  1. pbw: Percent by weight.
  1. One (1) mil sprayed coating on a 4-1/2" x 7-1/2" x 1/32" cold rolled steel panel, dried for eighteen (18) hours at 77 ° ± 6 °F (25é ± 2 °C), then baked for one (1) hour at 221 ° ± 2 °F (105 ° ± 1 °C), and bent on a 1/4" mandrel.

3.3. Working Properties: The paint as received shall have satisfactory brushing properties, and shall not run or sag when applied to a vertical surface. Then thinned in accordance with label instructions, it shall spray satisfactorily in all respects, particularly with regard to freedom from running, sagging, or streaking.

3.4. Storage Stability:

3.4.1. Partially Filled Containers: When tested in accordance with Method 3021, Federal Test Method Standard 141B and Paragraph of Federal Specification TT-P-28F, a 300-ml sample of the pain shall show no livering, curdling, or caking of pigment within forty-eight (48) hours at 21--32 °C. Any skin forming on the surface shall be continuous and easily removed.

3.4.2. Full Container: A sample of the paint shall be left undisturbed for one (1) year in a full, tightly closed one (1) quart paint can. At the end of this period, it shall be opened for examination of the contents. There shall be no significant pressure buildup in the can. The sediment layer shall contain in grainy, gummy or gelatinous matter which is not readily dispersible to a smooth, homogeneous state, either by stirring or by five (5) minutes on a paint shaker. The viscosity of the paint after re-dispersion shall not exceed 90 KU.

4. SAMPLES: Unless otherwise specified in the Invitation for Bids, predelivery samples will not be required. Samples for testing shall be taken from the finished product either at the place of manufacture or at the destination. The Commission reserves the right to take samples of the raw materials for testing, either before or during the manufacturing process.

5. TESTING: Testing shall be done at the direction of the Commission on samples taken at the place of manufacture or from shipments on regular or scheduled orders. In the event that the pain tested fails to meet all conditions and requirements of this specification, the cost of the testing shall be borne by the supplier. Testing shall be performed by the methods cited in Paragraph 3, or by approved equally applicable procedures.

6. INSPECTION: Inspection shall be done by or at the direction of the Commission, either after delivery or at the place of manufacture. Should latent defects be discovered in material from a previously unopened container with one (1) year from date of delivery, the State of Texas shall have the option of either requiring replacement or rejecting further shipments and canceling the purchase order or contract. In the event that the second option is exercised, the vendor or contractor shall reimburse the State of Texas for any expenses resulting from the cancellation and from securing satisfactory replacement paint.

7. PACKING and/or PACKAGING: The pain shall be furnished in new, well sealed metal containers which not only meet DOT requirements, but also are strong enough to withstand a normal amount of rough handling in transit. Rusty and/or bent containers are not acceptable. Type and size of container shall be one or more of the following, whichever is specified in the Invitation to Bid.

7.1. One (1) gallon cans with bail, packed in the manufacturer's usual shipping carton.

8.5. Month and year of manufacture.

8.6. Precautionary statement (Must meet the requirements of Federal and State regulations.)

9. COMPLIANCE: In order for consideration to be given to the bid on an item under this specification, the bidder must comply with the following conditions.

9.1. Equipment Identification: The make, model number, name of the manufacturer, brand or trade name, etc., as applicable, of the item which the vendor proposes to furnish must be state as part of the bid.

9.2. Exceptions: Notwithstanding the above, any exception taken by the bidder to the requirements and conditions of this specification must be stated and described in detail as a part of the bid. If no exceptions or deviations are identified in this manner, the items must be furnished exactly as described herein.

9.3. Proof: The bidder shall bear the burden of proof of compliance with this specification.

10. ORDERING DATA: When ordering paint conforming to this specification, the requisitioning agency must specify the following:

10.1. The number of this specification (630-51-03A).

10.2. The quantity required.

10.3. The size of container required.

11. PRODUCT INFORMATION: This specification allows considerable latitude in product composition. However, aluminum paints are generally formulated with a high proportion of volatile organic solvent. the use of this paint in certain areas of the state may consequently come under restriction in accordance with Regulation V (See Paragraph 2.3.). The ordering agency should verify in advance with the Texas Natural Resource Conservation Commission (TNRCC) that a product conforming to this specification is legally acceptable in the area where it is to be used. Note: Follow the label instructions for safe handling and use.
