The test section of the tension test specimen shall be cast to size astj accordance with the dimensions shown in Fig. Responsibility for Quality Assurance 5. Unless aztm specified, only aluminum or producers foundry scrap shall be used in the re-melting furnace from which molten metal is taken for pouring directly into castings.

Foundry control shall consist of examination of castings by radiographic or other approved methods for determining zstm discontinuities until the gating, pouring, and other foundry practices have been established to produce castings meeting the quality standards furnished by the purchaser or agreed upon by the purchaser and the producer.

MoldRANGE provides an unbiased, databased, broader perspective of what is typically in the outdoor air. All tests are performed in accordance with the appropriate ASTM test methods.

Rejection and Rehearing Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Pure materials, recycled materials, and master alloys may be used to make alloys conforming to this specification. T1 Cooled from an elevated temperature shaping process ast naturally aged to a substantially stable condition.


It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The equivalent unified numbering system alloy designations are in accordance with Practice E The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

With plain cylindical ends, 4 in. T7 Solution heat-treated and stabilized. The following applies to all speci? Overall length, 4 in. Months after Hurricanes Irma and Maria caused massive destruction to infrastructure and buildings across Puerto Rico, life for many area residents is still filled with challenges.

If no locations are designated, one or more specimens shall be taken to include locations having signi? Ratings, in the case of heat-treatable alloys, based on T6 temper. Current edition approved May 10, Inthe Institute of Medicine IOM found that there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough and wheeze in otherwise healthy people; with asthma symptoms in people with asthma; and with hypersensitivity pneumonitis HP in individuals susceptible to that immune-mediated condition.


Last previous edition B — Limitations on the extent and frequency of such repairs, and methods of inspection of repaired areas should also be agreed upon. The conditions of arti? Unalloyed aluminum contains a minimum of N Refers to suitability of alloy to withstanding brazing temperatures without excessive distortion or melting. The tension test specimens shall be the standard 0.

Ability of alloy to withstand stresses from contraction while cooling through hot-short or brittle temperature range. T4 Solution heat-treated and naturally aged to a substantially stable condition. Conformance shall be determined by the producer by analyzing samples at the time the castings are poured, or samples taken from castings or tension test specimens representative of the castings.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. The type of packaging and gross weight of individual containers shall be left to the discretion of the producer unless otherwise agreed upon.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Peening may be accomplished either hot or cold and shall be performed by methods which are acceptable to the purchaser.

A major concern encountered by many residents in their daily lives is exposure to the presence of high concentrations of mold. A number in parentheses indicates the year of last reapproval. F Other Elements—Total shall be the sum of unspeci? E S1 units for information only.
