Standard Practice for Calculating Sample Size to Estimate, With a Specified Tolerable Error, the Average for Characteristic of a Lot or Process<\/p>\n","protected":false},"excerpt":{"rendered":"
This standard covers simple methods for calculating the number or quantity of samples to be taken in a random sample of a certain strictly defined order to determine a quality measure for all of the product units contained in a batch of material or produced as a result of a process. Using the method given in this standard, the average value of a characteristic or the proportion of unsuitable manufactured units produced during a manufacturing process can be easily determined. If the manufacturing process is not in a state of statistical control, the result obtained from the calculations will not provide forecasts for future production. The implementation of the method is applicable only if the samples are a source of variability, not to the extent of sources of variability.
\nThis standard does not intend to provide information on how to handle materials or products or how to determine appropriate sampling units with a certain reliability. It is the main goal to determine how many samples are to be taken after defining<\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":""},"product_brand":[],"product_cat":[175],"product_tag":[],"class_list":["post-166784","product","type-product","status-publish","product_cat-tse","first","instock","purchasable","product-type-simple","entry","content-bg","loop-entry"],"taxonomy_info":{"product_cat":[{"value":175,"label":"TSE"}]},"featured_image_src_large":false,"author_info":[],"comment_info":"","_links":{"self":[{"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product\/166784","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/media?parent=166784"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product_brand?post=166784"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product_cat?post=166784"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/onlinestandart.com\/en\/wp-json\/wp\/v2\/product_tag?post=166784"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
