In the event of a conflict between the text of this specification and the references cited herein (except for associated detail specifications, specification sheets or MS standards
21、), the text of this specification shall take precedence. Nothin in this specification, however, shall supersede applicable laws and regulations un f ess a specific exemption has been obtained. 3. REQUIREMENTS 3.1 Qualification. The abrasive materials furnished under this specification shall be produ
22、cts which are authorized by the qualifying activity for listing on the applicable qualified products list at the time set for opening of bids (see 4.3 and 6.4). 3.2 Material. The abrasive material shall be manufactured as required to produce a product which is uniform, homogeneous, noncaking, and fr
23、ee flowing, in full conformance with the requirements of this specification. Also, the abrasive material which contains specific agents such as organic matter, asbestos, and wollastonite and pectolite minerals, and actinolite and tremolite minerals, water soluble and toxic substances (except as allo
24、wed by this specification), or other extraneous materials and entirely suitable for the purpose intended shall be appropriately documented.

Where the agent is present in the media, as a result of being an impurity or as a trace constituent of other materials, levels of this agent shall be maintained as low as feasible and under no circumstances shall levels of the agent in the media
26、 exceed 0.001 percent by weight of the material. The abrasive may be any material meeting the requirements of this specification. 3.3 Recovered materials. Unless otherwise specified herein, all equipment, material, and articles incorporated in the products covered by this specification shall be new
27、and may be fabricated using materials produced from recovered materials to the maximum extent practicable without jeopardizing the intended use. The term “recovered materials“ means materials which have been collected or recovered from solid waste and reprocessed to become a source of raw materials,
28、 as opposed to virgin raw materials. None of the above shall be interpreted to mean that the use of used or rebuilt products is allowed under this specification unless otherwise specifically specified. 3.4 Quantitative reauirements.

The moisture content of abrasive material delivered in bags or sacks shall be less than 0.5 percent by weight as specified (see 4.5.5). 3.4.3.2 Delivery
32、 in bulk. When dry material is specified (see 6.2), the moisture content of the abrasive shall be less than 0.5 percent by weight. There is no moisture limitation on bulk abrasives not specified as dry material. The abrasive is purchased by weight, therefore the moisture content of the wet material
33、shall be determined as specified in 4.5.5 and a correction factor derived from the formula as specified in 3.4.3.3 shall be applied to the gross weight of the wet material. 3.4.3.3 Correction of gross weight of bulk shiments for moisture content. When abrasives are acquired by net weight in bulk (se
34、e 6.2), the moisture content of the material shall be accurately determined at the time of weighing and the new weight calculated by subtracting the amount of moisture present from the gross weight, as follows: New weight = Gross weight X (1 - percent moisture/100) 3.4.4 Weight channe on ignition. T
35、he abrasive weight change as a result of ignition shall be within the range minus 1.0 percent (weight loss) to plus 5.0 percent (weight gain) (see 4.5.6). 3.4.5 Chloride content. The chloride content of the abrasive shall be less than 0.03 percent by weight (see 4.5.7). 4 Provided by IHSNot for Resa
