DUBAI ACCREDITATION DEPARTMENT – DUBAI MUNICIPALITYFOREWORDDubai is a rapidly expanding Emirate, and the Government places great emphasis onproviding quality services. The main role of DM is to formulate the Emirate’s urban strategicplans as well as the provision of essential infrastructure, environmental and health services forthe continued development of Dubai as a modern, safe and dynamic Emirate. The DM,through its Dubai Accreditation Department (DAC) undertakes assessment andaccreditation of various Conformity Assessment Bodies (CABs) according to InternationalStandards, guidelines and world best practices.The requirements for accreditation of Inspection Bodies are basically the ISO/ IEC 17020 aswell as the criteria for performing testing and inspection according to the technical standardsdefined in the scope of accreditation by each CAB.This document DAC-Req-06 describes the requirements for accreditation of inspectionbodies working in the field of lifting equipments inspections for all types of cranes,suspended equipment, construction hoists, elevators, escalators and other man-liftingequipments under the accreditation program operated by the Dubai AccreditationDepartment (DAC) of Dubai Municipality. This accreditation program is being implementedin order to provide a means of assessing and accrediting the competence of the inspectionbodies to carry out inspections and related activities for the requirements of DubaiMunicipality pursuant to the local order 61/1991.This document should be read in conjunction with the International Standard ISO/ IEC17020:1998, General criteria for the operation of various types of inspection bodies, ILAC(International Laboratory Accreditation Cooperation) /IAF (International Accreditation Forum)joint publication IAF/ILAC A4:2004 Guidance on the Application of ISO/IEC 17020 and DACdocument DAC-Reg-01, Accreditation Requirements.DAC-Req-06 has been produced by DAC in cooperation with the Technical Committee forAccreditation of Inspection Bodies.DAC-Req-06 shall be used for accreditation of Inspection Bodies performing inspection oflifting equipment. It is also intended to assist employers to select 'competent persons' for thepurposes of The Lifting Operations and Lifting Equipment Regulations 1998 (LOLER).While accreditation will normally be an indication of the quality of services offered by theinspection bodies, it should not be regarded as a guarantee that the inspection body willalways maintain a particular level of performance. It shall not, in any way, diminish thecontractual obligation between the inspection body (IB) and its clients. It is subject torevision periodically when deemed necessary. It is the responsibility of the IB to ensure thatthe latest version of this document is available for reference and implementation.This is an official document of DAC; The Printed copy of this document shall be treated as ‘Uncontrolled’.

DUBAI ACCREDITATION DEPARTMENT – DUBAI MUNICIPALITY1 DEFINITIONSThe purpose of this section is to define the general and technical terminologythat is used throughout this document.1.1 Lifting EquipmentAny lifting machine, driven by manual or mechanical power that is able toraise, lower or suspend loads, and includes the supporting structure and allplant, equipment and gear used in connection with such a machine, butexcludes continuous mechanical handling devices (i.e. conveyors) such asbut not limited to: -i. Cranes (tower, mobile etc),ii. Wall / Pillar Cranes, Derricks, Swing Jibs and Davits,iii. Runway Beams, Monorails, All Pad Eyes, Gin Poles and Gin Wheels,iv. Winches, Hoists (air and electric), Crabs, Telfer Hoists,v. Chain Blocks, Wire Rope Pulling Machines, Pull Lifts, Trolleys,vi. Powered working Platforms,vii. Elevators and Lifts,viii. Forklifts, Self Loader and Side Booms,ix. Lifting Jacks (pneumatic or hydraulic).1.2 Lifting Accessories or Loose Gear (also known as Lifting Jackets)Any item used to connect a load to the lifting equipment but which is not initself a part of the load or the equipment, such as:i. Chains and Wire Ropes,ii. Chain, Wire Rope and Webbing Slings,iii. Rings, Links, Hooks, Shackles, Eye Bolts, Swivels, Blocks, Snatch Blocks,iv. Beam Clamps and Plate Clamps,v.

