainly involve the revision of the text in 6. Aqueous bituminous binders, fluxed or cut-back anhydrous binders, and modified binders, whatever their consistency, are not within the scope of the present test method.

This European standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For dated references, only the edition cited applies.

For undated references, the latest edition of the referenced document including any amendments applies. EN 58, Bitumen and bituminous binders - Sampling bituminous binders EN , Bitumen and bituminous binders - Characterization of perceptible properties EN , Bitumen and bituminous binders - Preparation of test samples EN ISO , Water for analytical laboratory use - Specification and test methods ISO ISO , Laboratory glassware — Interchangeable conical ground joints 3 Terms and definitions For the purposes of this document, the following term and definition applies.

NOTE A cryostat with a cooling effect equivalent to that of solid carbon dioxide can be used. The temperature measuring devices employed shall be calibrated regularly. A jacketed funnel with similar dimensions, connected to the cooling bath, is also allowed.

Take all necessary safety precautions and ensure that the test sample is representative of the laboratory sample from which it is taken see EN The laboratory sample shall be taken in accordance with EN Prepare the test sample in accordance with EN Heat the distillation flask with a laboratory burner with a soft flame, approximately mm high, without a flame cone that has just ceased to be luminous in such a way that the first distillate drop falls down after 3 min to 4 min.

Fit the sheet metal guard ring see 6. Ensure that the vapours produced during distillation are being condensed by weighing, to the nearest 10 mg, the Erlenmeyer flask 6.

The rate of distillation shall remain visible and capable of being checked. Continue heating without adjusting the laboratory burner flame, until the distillation rate slows and no drop falls from the outlet tube over a period of 10 s or after 14 min from the start of distillation.

Continue heating for a further min with a completely non-luminous roaring flame until the flask glows red. Complete the distillation in a maximum of 15 min.

Do not transfer the condensate left in the outlet tube after distillation to the distillation receiver.

PY - Y1 - N2 - Natural hydraulic lime NHL binders consist mainly of portlandite, reactive silicates, and aluminates formed from the reaction of crushed limestone, containing clays or other impurities, during calcination. By their nature, these binders have a variable chemical and mineral composition, depending on thegeographical location of the limestone extraction initial composition and the manufacturing process. The NHL classification, as specified in BS EN , does not consistently give a representative indication of the properties of mortars made with particularNHL binders, because different limes in the same classification often exhibit very different properties and behaviour, thereby hindering the ease of userspecification for mortars. A representative selection of binders was characterised using calorimetric analysis, X-ray diffraction, X-ray fluorescence, and particle size analysis. The varying proportions of reactive mineral phases between the limes were related to the kinetics of the hydraulic reaction of the NHL binders and their chemical and physical properties. A relationship has been established between the chemical and physical properties of the binders and the NHLcharacteristics.
