7.3 Test pieces machined from samples cut from a casting If applicable, the manufacturer and the purchaser shall agree on:  the location(s) on a casting where the sample(s) shall be taken;  the mechanical properties that shall be measured;  the minimum values, or allowable range of values, for these mechanical properties (for information, see Annex D). SIST EN 16079:2012

8.2.2 Frequency and number of tests Samples representative of the material shall be produced at a frequency in accordance with the process quality assurance procedures adopted by the manufacturer or as agreed with the purchaser. In the absence of a process quality assurance procedure or any other agreement between the manufacturer and the purchaser, a minimum of one cast sample shall be produced to confirm the material grade, at a frequency to be agreed between the manufacturer and the purchaser.
8.2.3 Separately cast samples The samples shall be cast separately in sand moulds and under representative manufacturing conditions. The moulds used to cast the separately cast samples shall have comparable thermal behaviour to the moulding material used to cast the castings. The samples shall meet the requirements of either Figures 1, 2 or 3. The samples shall be removed from the mould at a temperature similar to that of the castings. 8.2.4 Side-by-side cast samples Side-by-side cast samples are representative of the castings concurrently cast and also of all other castings of a similar relevant wall thickness from the same test unit. When mechanical properties are required for a series of castings belonging to the same test unit, the side-by-side cast sample(s) shall be produced in the last mould(s) poured. SIST EN 16079:2012
