14、tandard sample. A standard sample of indicator solution will be supplied by the Government on request by a potential bidder. The standard sample will be furnished only to show the potential bidder the color (obtained when 0.5 milliliter (mL) of standard sample is added to 15 mL of each buffer soluti
15、on prepared in accordance with 4.2.2) that the indicator solution he proposes to furnish must produce (see 6.4). 3.3 Material. Material shall be as specified herein. Material not specified shall be selected by the contractor and shall be subject to all provisions of this specification. 3.3.1 Suspend
16、ed matter and foreign material. Total suspended matter and foreign material shall not exceed 10 mg/L when tested per 4.2.1. When specified (see 6.2), the contractor may certify that the indicator solution has been filtered through Whatman grade 934AH and 984H, Gelmen type A/E, Millipore type AP40, o
17、r equivalent glass fiber filters prior to packaging. 3.4 Government-loaned property. Unless otherwise specified (see 6.2), the following property conforming to MIL-D-537, type I, class 8, in the quantities indicated will be loaned by the Government (see 6.3): Item No. Description Quantity 1 Disk, ma
