Asbestos should be covered by the Rotterdam Convention, says ETUC
The European Trade Union Confederation (ETUC) is concerned by the direction taken by the negotiations under way on the inclusion of chrysotile asbestos on the list of substances covered by the Rotterdam Convention. This week, the countries that signed the Convention met up in Rome to decide whether or not to add two pesticides and chrysotile asbestos to the list. ‘It’s unacceptable for chrysotile ...

Asbestos Disease Awareness Organization Outraged that Seven Countries Prevented the Inclusion of Chrysotile Asbestos in the UN Rotterdam Convention List of Hazardous Substances
The Asbestos Disease Awareness Organization (ADAO), which combines education, advocacy, and community as the leading U.S. organization serving as the voice of asbestos victims, is outraged after the 2013 United Nations Rotterdam Convention failed to reach consensus to add chrysotile asbestos to the Prior Informed Consent (PIC) list of hazardous substances. All six types of asbestos are ...

Preventing Exposure Risks to all Forms of Asbestos in Puerto Rico as EPA Releases Final Risk Evaluation for Chrysotile
This past December, the U.S. Environmental Protection Agency (EPA) released its Final Risk Evaluation for Asbestos, Part 1: Chrysotile Asbestos. The document addresses the agency’s determinations on which conditions of use may present unreasonable risks to the environment and human health, and was completed as part of the agency’s mission under the Toxic Substances Control Act (TSCA). ...

ASTM D2589 / D2589M - 88(2011)e1 Standard Test Method for McNett Wet Classification of Dual Asbestos Fiber
Normally, results obtained by this test method are reproducible under comparable laboratory conditions. However, it must not be expected that results obtained by different operators at various laboratories and times will be in exact agreement due to some seemingly minor procedural change. Moreover, results for longer fiber grades are influenced to a greater extent by differences ...
-
ASTM D2947 / D2947M - 88(2011)e1 Standard Test Method for Screen Analysis of Asbestos Fibers
Test results give some indication of the apparent fiber length distribution in the sample tested. Sieves are ideally suited to measure particle size and particle size distribution when all three axes of the particle are equidimensional or the particle is of spherical shape. Asbestos fibers differ considerably from these ideal conditions and, therefore, results depart ...

Pesticide tributyltin added to trade “watch list” - FAO
Over 120 countries party to the Rotterdam Convention agreed to add the pesticide tributyltin to a global trade 'watch list', but were unable to reach consensus on the inclusion of chrysotile asbestos and the pesticide endosulfan during negotiations here last week. The conference reaffirmed that governments have an obligation to use the Convention's information-sharing mechanism to inform others ...

ASTM D2752 / D2752M - 88(2011)e1 Standard Test Methods for Air Permeability of Asbestos Fibers
The degree of fiberization or subdivision of the asbestos fiber bundles in a specimen is related to its resistance to air flow. The number and size of the pores in the specimen are a function of the size of the fiber bundles and determine the resistance to air flow through the plug. Test specimens that have undergone a higher degree of fiberization will yield higher ...

ASTM D2985 / D2985M - 92(2011)e1 Standard Test Method for Color of Asbestos
The color of asbestos is of commercial significance when it is to be incorporated into products, the color of which is affected by the color of the asbestos, and for which color specifications must be met. Whiteness is required of asbestos for use in white or pale-colored products. Yellowness is significant in asbestos for use in pastel-colored products where ...

ASTM D2590 / D2590M - 98(2011)e1 Standard Test Method for Sampling Chrysotile Asbestos
Sampling and conditioning are equally as important as testing. The reliability of the test results depends primarily upon how well the specimens tested represent the true character and condition of the lot of asbestos fiber. Much care and effort are required to be sure that all the sampling operations are systematic or at random and are representative. Failure to provide a ...

ASTM C1154 - 06(2011) Standard Terminology for Non-Asbestos Fiber-Reinforced Cement Products
1. Scope 1.1 This standard covers definitions pertaining to non-asbestos fiber-reinforced cement products under the jurisdiction of Committee C17. 2. Referenced Documents (purchase separately) ASTM Standards C150 Specification for Portland Cement C618 Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for Use in Concrete C966 Guide for Installing Asbestos-Cement ...

ASTM D3752 - 98(2011) Standard Test Method for Strength Imparted by Asbestos to a Cementitious Matrix
This procedure facilitates the comparison of different types or grades of asbestos based on their contribution to the flexural modulus of rupture; that is, the reinforcing value, which is considered the most pertinent property for the manufacture of asbestos-cement products. This test method is primarily intended for fiber grades used normally in ...
-
ASTM C458 / C458M - 98(2011)e1 Standard Test Method for Organic Fiber Content of Asbestos-Cement Products
This test method covers the determination of the organic fiber content of asbestos-cement products. Three apparatuses shall be used: sieve; drying oven; and an apparatus for determination of total carbon by direct combustion. Hydrochloric acid should be used as a reagent. A calculation shall be made to determine the organic fiber content. Repeatability of the mass of organic fiber ...
-
ASTM C1096 / C1096M - 07(2011)e1 Standard Test Method for Determination of Wood Fiber in Asbestos Cement
The determination of wood fiber in asbestos-cement products is necessary because such fibers may be added when multi-wall paper bags containing the asbestos are included in the batch formulations, or cellulose may be added as a processing aid during the manufacture of the products. Although moderate concentrations of wood fiber usually have a negligible effect on product ...

This test method covers the standard for testing of asbestos-cement pipe for hydrostatic strength, flexural strength, crushing strength, straightness, and uncombined calcium hydroxide. Hydrostatic pressure test is performed by placing the pipe with a factory-assembled joint, in a hydrostatic pressure testing machine. Air is expelled and an internal water pressure at a uniform rate ...

Chrysotile and Other Forms of Asbestos Still Pose Hazards in Puerto Rico
In Puerto Rico and across much of the Caribbean, chrysotile is one of the most frequently found forms of asbestos. Chrysotile is just one of six asbestos and asbestiform minerals that regulatory agencies, such as the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA), recognize. In addition to chrysotile, the others include actinolite, amosite, ...
