Certification & Compliance of Equipment

Calibration & Compliance Testing

Calibration & Compliance Testing including Verification is required by various standards, Codes of Practice, Acts and Legislation ie EEA, ASTM, IEC, AS & NZS etc on a wide variety of  Meters, Personal Protective Equipment and Vehicles, in order to ensure they remain safe and are providing the level of protection that the worker requires.

HV & LV Testing

Electrical Safety Products and Personal Protective Equipment cannot be visually confirmed as providing the required level of protection, so they are required to be electrically tested at regular intervals to confirm if the insulation is providing adequate protection. Testing and calibration of equipment can be conducted from 2.5kV, up to 300kV to ensure the equipment is fit for purpose and providing the correct uncertainty of measurement as required.

Some equipment covered by calibration & verification includes:

  • Insulated Gloves - class 0 to 4
  • Insulated Mats - Class 0 to 4, A & B
  • Insulated Sleeves - Class 2 to 4
  • Insulated Tools
  • Torque Wrenches 
  • Guards 
  • Sticks, operating, tree trimming, phasing, proving, VDD
  • Earth sets & Jumpers
  • Portable Applicance Testing
  • Ladders
  • Harnesses
  • Lanyards
  • Lever Hoists, chains, wire ropes - proof test
  • Proximity testers
  • Phase Dectors
  • Cable Locators
  • Transformer pressure tests
  • Battery Discahrge testers
  • Clamp Meters
  • Voltage Meters
  • Clip on Clamp Meters
  • Universal Relay Testers
  • Multi function Multimeters
  • Multimeters
  • Digital Earth Resistance Testers
  • Data Loggers
  • HV Proving Units
  • RCD Testers
  • Circuit Breaker Analyser
  • Timers
  • EWP - Bucket Liners, boom electrical tests (6 monthly), AE, 5/10 year major inspections and NDT

Note: In service checks on insulating protective equipment including gloves, sleeves, mats, blankets, poles & jumper leads in accordance with specifications such as those listed below (or technically equivalent) and to demonstrate compliance with EEA:   ASTM D120, D1048, D1049, D1050, D1051, F478, F479, F496, F711 & F712

EWP AE Testing

In addition to six monthly Mechanical Inspections and any Electrical boom and liner testing, an Acoustic Emission Test is required on all mobile elevating work platform's fitted with a fibreglass boom (FRP) every 2 years.  The test involves sophisticated equipment to detect any breaks or cracks in fibres as a load is applied and withdrawn over periods of four minutes. As required by AS/NZS 4748 - Acoustic Emission Testing of Fibreglass Insulated Booms on Elevating Work Platforms, this test must be carried out at two yearly intervals or if any damage has occurred through other reasons ie an accident.

Ladder Testing

In addition to the standard requirement of HSE Act "to take all practicable steps to prevent harm", there are a number of standards  ie AS/NZS 1892 for various types of ladders; each standard details the requirements for use and testing including visual and deflection testing both of which Design Engineering can undertake.
KEEP TRACK OF YOUR COMPLIANCE DATA THROUGH OUR SECURE ONLINE CLIENT ACCESS AREA accessIble through our website orange button on every page.

All inspection and test data is recorded into our live secure database including test period, location, serial numbers and test readings. When we come to test again our unique bar code scanning will reduce the time taken to find the asset enabling us to ensure records are consistent, kept accurate and up to date - no one else does this. Our database provides a complete history of your asset, helping to take the compliance hassle out of your business.  Available to you at anytime including archived jobs via our secure client login area, this data is at your fingertips when you need it. Contact to get a login and password if required.

With these capabilities DE can offer you the most comprehensive testing and verification service available to manage your assets more efficiently - no other Company in New Zealand can offer the same level of service for Verification, Certification, Compliance & Consulting.

Remember we are mobile so can come to you or if this does not suit  then drop the equipment to any DE office located throughout NZ and we will undertake the tests in our lab facilities and return to you.
