请问ASTM D2974 耐冲击试验的方法和标准是什么?我买了设备却无法按客人要求进行验证产品
ASTM Designation: D 2974 – 00
Standard Test Methods for Moisture, Ash, and Organic Matter of Peat and Other Organic Soils1
This standard is issued under the fixed designation D 2974; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 These test methods cover the measurement of moisture content, ash content, and organic matter in peats and other organic soils, such as organic clays, silts, and mucks.
1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
2. Referenced Documents
2.1 ASTM Standards:
D 653 Terminology Relating to Rock, Soil, and Contained Fluids2
D 3740 Practice for the Evaluation of Agencies Engaged in the Testing and/or Inspection of Soil and Rock as Used in Engineering Design and Construction2
D 4753 Standard Specifications for Evaluating, Selecting, and Specifying Balances and Scales for Use in Soil and Rock Testing2
E 145 Specification for Gravity Convection and Forced Ventilation Ovens3
3. Terminology
3.1 Definitions:
3.1.1 For common definitions of terms in this standard, refer to Terminology D 653.
4. Summary of Test Methods
4.1 Test Method A—Moisture is determined by drying a peat or organic soil sample at 105°C. The moisture content is expressed either as a percent of the oven dry mass or of the as-received mass.
4.2 Test Method B—This is an alternative moisture method which removes the total moisture in two steps: ( 1) evaporation of moisture in air at room temperature (air-drying), and (2) the subsequent oven drying of the air-dried sample at 105°C. This method provides a more stable sample, the air-dried sample, when tests for nitrogen, pH, cation exchange, and the like are to be made.
4.3 Test Methods C and D—Ash content of a peat or organic soil sample is determined by igniting the oven-dried sample from the moisture content determination in a muffle furnace at 440°C (Method C) or 750°C (Method D). The substance remaining after ignition is the ash. The ash content is expressed as a percentage of the mass of the oven-dried sample.
4.4 Organic matter is determined by subtracting percent ash content from one hundred.
