A distribution is presumed to be multimodal if it results from the marked effect of at least one cause inducing a significant difference between the produced items.<\/p>\n<p>This part of ISO 22514 applies, for example, to characteristics generated by processes such as the following:<\/p>\n<ul>\n<li>\n<p>multi-cavity casting: simultaneously producing several identical parts from a mould featuring several cavities.<\/p>\n<p>Since each cavity has its own geometry and its own position in the mould architecture, it can create a systemic difference on the output result;<\/p>\n<\/li>\n<li>\n<p>multi-fixture machining: a part produced at the same time, but the produced parts are positioned in relation to the production tool by different fixture systems.<\/p>\n<p>Since each fixture has its own geometry, mount clamps, etc., it can create a systematic difference on the output result;<\/p>\n<\/li>\n<li>\n<p>batch load treatments: heat treatment applied at the same time on a set of identical parts (the batch load), distributed within a pre-defined space of furnace. The position of an item of the batch relative to the furnace can influence the output result.<\/p>\n<\/li>\n<\/ul>\n<p>Each cavity, fixture, or position in the batch load corresponds to a different state. The multi-state process can be understood as the result of the combination of different states within the same process (e.g. cavity, fixture, position in the batch load).<\/p>\n<blockquote>\n<p>NOTE It needs to be ensured that such systematic differences, if any, constitute only a very small proportion of permissible error so that their impact is harmless and do not affect the capabilities of the process.<\/p>\n<\/blockquote>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>Foreword
