ASTM E119-12a Fire Tests of Building Construction and Materials
ASTM E119-12a test method exposes a specimen to a standard fire controlled to achieve specified temperatures throughout a specified time period. The test provides a relative measure of the fire-test-response of comparable assemblies under these fire exposure conditions.
ASTM E119-12atest methods described in this fire-test-response standard are applicable to assemblies of masonry units and composite assemblies of structural materials for buildings, including bearing and other walls and partitions, columns, girders, beams, slabs, and composite slab and beam assemblies for floors and roofs. They are also applicable to other assemblies and structural units that constitute permanent integral parts of a finished building.
A sample of the test material or a pre-constructed portion of it, as in the case of walls, partitions, flooring, ceilings, and roofing, is placed in the test furnace. The orientation of the materials, either a vertical furnace is used in the case of walls, columns, and partitions, or a horizontal furnace is used in the case of floors, ceilings, and roofs. Under a timed evaluation, a mixture of gas and air is ignited and fed into the furnace assembly. For typical one or two-hour rating tests, the internal temperature of the furnace must rise according to pre-set temperatures. Standard temperature levels are 1300 degrees Fahrenheit after five minutes, 1400 °F after 15 minutes and a minimum of 1550 °F after 30 minutes, and so on. After the test, materials are checked for their structural integrity, especially in the case of load-bearing assemblies.

The length of the column exposed to fire shall be not less than 9 ft. (2.7 m)
The area exposed to fire is not less than 100 ft. (9 m2), with neither dimension less than 9 ft. (2.7 m).
ASTM E119-12a test method is important to specify the burning characteristics of building materials. The durability and reliability of the material is tested and recommendations for its improvement are provided.
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 is a standard test method for the analysis of sulfochromate etches solution 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.
