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...

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...
