1.1 This practice covers the procedures for testing theperformance of ultraviolet A (UV-A)，light emitting diode(LED) lamps used in fluorescent penetrant and fluorescentmagnetic particle testing (see Guides E709 and E2297,andPractices E165/E165M, E1208,E1209,E1210,E1219,E1417/E1417M and E1444).2 This specification also includes report-ing and performance requirements for UV-A LED lamps.
1.2 These tests are intended to be performed only by themanufacturer to certify performance of specific lamp models(housing，filter，diodes，electronic circuit design,opticalelements, cooling system, and power supply combination) andalso includes limited acceptance tests for individual lampsdelivered to the user. This test procedure is not intended to beutilized by the end user.
1.3 This practice is only applicable for UV-A LED lampsused in the examination process.This practice is not applicableto mercury vapor，gas-discharge，arc or luminescent (fluores-cent) lamps or light guides (for example, borescope lightsources).
1.4 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.
1.5 This standard does not purport to address all of thesafety concerns，if any,associated with its use. It is the

BS EN 12697-7:2022EN 12697-7:2022(E) Bituminous mixtures —Test methods Part 7: Determination of the bulk density of bituminous specimens by gamma rays
1 Scope
This document specifies a method for measuring the bulk density of pavement mixtures using atransmission-type gamma radiation test bench.
This method applies to cylindrical specimens or parallelepipedal blocks, prepared in a laboratory or cutfrom a pavement.The thickness and the mass absorption coefficient, which is a function of the chemicalcomposition, are known. The thickness of the specimen body traversed by the radiation is between30 mm and 300 mm.
The method cannot be applied to materials containing slags, with variable metal content or chemicalcomposition.
NOTE
Material containing metal or chemical compositions can affect the absorption of gamma rays.

0lntroduction
This International Standard consolidates the information givenin lSO 1028 and lSO 2636,and in so doing, supersedes them.
Charts are widely used to depict various types of informationprocessing problems and their means of solution. This Inter-national Standard does not restrict their use to the particularapplications exemplified herein.
ln-house rules may have to be devised to suit tho procoss ordata specification being considered. However，there areguiding principles which,if followed,will enhance readabilityand expedite cross-reference to the text.
Charts consist of symbols having a given signification, brief ex-planatory text,and connecting lines.This International Stan-dard does not deal with the wording of the text. Nevertheless,each symbol relates to an unambiguous and meaningful name(unabbreviated if possible) which is consistentthrough-out the documentation.
Charts may be used at various levels of detail; the number oflevels depending on the size and complexity of the informationprocessing problem.The level of detail should be such that thevarious parts and the interrelationship between the parts arecomprehensible as a whole.
Typically there will be a chart of the whole system showing themain constituont parts and this will form the top of a hierarchyof charts; each lower level providing a more detailed descrip-tion of one or more parts shown on the next higher level chart.