Alteration of kind of current or voltage,ix. Alteration of kind of guiding rails,x. Alteration of kind of number of landing doors.1.4 RepairA measure whereby the original state of equipment will be restored byrebuilding or exchanging parts or units. If essential parts with safety functionsare to be rebuilt or exchanged, this is considered to be a “Major Repair”. Thisis the case particularly in respect of the exchange of the following:i. Brakes,ii. Safety Gear or catching devices,iii.iv.Over-Speed Governors,Load carrying parts (e.g. anchorages, open or closed spelters sockets,primary structures etc),v. Driving mechanisms and controls.Repair also includes the replacement of a part or a complete assembly if thepart or the complete assembly is covered by a certificate for its capacity orperformance by the manufacturer of either the part/assembly or of the originalequipment.1.5 InspectionAny physical activity, related to ensuring that an item of “Lifting Equipment”, inits entirety and at a given location or environment, meets the specified designand operating Standards and is safe to operate or utilize for a specifiedperiod. This includes, but is not limited to, activities such as measuring,testing, recording, checking, analyzing, loading and charting one or morecharacteristics of the equipment.1.6 Periodic InspectionThe minimum, specified period, denoted in days, weeks, months or years,between one “Inspection” and a repeat or next “Inspection” as per Annex 2.1.7 LoadMeans any material, persons, or any combination of these that are lifted,lowered or suspended by the Lifting Equipment. The weight of the liftingaccessories including the hook block may be considered as part of the loadbeing lifted, as applicable by the relevant Standard.This is an official document of DAC; The Printed copy of this document shall be treated as ‘Uncontrolled’.

DUBAI ACCREDITATION DEPARTMENT – DUBAI MUNICIPALITY1.8 Working Load Limit (WLL)Means the maximum load (mass), which any piece of lifting equipment maylift safely in the most efficient configuration. For wire rope, chain and fiberrope slings this is in direct lift i.e. eye to eye in a straight vertical line.1.9 Safe Working Limit (SWL)Means the maximum load (mass), which any piece of lifting equipment maylift safely in a particular configuration, other than its most efficientconfiguration. e.g. for a wire rope sling choked on a square load without anycorner protection its safe working load is approximately 50% of its WLL.1.10 Proof Load TestThe application of a predetermined load excess of SWL to assess the abilityof the equipment to withstand operation requirements. This applied proof loadshall never exceed the elastic limit of the item being tested.The amount of Proof Load to be applied will vary depending upon the type ofequipment, its SWL, and the applicable Standard (refer to Annex 1).On completion of any proof load test, the “Lifting Equipment” is to be fullyinspected to ensure that the structural integrity of the equipment has not beenimpaired.1.11 The Minimum Breaking (or Failure) Load (MBL)It is the theoretical load below which a sample of the item will not break or fail,when new.1.12 Factor of Safety (FOS) or Coefficient of Utilization or Working CoefficientIt is a factor that is applied to the MBL to determine the WLL (working loadlimit). It varies with the product to take account of the susceptibility to damageand considers the type of stresses the item will withstand in normal use.Where the conditions of use are more severe than those considered by theproduct standard, the user would apply an increased FOS, so reducing thevalue of the SWL from that of the WLL.1.13 Inspection Certificates (of Lifting Equipment)All original Inspection Certificates issued by a DAC accredited IB, to indicatecompliance of lifting equipment with safety requirements and its fitness foruse, shall be a Certificate both in name, detail and format. Each certificateshall contain the minimum details as specified under section 4.6.2.A Certificate shall not be issued where the lifting equipment does not complyfully with the requirements of the relevant Standards and the requirements ofthis document.The certificate shall be signed by the authorized Inspector who has performedthe inspection, or by any other appropriate authority assigned by the IB.This is an official document of DAC; The Printed copy of this document shall be treated as ‘Uncontrolled’.
