Letter regarding soliciting opinions on Hunan Province's local measurement technical specifications "Specifications for Calibration of Test Molds for Aggregate Crushing Indexes" (Draft for Comments)
Release time：2024-08-21click：2
The aggregate crushing value is usually used to measure the ability of stone to resist crushing under gradually increasing loads. It is an important indicator to measure the mechanical properties of stone to evaluate its applicability in construction projects. It is used as an aggregate crushing index test. The crushing value test mold used is widely used in engineering construction fields such as water conservancy, electric power, urban construction, highways, railways, and mines.
With the improvement of safety awareness in construction projects, aggregate crushing value test molds have also been widely used in the construction process. The quality of the aggregate crush value test mold and whether its measurement performance is accurate, reliable and stable play a vital role in the quality of the project.
The geometric dimensions of the aggregate crushing index test mold have a significant impact on the test results of the aggregate crushing index, which directly affects the evaluation of its applicability in highway and other projects, and also has a negative impact on the construction unit. And the supervision unit has a direct guiding role in the control of aggregate raw materials.
Based on the needs of my country’s construction projects, it is necessary to unify and standardize the calibration method of the aggregate crushing value test mold. In order to ensure the accuracy and reliability of the traceability of the aggregate crushing value test, It is particularly important to formulate a unified, standardized and operable measurement technical specification, which can ensure the quality of project construction.
According to the requirements of the "Notice of the Hunan Provincial Market Supervision and Administration Bureau on Issuing the 2023 Hunan Provincial Local Measurement Technical Standards Project Plan" (Xiang City Supervision and Measurement Letter [2023] No. 27), by The Hunan Provincial Local Metrology Technical Specification, which was organized and formulated by the Hunan Provincial Institute of Metrology and Inspection, has completed the draft of the "Aggregate Crushing Index Mold Calibration Standards" and is now open to the public for comments.
We welcome your valuable comments and fill out the "Feedback Form for Solicitation of Comments". Please provide feedback to the Hunan Provincial Institute of Metrology and Inspection before October 19, 2023. Thank you for your participation and support.
