BABT would love to commission testing of your power supply. I suggest that you respectfully tell them where to get off.
The 701 form has three options for you to choose from. 1. You do not have a test report and intend to test the product at a BABT recognised lab. 2. You are in possesion of a test report and you wish BABT to 'approve' it. 3. You are in possesion of a test report and you wish to self declare to the Low Voltage Directive. I suggest you choose option 3 as most companies do nowadays. In your specific case you need only complete the 701 form if you have not completed one before. When changing the power supply you only have to obtain and keep one file a test report. BABT should not be interested assuming you have taken option 3 above. However there are those in BABT who would disagree. It really depends on who you talk to. Best regards Barry Singleton Approvals Specialist ------------- Original Text From: [email protected] (Roger Prenger), on 11/10/96 11:33: Treggers, I am considering changing the power supply on a telecom terminal we market to the UK. I ask BABT what was required of us to maintain our current approval for the terminal except with a new power supply. They replied that we must fill out a "BABT 701 safety form and, if appropriate, they (we) must commission type tests in respect of switch mode spectral noise output at a UK test laboratory to verify that the new psu complies with the PSTN network access requirements." I intend to call BABT to clarify that statement, but since the day has come and gone in UK, I thought perhaps someone on the network here could give me some information I can use before the week ends. 1) The BABT 701 specifies the basis of safety evaluation should be to EN 60950 PLUS EN 41003. Is EN 41003 not included in EN 60950 or is EN 41003 a seperate entity? I thought I heard at one point the EN 41003 was represented in Clause 6 of the EN 60950. 2) What tests are required for testing the "...switch mode spectral noise..." and is this covered in either the 60950 or the 41003? 3) Anyone want to expound upon a method to determine if indeed the test falls into the "...if appropriate, ..." category?
