The test report behind a Certificate of Compliance, in the order you do it, with the value each test has to make and the clause that sets it. The sheet is only half the job; the other half is the installation being right before you start.
Clause numbers are from SANS 10142-1 Ed 3.3 (public-enquiry draft). The licensed Ed 3.3 book is the authority, and the ECB's test report template is the form most SA sparkies hand in.
Tested with a supply of 4–24 V and 0,2 A or more. Every extraneous conductive part that has to be bonded, checked back to the earth bar. 8.6.2.
DB earth terminal to the earthing terminal of every point of consumption and switch. Sockets tested with a plug inserted so the earth pin counts. 6 A allows 1,533 Ω, 63 A allows 0,146 Ω. Full table here. 8.6.3.
Both ends of each live conductor removed, separated, tested for continuity, then reconnected to the same terminal. A ring that "works" can still be two radials. 8.6.4.
Measured at the main switch. The fault current must reach at least 3× the rated current of the device up to 63 A, and above 63 A the disconnection time must not exceed 5 s. Record the reading. 8.6.5.
Main switch off, measure the supply neutral against an earth external to the installation (a spike driven into wet ground is allowed as the reference). 0 to 25 V: notify the user or lessor. Above 25 V: notify the supplier and the user. Above 50 V: disconnect the installation and notify the supplier. 8.6.6.
Older testing guides (ECB, Edition 3) list only the 25 V and 50 V steps. Edition 3.3 (Amdt 3) adds the 0–25 V line.
8.6.7 sets no ohm value of its own: earth resistance is determined to SANS 10199, or with an appropriate instrument. Where the supplier provides an earthing terminal (TN) the test is optional (8.6.7.2). Where there is no earthing terminal or an alternative supply is installed, it is how you confirm the earthing system. Electrode calculator here.
Test voltage at least twice nominal, minimum 500 V, with dimmers, EL units, SPDs and other electronics disconnected. Sub-boards may be split, but each section still has to make 1,0 MΩ. Details here. 8.6.8.
All load off, then maximum available load on, measured at the point of control. Outside the standard voltage limits (5.4.2) the supplier gets notified. 8.6.9, 8.6.10.
Measured at the outlets, on each phase conductor of the outlet, and the tripping current recorded on the report. Every unit in the DB gets its own test. Then the test button, to prove the mechanism (8.6.12 is a function check, not a sensitivity test). 8.6.11.
Annexure 1 of SANS 10142-1 is the test report layout; the ECB publishes its own template around the same tests. A CoC built on a test report nobody can read is a dispute waiting for a sale to fall through.
The testing is the clean half of a CoC job. The other half is paperwork: readings written down as you go, a report that survives a bank or a buyer looking at it, an invoice that gets paid. That is the part that eats your evening and the part that gets you called back.
Annexure 1 layout, every reading flagged against its value as you type, EL tripping current per unit, then a readable PDF you can forward to the wireman, the bank or the buyer. Invoices, quotes and job cards in the same file, offline.
