D6453-99 – Standard Test Method Technical Guide
📜 Standard Scope and Referenced Documents
The standard, issued under the fixed designation D 6453 – 99, provides a comprehensive guide for the electronic exchange of mechanical test data for soils and rocks. It covers recommended data formats to ensure that a standardized file prepared by one party can be read by any other party adhering to this guide. It is important to note that this guide does not cover digital geospatial data, which is specifically treated under Specification D 5714.
The guide relies on several key external standards for definitions, date formatting, and data transfer structures. The following table highlights the primary supporting standards referenced.
| 🟦 Standard ID | 📐 Title | 🎯 Application in D6453 |
|---|---|---|
| D 653 | Terminology Relating to Soil, Rock, and Contained Fluids | Source for core geological and geotechnical definitions |
| D 5714 | Specification for Content of Digital Geospatial Metadata | Defines the scope of excluded geospatial data |
| E 1013 | Terminology Relating to Computerized Systems | Defines digital and system-specific terminology |
| ANSI X3.30 | Representation for Calendar Date and Ordinal Date | Specifies the format for date data elements |
🧩 Terminology and Data Group Definitions
Precise language is critical for data exchange. General technical definitions within this guide follow Terminology D 653, while computer-related terms follow Terminology E 1013. The guide also establishes three specific operational definitions for structuring data files.
| 📏 Term | ⚡ Specific Definition (D6453-99) |
|---|---|
| Data Element | A logically basic item of data. |
| Data Group | A collection of data elements which are related. |
| Group | A collection of related information about a test. |
📊 Principal Data Elements: The guide defines the principal data elements considered important for permanent storage. These are not intended as rigid requirements for any single database. The standard format permits users to include only the elements they require for a specific exchange, providing critical flexibility.
⚙️ Significance of Standardized Data Exchange
Computers are integral to modern testing laboratories, yet the variety of automated test devices and software programs has resulted in a critical lack of consistency in storage formats. This makes exchanging computerized test data files between organizations time-consuming and expensive. D6453-99 addresses this problem by presenting a standard yet versatile format designed to facilitate the exchange of data between computer programs, users, and agencies.
This guide offers an organized collection of information and does not recommend a specific course of action. It cannot replace education or experience and must be used in conjunction with professional judgment. The “Standard” designation means the document has been approved through the ASTM consensus process.
⚠️ Safety and Regulatory Note: This standard does not purport to address all safety concerns associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
💡 Internal Storage Flexibility: It is not necessary to store your internal test data in this guide’s format. A program adhering to the guide must only have the capability to read or write test data in this exchange format, allowing laboratories to maintain existing internal database structures.
❓ Frequently Asked Questions
🔍 What specific type of data does this guide aim to standardize?
This guide specifically covers the recommended data formats for the exchange of mechanical test data for soils and rocks. Digital geospatial data is explicitly excluded and is covered by Specification D 5714.
💡 Does my laboratory have to change its internal data storage to comply?
No. It is only mandatory that a program adhering to this guide has the capability to read or write test data in this format for exchange purposes. Internal storage practices remain flexible.
⚡ What is the difference between a ‘Data Group’ and a ‘Group’ as defined here?
A Data Group is a specific collection of related data elements. A Group is a broader collection of related information that pertains to an entire test.
📌 How does the guide define the role of the user in applying this standard?
The standard offers a series of options and does not recommend a specific course of action. It is not intended to represent the standard of care and must be applied with professional judgment, considering a project’s many unique aspects.
