Enclosure for potentially explosive atmospheres

What is ATEX?    It is a term commonly used to describe potentially explosive atmospheres (ATmosphères EXplosibles in French) and standards for protection systems and equipment.    Two European directives, ATEX 99/92/CE and ATEX 94/9/CE, and international...

ASTA Type Test Certification

ASTA Type Test Certificates provide authoritative objective evidence that your bespoke equipment is compliant to relevant safety standards. The certificate can be used for supporting technical files related to CE Marking for the European Union. ASTA Type Test Certification is best suited for low volume or ‘bespoke’ equipment. ASTA Type Test Certification provides you with an independent...

Salt mist test

This test serves to demonstrate that under the influence of a saline atmosphere no damage (corrosion) is caused to the components of the equipment under test and no functional affections occur. This test is only performed on products which are to be installed on the open deck area. ...

Cold & Damp Heat test

Cold This test serves to demonstrate that under the influence of cold no damage is caused to the equipment under test and no permanent or temporary malfunctions occur. 5.1 Test procedure Basis: IEC publication 60068-2-1 – Test A): for products inside the ship – Test B): for products on the open deck or in cold areas. 5.2 Test conditions The functional tests are...

Design verification

Design verification is a prerequisite for all assemblies provided. It is fundamental to ensuring every assembly meets its defined design requirements. There is flexibility in the way in which this is achieved within the new standard, and some new concepts have been introduced, but the options are defined and where necessary their use is restricted and a design margin applied....

EMC Environment

Assemblies can emit and the must be immune to external  electromagnetic disturbances. IEC defines two categories    a) Environment A - relates to low-voltage non-public or industrial  networks / locations / installations including highly disturbing sources.  b) Environment B - relates to low-voltage public networks such as  domestic commercial...

Rated diversity factor

In reality all circuits within an assembly will not be called upon to carry their rated current simultaneously and continuously. Diversity is the  proportion of their rated current each circuit within a group of outgoing  circuits or all outgoing circuits within the assembly can carry,  continuously and simultaneously, without the assembly overheating. In ...

Heat Dissipation in Electrical Enclosures

The accumulation of heat in an enclosure is potentially damaging to electrical and electronic devices. Overheating can shorten the life expectancy of costly electrical components or lead to catastrophic failure. It is therefore important that system designers are aware of the temperature implications of their designs prior to implementation.   Enclosure...

What is IP69K?

What is IP69K?   The IP69K rating is for applications where high pressure and high temperature washdown is used to sanitize equipment. The IP69K test specification was initially developed for road vehicles, especially those that need regular intensive cleaning (dump trucks, cement mixers, etc), but has been widely adopted in the Food & Beverage industries...
