The supplier shall be responsible for the performances of all inspection and tests required by the relevant International Standard, specification or customer requests, prior to shipment of the product.
If the purchaser wishes to inspect the product at the supplier’s works, he or she shall notify the supplier at the time of placing the order.
5.4 Chemical composition
The chemical composition of ISO-MgA14Zn, ISO-MgMn2(A), ISO-MgZn6Zr(A), ISO-MgGd9Y2Nd1Zr, ISOMgGd8Y2ZrAgEr and ISO-MgGd9Y4Zn1Zr shall conform to the requirements specified in Table 2. The chemical composition of other alloys shall conform to the requirements specified in ISO 3116:2019. If the purchaser requires content limits for elements not specified in ISO 3116:2019, these limits shall be stated in the order document.
The products shall be free from defects detrimental to their required use and performance.
While an operation designed to mask a fault is not permitted, the elimination of a superficial fault is
permissible, provided that the dimensional tolerances remain.
6 Test procedure
61 Sampling
6.1.1 Specimens for chemical analysis
The specimens for chemical analysis shall be cast from molten metal samples taken at the time of casting.
Their shape and conditions of production (mould design, cooling rate, mass, etc.) shall be so designed that their composition is homogeneous, and is suitable for the method of analysis which is agreed between the supplier and the purchaser.BS-ISO-23694-2021
