28、ass and the manufacturers mark.8 Testing8.1 Shape and dimensions8.1.1 MeasurementIt shall be checked whether the dimensions of blocks are as specified in subclause 5.1.2.The length, width and height shall be measured using vernier calipers, and shall be determined as the arithmeticmean of two measur

29、ements. When measuring the length of tongued and grooved blocks, measurements shallbe compared with the system length.8.1.2 Expression of resultExternal dimensions shall be given to the nearest millimetre.8.2 Apparent density8.2.1 MeasurementThe apparent density shall be determined by dividing the d

30、ry mass of a block by its volume (i.e. the productof its length, width and height, measured as specified in subclause 8.1.1), with the dry mass based on the massof whole blocks or representative pieces of block dried to constant mass at 105 C.8.2.2 Expression of resultThe apparent density shall be t

31、he arithmetic mean of the individual measurements, given in kg/dm3to twodecimal places. The test report shall include both the individual values measured and the arithmetic mean.8.3 Flexural strength8.3.1 ProcedureThe flexural strength shall be determined using air-dried blocks.The block shall be pl

32、aced flat on two supports so as to be free to rotate and shall be subjected to a line loadacting centrally over a width of 20 mm over the block length, along the support axis. The span, ls, shall be takento be the length of the block less 50 mm on each side. The load shall be increased slowly and st

33、eadily at a rateof 10 N/s per second, until failure occurs.8.3.2 Expression of resultThe flexural strength, bBZ, shall be calculated as follows:MBbBZ= (1)WwherelsMB= Fmax and (2)4h b2W = (3)6whereMBis the bending moment;W is the section modulus;Fmaxis the maximum load measured;lsis the span;h is the

34、 height of the block at or near the failure location;b is the width of the block at or near the failure location.The individual values of flexural strength and the arithmetic mean shall be given in the test report in N/mm2, toone decimal place.Page 5DIN 18162 : 2000-109 Conformity assessment9.1 Gene

35、ralEach factory shall obtain possession of confirmation that the blocks produced comply with the specificationsof this standard on the basis of factory production control procedures and third-party inspection including typetesting of the blocks as set out below. The manufacturer of the blocks shall

36、seek the services of an accreditedinspection body and an accredited certification body to arrange for third party inspection including producttesting and to obtain a certificate of conformity.9.2 Factory production control9.2.1 GeneralA system of factory production control procedures shall be operat

37、ed in each factory. This shall comprisecontinual monitoring of production by the manufacturer to ensure the products meet the specifications of thisstandard.9.2.2 ProcedureAt each place of production, the manufacturer shall have at his disposal qualified personnel and the necessarymeans and equipmen

38、t. He shall appoint a party responsible for factory production control procedures at thesite.9.2.3 Constituent materials and productionDuring the production process, tests shall be carried out on constituent materials and checks shall be madeof the production. The type and scope of such tests and ch

39、ecks shall be adjusted to suit the productionconditions.9.2.4 End productsThe manufacturer shall monitor the properties of the blocks. The type, minimum scope and minimum frequencyof product testing to be carried out as part of factory production control shall be as follows:a) height: one test per d

40、ay of production on three blocks;b) dimensions, apparent density and flexural strength: one test per week of production on three blocks.Should any result prove unsatisfactory, the manufacturer shall immediately take corrective action. Productsthat do not meet the requirements shall be processed so a

41、s to preclude their confusion with products conform-ing to the standard.9.2.5 RecordsThe test results shall be recorded in clear, written form and shall be evaluated. Records of factory productioncontrol procedures shall be kept for a period of at least five years and made available to the inspectio

42、n bodyon request.9.3 Third-party inspection9.3.1 Initial inspectionPrior to the onset of routine inspections, the inspection body shall carry out the full type testing programmeusing twice the number of specimens specified for routine inspections in subclause 9.3.2, in order to establishwhether the

43、blocks conform to the standard. The inspection body also has to ascertain that the manufacturerspersonnel and equipment are such as to enable continuous, trouble-free production and factory productioncontrol.9.3.2 Routine inspectionRoutine inspections shall involve checking the factory production co

44、ntrol procedures, human resources andequipment, and product testing.Routine inspections shall be carried out at suitable intervals, but not less than twice yearly.Product testing shall be carried out on at least three blocks taken at random, and shall cover the full range ofstrength and apparent den

45、sity classes produced. The properties checked shall comprise dimensions, apparentdensity and flexural strength. If necessary to avert consequential damage, the recipient may need to be in-formed where testing of the end product gives unsatisfactory results.9.4 Confirmation of conformity9.4.1 Issue o

46、f certificate of conformityTo obtain a certificate of conformity, the following shall be submitted to the certification body:a) the report of the inspection body on the initial inspection (if performed);b) a report of the inspection body containing the results of routine inspections.The certificatio

47、n body will issue a certificate of conformity if the report from the inspection body confirms thatthe results meet the requirements of the standard and the compliance criteria.Page 6DIN 18162 : 2000-10The certificate of conformity remains valid until its withdrawal. On the basis of the reports from

48、third-partyinspection, the certification body shall regularly confirm the compliance of the blocks with this standard andshall arrange for special tests to be carried out, where appropriate.In the event of production being terminated, the manufacturer shall inform the inspection body and certificati

49、onbody accordingly. The certificate will then be immediately recalled and marked invalid by the certification body.The certificate of conformity will also be withdrawn by the certification body if:a) two years following notification of a break in production, products complying with this standard are nolonger able to be supplied,b) grave defects are repeatedly established.9.4.2 Conformity markProof of conformity of the products with the requirements specified in this standard shall take the form of acertificate of conformity issued by the certificatio
