— ISO 26262-2:2018,
— ISO 26262-3:2018,

4 General
4.1 Overview
The objective of this clause is to give an overview of the comparison in this document. This clause describes the contents of ISO 26262-12:2018 and the superseded clauses from ISO 26262-2:2018,ISO 26262-3:2018 and ISO 26262-4:2018. However, identical clauses (Clause 1 to Clause 4) in all parts are excluded from comparison. Additionally, annexes are also excluded from the comparison because of their informative nature.
123 differences are identified as the target of categorization by comparison. The overview for each clause is as follows.
— In Clause 5 regarding safety culture, 5 differences are categorized. These are mainly relevant to communication channels and changed because these are implemented to limited models of motorcycle.
— In Clause 6 regarding confirmation measures, 16 differences are categorized. These are mainly relevant to the level of independence required for confirmation reviews of work products and the definition of their level, and these are changed to adapt the scale of motorcycle development. ISO 26262-12:2018, Figure 3 is added for better understanding of independence.
— In Clause 7 regarding hazard analysis and risk assessment, 72 differences are categorized. These are mainly relevant to how the dynamic behaviour of motorcycle differed from other vehicles, and these are adapted by the classification of parameters for hazardous event (severity, exposure and controllability) and the introduction of MSIL.
—In Clause 8 regarding vehicle integration and testing, 20 differences are categorized. And in Clause 9 regarding safety validation, 10 differences are categorized. These are mainly relevant to the test feasibility for motorcycle and there is no assignment for ASIL D due to ASIL-MSIL mapping.
Figure 1 is reprinted from ISO 26262-12:2018 and it shows the relation of ISO 26262-12:2018 and the other parts of ISO 26262 series.
For detailed explanation of Figure 1, Table 1 shows the list of clauses/subclauses of ISO 26262-12:2018 and the superseded clauses/subclauses of the other parts of the ISO 26262 series, and remarks for them.
4.2 Categorization of differences
Table 2 explains the method of categorization of differences between ISO 26262-12:2018 and other parts of ISO 26262:2018 series.
The following differences are excluded from comparison and categorization results because they have no impact on the section meaning:
— reference number;
— existence of symbol, e.g. comma, hyphen, quotation mark;
— word form, e.g. singular/plural, verb form;
— article and preposition.
4.3 Interpretation of comparison tables
The comparison and categorization results are listed in tables. Different parts of sections are underlined except in case of figure or table constitution or no comparison target. Each superscript for individualization is shown with parentheses because of the possibility of confusing them with the original superscripts of compared sections as follows:
— superscript for footnote: marked by a letter and noted at the bottom of table, e.g. a, b, c;
— superscript for category: marked by number and noted in rightmost column, e.g. (1), (2), (3).
The notation “N/A” in first column and second column means that there is no section to be compared.
5 Comparison of safety culture
This clause explains the differences in content relating to safety culture between ISO 26262-12:2018 and ISO 26262-2:2018. The differences and their categorization are listed in Table 3.ISO TR 3152 pdf download.ISO TR 3152 pdf download
