This third edition cancels and replaces the second edition (ISO 10675-1:2016) which has beentechnically revised.
The main changes pared to the previous edition are as follows:
- new Table 1 added with abbreviations; old Table 1 has been split into Table 2 and Table 3:-in Table 4 (former Table 2) acceptance levels for maximum permissible pore sizes of porosity clustered porosity linear porosity and for lack of fusion have been added;- the acceptance levels in Clause 6 have been extended (General and tables);:- the captures of Figure B.1 to B.9 have been revised to conform with ISO 5817:2014;Figures C.1 and C.2 and the text have been revised to conform with ISO 5817:2014;- the document has been editorially revised.
