    Significance and Use

    4.1 The sampling procedures described are intended for use in the procurement of samples of hydraulic cement after it has been manufactured and is ready to be offered for sale. They are not intended as sampling procedures for quality control purposes during manufacturing. The testing procedures outlined cover the amount of testing to be done and provide guidance for reporting on conformance or non-conformance of cements with requirements of purchase specifications.

    4.2 This practice is referenced as the procedure for sampling natural cement (Specification C10/C10M), masonry cement (Specification C91/C91M), portland cement (Specification C150/C150M), blended hydraulic cement (Specification C595/C595M), expansive hydraulic cement (Specification C845/C845M), hydraulic cement based on a performance specification (Specification C1157/C1157M), plastic stucco cement (Specification C1328/C1328M), and mortar cement (Specification C1329/C1329M), and

    4.3 Most building codes and construction specifications require that hydraulic cement to be used in the work meet the applicable requirements of the relevant purchase specifications, such as Specifications C10/C10M, C91/C91M, C150/C150M, C595/C595M, C1157/C1157M, C1328/C1328M, C1329/C1329M, or C845/C845M. If the code or specification requires sampling of the manufactured cement, the provisions given in 4.4 are applicable. Not much cement is sold on the basis of such sampling and testing. A useful discussion of sampling and testing cement is contained in ACI 225.1R.

    4.4 The procedures covered in this practice should be done by or for purchasers of hydraulic cement who are using a code or specification that requires sampling and testing to determine if the samples conform to the relevant acceptance specifications. The testing is done using specified methods to determine whether the samples yield test results that conform to the specification, and the tests serve as a basis for acceptance or rejection of the lot of material sampled.

    4.5 It is neither intended nor required that all cements be tested using all the test methods referenced in Section 2.

    1. Область применения

    1.1 Данная методика описывает процедуры отбора проб и определения объема испытаний гидравлического цемента после того, как он изготовлен и готов для продажи.

    1.2 Значения, выраженные либо в единицах СИ, в, либо дюйм-фунтах, считаются стандартными по отдельности. Значения, выраженные в каждой из систем, не являются в точности эквивалентными, поэтому каждую систему необходимо использовать независимо от другой. Объединение значений из двух систем может привести к несоответствию стандарту. Значения в единицах СИ [или дюйм-фунтах] получаются при измерениях в единицах СИ [или дюйм- фунтах], либо при соответствующем пересчете, используя приведенные в Стандарте IEEE/ASTM SI 10 Правила преобразования и округления результатов измерений, произведенных в других единицах. Значения указаны только в единицах СИ, если дюйм-фунты не используются в данной методике.

    1.3 В тексте стандарта имеются примечания и сноски, в которых указан пояснительный материал. Эти примечания и сноски (за исключением тех, что в таблицах и на рисунках) не должны рассматриваться как требования стандарта.

    1.4Данный стандарт не претендует на полноту описания всех мер безопасности, если таковые имеются, связанных с его использованием. Вся ответственность за установление соответствующих правил техники безопасности и мер по охране здоровья, а также определение пределов применимости регламентов до начала использования данного стандарта, лежит на пользователе стандарта.
