This European Standard shall be given the status of a national standard, either by publication of
22、an identical text or by endorsement, at the latest by August 2012, and conflicting national standards shall be withdrawn at the latest by August 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be
23、 held responsible for identifying any or all such patent rights. This document supersedes EN 932-5:1999. This standard forms part of a series of standards for general properties of aggregates. Test methods for other properties of aggregates are covered by the following European Standards: EN 933, Te
24、sts for geometrical properties of aggregates; EN 1097, Tests for mechanical and physical properties of aggregates; EN 1367, Tests for thermal and weathering properties of aggregates; EN 1744, Tests for chemical properties of aggregates; EN 13179, Tests for filler aggregate used in bituminous mixture
25、s. The other parts of EN 932, Tests for general properties of aggregates are: Part 1: Methods for sampling; Part 2: Methods for reducing laboratory samples; Part 3: Procedure and terminology for simplified petrographic description; Part 6: Definitions of repeatability and reproducibility. In the bib
26、liography, reference is made to the International Organization for Legal Metrology (OIML) classification, which this standard has adopted for the purposes of establishing a frequency of calibration for balance weights. According to the CEN/CENELEC Internal Regulations, the national standards organiz
27、ations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portu

DIN EN 932-5:2012-05 EN 932-5:2012 (E) 4 1 Scope This European Standard specifies general requirements for common equipment, calibration and checking procedures and reagents for the testing of the properties
29、 of aggregates. In the case of checking, other procedures than the ones described in this standard may be used provided that appropriate working relationships with the corresponding methods described in this standard have been established. In case of dispute, the checking methods described in this s
30、tandard shall be used. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

36、ion that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish
37、 a relation for obtaining a measurement result from an indication. Note 1 to entry: A calibration may be expressed by a statement, calibration function, calibration diagram, calibration curve, or calibration table. In some cases, it may consist of an additive or multiplicative correction of the indi
38、cation with associated measurement uncertainty. Note 2 to entry: For more information, see VIM International vocabulary of basic and general terms in metrology (available on http:/www.bipm.org/ ). 3.2 checking operation of assuring either: that the results of measurements of a property (such as leng
39、th, mass, temperature or time) at selected values made by a measuring instrument, or a set of them, have not deviated from that which was measured when the equipment was last calibrated within a pre-defined tolerance; or that a property (such as rotation speed, vibration frequency) of an item, or a
40、set of items, of equipment complies with the relevant requirements for that equipment. 3.3 verification scale interval (e) for balances value, expressed in units of mass, used for the classification and verification of a balance 3.4 actual scale interval (d) value, expressed as: the difference betwe
41、en the values corresponding to two consecutive scale marks, for analogue indication, or the difference between two consecutive indicated values, for digital indication. 3.5 tolerance maximum permissible deviation from the nominal value of a measurable characteristic Note 1 to entry: In the present s
42、tandard, tolerances may be expressed either as an absolute quantity without sign or as a percentage of the nominal value of a measurable characteristic. 4 Common equipment 4.1 Tolerances 4.1.1 Manufacturing tolerances NOTE By convention, the tolerances (or limits) indicated in the aggregate test sta
43、ndards are manufacturing tolerances (or limits), if not otherwise stated. DIN EN 932-5:2012-05 EN 932-5:2012 (E) 6 4.1.1.1 Linear dimensions Where a dimension is specified with manufacturing tolerances or limits, it shall be an essential dimension. NOTE Dimensions stated without tolerances are given
44、 for guidance. 4.1.1.2 Mass Where mass is specified, the manufacturing tolerance shall be 1 % of the specified mass unless otherwise stated. 4.1.2 Working tolerances Working tolerances apply to equipment (e.g. apparatus) after being subjected to wear in use, and shall be not more than twice the manu
45、facturing tolerance unless otherwise specified. 4.2 Measuring instruments 4.2.1 General Measuring instruments shall have greater measurement accuracy than the corresponding tolerance defined in the test method. NOTE Unless stated otherwise, the measurement accuracy of the instrument used should be a
46、t least five times better than the corresponding tolerance. 4.2.2 Balances and weights Balances and weights shall be calibrated. Calibration and checking of balances and weights shall comply with 5.2.3.2 and 5.2.3.3 respectively. NOTE 1 Balances can incorporate an analogue or a digital display. The
47、balance (and weights if required) selected for a weighing shall enable the mass to be determined to the accuracy required by the test method. If calibration determines that the balance is not suitable for use across its full working range, it shall be labelled to show the upper and lower limits of usable capacity. NOTE 2 Examples of categories of balances are given in Table 1. Annex C relates these categories to most aggregate standard test methods.
