This practice is intended to assist the various technical committees in the use of uniform methods of indicating the number of digits which. Excel: Round towards Even Per ASTM-E29 If you like this topic, please consider downloading the entire e-book. The guidance published by the ASTM in their rule E29 says that numbers ending in should round towards the even number.

Baranwal 9. Veith For example, the automotive manufacturers are beginning to design vehicles to last miles with minimum maintenance. This severely challenges m a n y rubber part manufacturers, perhaps more than other groups in the automotive supply base, to improve their quality and reduce variation.
One large source of product variation in the rubber industry can be nonuniformity of received raw rubber and other compounding ingredients. There are currently over ASTM Standard Methods that are actively used to test these raw materials used in the rubber industry. The mixing process also is a very large source of variation in the factory.
There are another 25 ASTM methods that are used to test the quality of mixed batches. This book is designed to be a practical guide to the rubber technologist in selecting the appropriate methods for use in a testing program of raw materials, compounding ingredients, or mixed stock.
This book characterizes each group of raw materials. The wording in 5.
This is becoming more common, as more and more third party inspectors who have little specific knowledge are reviewing the test results. A standard states a hardness range of, say, HRC. The hardness test report states Is this acceptable or does it represent an out-of-tolerance condition? How about if the other testing is acceptable tensile, impact, etc Obviously, if the other tests are not acceptable, the hardness value is irrelevant.
The controlling document is the material standard. If it required However, if it states the requirement as , then it should be acceptable to round per E29 prior to determining acceptance, which is what it sounds like your client is asking.This is true for other physical properties, like tensile requirements.
However, if it states the requirement as , then it should be acceptable to round per E29 prior to determining acceptance, which is what it sounds like your client is asking.
There are currently over ASTM Standard Methods that are actively used to test these raw materials used in the rubber industry. About this book Introduction This book examines statistical techniques that are critically important to Chemistry, Manufacturing, and Control CMC activities. That would still be acceptable because the precision of the hardness specification dictates the precision used in E29 rounding.
NOTE: This manual does not purport to address all of the safety concerns, if any, associated with its use. Obviously, if the other tests are not acceptable, the hardness value is irrelevant.
