ASTM E257 Standard Test Method for Sulfur in Organic Compounds by Sodium Peroxide Bomb Ignition
ASTM E257用过氧化钠弹燃烧法测定有机化合物中硫含量标准试验方法
1. Scope
1.1 This test method covers the determination of sulfur in organic compounds by sodium peroxide bomb ignition. It is intended for application to samples of organic materials containing more than 0.5% sulfur. The presence of iron may require a separation such as is described.
1.2 This standard does not purport to address all of the safety problems, 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 . For specific hazard statements, see Section 7 and Notes 2 and 3.
Note 1-A test method based on an oxygen bomb combustion of petroleum products is described in Test Method D129.

ASTM E2573 Standard Practice for Specimen Preparation and Mounting of Site-Fabricated Stretch Systems to Assess Surface Burning Characteristics
ASTM E2573
Site-fabricated stretch systems used as interior finish are evaluated with Test Method E 84 to comply with building, fire, or life safety code requirements. This practice describes specimen preparation and mounting procedures for such materials and systems.
The limitations for this procedure are those associated with Test Method E 84.
Additional Limitations—This practice does not apply to test systems that cannot be used to produce self-supporting specimens. If the test specimen is not self-supporting, further guidance can be found in the appendix of Test Method E 84.
1. Scope
1.1 This practice describes procedures for specimen preparation and mounting when testing a site-fabricated stretch system to assess flame spread and smoke developed as surface-burning characteristics using Test Method E 84.
1.2 Testing is conducted with Test Method E 84.
1.3 This practice does not provide pass/fail criteria that can be used as a regulatory tool.
1.4 Use the values stated in inch-pound units as the standard, in referee decisions. The values in the SI system of units are given in parentheses, for information only; see IEEE/ASTM SI-10 for further details.
1.5 This fire standard cannot be used to provide quantitative measures.
1.6 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. Fire testing involves hazardous materials, operations, and equipment. This standard gives instructions on specimen preparation and mounting, but the fire-test-response method is given in Test Method E 84. See also Section 10.
1.7 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.
1.8 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes shall not be considered requirements of the standard.
