ASTM E69 Combustible Properties of Treated Wood by the Fire-Tube Apparatus
ASTM E69 applies to fire-tube testing for combustible qualities of wood that have been treated to lessen flammability. This test method is concerned with the qualities of treated wood rather than the performance of a fabrication utilized as a construction part.
Scope:
The goal of ASTM E69 is to determine the combustibility of fire-retardant-treated wood specimens based on their weight loss % during controlled fire exposure settings. Other possible data include weight loss rate, blazing and after glowing time, temperature increase, and maximum vertical flame progress. This test method has proven valuable in comparing the effectiveness of fire-retardant chemicals and treatment formulations for wood and wood products in terms of fire performance.
Procedure
After conditioning, there are two main procedures for ASTM E69. Procedure A is used to determine the percentage loss of weight of specimens following flame exposure. The test is carried out in a laboratory hood or a room with no severe drafts. The burner is put within the empty fire tube, and the burner and gas regulator is set to produce a blue flame with a tall unclear inner cone that is roughly 11 in. (279 mm) in height. After this, the fire-tube weighing apparatus is adjusted, and the percentage loss of weight sustained by the test specimen is recorded at 30 second intervals. Only the final percentage loss of weight of specimens exposed to the flame is reported using procedure B. It’s a condensed version of procedure A.

Specimen size:
At the top of the fire tube, the flame is adjusted to create a temperature of 356 6 9°F (180 6 5°C).
Data
The following data is calculated in ASTM E69:
% Weight loss = (Wi 2 Wf)/ Wi/3 ×100
where:
Wi = initial weight, lb(g), and
Wf = final weight, lb(g).
Conclusion:
The goal of ASTM E69 is to determine the combustibility of fire-retardant-treated wood specimens based on their weight loss % during controlled fire exposure settings.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
