ASTM E1756-08 rus PDF

Full title and description

St ASTM E1756-08 rus — Standard Test Method for Determination of Total Solids in Biomass (ASTM E1756, edition 2008) presented here as a product/record entry; this item title indicates the 2008 ASTM E1756 test method and a Russian-language presentation or translation (rus) of that edition. The standard specifies procedures for determining the mass of total solids remaining after drying biomass samples and gives two basic test methods (drying oven and moisture analyzer) and related apparatus and sampling guidance.

Abstract

This standard describes laboratory procedures to determine total solids in biomass by drying samples and reporting results on a moisture-free basis. It covers suitable sample types (including samples prepared per related ASTM practices), recommended drying temperatures and times (Test Method A: convection oven at 105 ± 3 °C; Test Method B: infrared moisture analyzer), required apparatus (analytical balance, drying pans/desiccator, moisture analyzer), and notes on reporting and precision. The method is intended for biomass feedstocks, fermentation residues, and other similar materials where total solids (dry matter) is needed for analytical adjustment.

General information

• Status: Historically the E1756-08 edition (2008) has been maintained and reapproved in later years; the ASTM E1756 family remains active with more recent editions/reapprovals published after 2008.
• Publication date: Original designation E1756-08 published May 1, 2008 (E1756-08). Subsequent reapprovals/editions include reapprovals in 2015 and 2020 and a newer 2024 edition.
• Publisher: ASTM International (American Society for Testing and Materials).
• ICS / categories: 65.040.20 (Buildings and installations for processing and storage of agricultural produce / biomass processing categories and related industrial chemistry/energy categories).
• Edition / version: E1756-08 (2008) — referenced here as the 2008 edition; later reapprovals and a 2024 revision exist (ASTM E1756-24).
• Number of pages: Short method document — commonly published as a 3-page test method in the ASTM Annual Book of Standards (3 pages for E1756-08 in published extracts).

Scope

ASTM E1756-08 covers the determination of total solids remaining after drying a biomass sample and is applicable to materials prepared according to Practice E1757 or extractive-free materials per Test Method E1690. The procedure provides two primary approaches: Test Method A (drying in a convection oven at about 105 °C) and Test Method B (loss-on-drying using an infrared moisture analyzer). It excludes particulate wood fuels (for which Test Method E871 is recommended) and remarks that users must establish appropriate safety practices. The method is intended to enable reporting analytical results on a moisture-free (dry) basis.

Key topics and requirements

• Definition and purpose of “total solids” for biomass sample reporting.
• Two test procedures: Test Method A (oven drying at 105 ± 3 °C) and Test Method B (infrared moisture analyzer / loss-on-drying).
• Required apparatus: analytical balance (sensitivity to 0.1 mg), drying oven, desiccator, moisture analyzer, and suitable drying pans.
• Sampling and sample preparation references: Practice E1757 and Test Method E1690 for extractive-free preparation; use E871 for particulate wood fuels.
• Precision and reporting guidance, including statistical tables for critical differences and confidence limits (precision assessed in interlaboratory data).

Typical use and users

Laboratories and practitioners in biomass analysis, bioenergy and biofuel production, environmental testing, agricultural residue characterization, university research, and process control use this method to determine dry matter (total solids) for mass-balance calculations and to report other compositional analyses on a dry basis. It is used by contract testing labs, pilot plants, biomass conversion researchers, and industry quality-control personnel.

Related standards

Directly referenced and related ASTM standards include Practice E1757 (sample preparation for biomass), Test Method E1690 (preparation of extractive‑free material), Test Method E871 (moisture in particulate wood fuels), and other committee documents from ASTM Committee E48 (biotechnology/biomass conversion) that govern sampling and analytical procedures. Users should consult the latest ASTM E1756 edition and referenced practices for complete cross-references.

FAQ

Q: What is this standard?

A: ASTM E1756-08 is the 2008 edition of the ASTM test method titled “Standard Test Method for Determination of Total Solids in Biomass,” which prescribes procedures to measure the mass of total solids in biomass samples after drying.

Q: What does it cover?

A: It details two methods for determining total solids (oven-drying at about 105 °C and loss-on-drying with an infrared moisture analyzer), lists required apparatus and sampling references, and provides guidance on reporting results on a moisture-free basis. The method points users to related ASTM practices for sample preparation and notes exclusions (e.g., particulate wood fuels addressed by E871).

Q: Who typically uses it?

A: Analytical laboratories, biomass/bioenergy researchers, process engineers, quality-control personnel in biomass processing and conversion industries, and academic researchers conducting compositional or moisture-corrected analyses.

Q: Is it current or superseded?

A: The E1756-08 edition is the 2008 baseline edition that was later reapproved and maintained; the ASTM E1756 family has later reapprovals (2015, 2020) and a subsequent revision designated E1756-24 (2024). Users who require the current normative requirements should refer to the latest ASTM E1756 edition (check ASTM for the most recent text).

Q: Is it part of a series?

A: Yes — E1756 is part of a set of ASTM methods and practices addressing biomass sampling and analysis; it references and is used with Practice E1757 (sample preparation), Test Method E1690 (extractive-free preparation), Test Method E871 (wood fuels), and other E48 committee documents. The E1756 designation is maintained across reapprovals and revisions as part of the ASTM portfolio for biomass test methods.

Q: What are the key keywords?

A: Biomass, total solids, dry matter, moisture, oven drying, loss-on-drying, moisture analyzer, ASTM E1756.
