Certification mark for aluminium transport boxes

Certification mark for aluminium transport boxes

  

 

Scope:

The certification mark applies to aluminium transport boxes and their ability to withstand the ingress of dust (dust-tight) and water in case of temporary immersion (testing of compliance with protection class rating IP65)

Basis of certification:

The certification mark is awarded within the framework of voluntary testing and certification. Testing is based on the EN 60529 and the PPP 53319B standard. These standards govern the basic safety regulations and test criteria for aluminium transport boxes and/or enclosures. The EN 60529 defines the requirements and test methods for the respective IP code (testing of compliance with the protection class rating).



The objective is to protect the equipment inside the enclosure/transport box from the harmful impacts of dust and water. In addition, the basic requirements set forth in DGUV (German Social Accident Insurance standard) 108-007 for the design and exterior safety of the boxes (pointed or sharp edges, points involving crushing and shearing hazards), stability, safety against falling out or down (stackability) and safety against breaking.

Key Words of the certification mark:

  • IP65

    The IP protection class system rates the degree of protection offered by an enclosure for electrical equipment against solids (e.g. dust) and liquids. The characteristic numeral 6 stands for “dust tight”, meaning that there will be no ingress of dust.The characteristic numeral 5 stands for “water jets”, i.e. a powerful water jet directed against the enclosure from any direction must not have any harmful effects.

  • Dust tight

    Users can use the tested transport boxes to store operating equipment. The boxes simultaneously provide protection against ingress of dust to the boxes. To ensure this protection, the box is subjected to an IP classification test in a dust chamber according to Figure 2 of the EN 60529 (degrees of protection provided by enclosures).

    In this test the boxes (depending on their volumes) are stored for a maximum of eight hours in the chamber with a negative pressure of 20 millibar (mbar) inside the enclosure. After the test the boxes are examined for dust Ingress.

  • Jetting water proof

    Users can apply the tested transport boxes to store operating equipment. The boxes simultaneously provide protection against the ingress of water into the boxes. To ensure said protection, protection class testing is carried out using a jet nozzle. In testing, a water jet is sprayed against the surface of the boxes from all directions at a distance between 2.5 and 3 m. The volume flow is 12.5 l/min. The test duration per square metre of box surface is 1 min. with a minimum test duration of 3 minutes. After testing, the boxes are examined for water ingress.

  • Production monitored

    Periodic surveillance and/or monitoring of the manufacture of a product constitutes the basic premise for certification that includes the award of a certification mark. Certification always requires product testing and regular factory inspections.

    As a third-party expert organisation, TÜV SÜD Product Service verifies that the manufacturer is able to maintain consistent quality in line with the requirements throughout high-volume production and has established the necessary quality system, including incoming goods inspections, lists of materials and final product testing.

    In addition, calibration of the necessary measuring and monitoring equipment must be ensured. Surveillance and/or monitoring covers the testing of safety-critical components and other materials used. If unauthorised changes are made to the product, the certificate will become invalid and the TÜV SÜD certification mark may no longer be used.

  • Safety tested

    The voluntary certification mark with the statement “Safety tested” is issued for products, indicating that the product was tested and certified by the independent third-party organisation of TÜV SÜD Product Service for conformity with the essential technical safety requirements.
