REQUIREMENTS 3.1 First article. The indicator cards furnished u
8、nder this specification shall be products which have been inspected and passed the first article inspection specified herein (see 4.3 and 6.2). Indicator cards shall be approved only for the materials and design for which first article inspections are made. Any changes shall be cause for designating
9、 the indicator card as a new product which shall not be considered as approved. The changed indicator card shall be resubmitted for approval under this specification. 3.2 c hemi ca 1 manually Material. The indicator card shall consist of an isolated agent and an indicating strip packaged as a single
10、 unit. When activated, the chemical agent shall cause the indicating strip to integrate time and temperature by showing a distinct color change which shall progress along the length of the strip at a temperature controlled rate in accordance with 3.5. 3.3 Design. The time-temperature indicator shall
11、 be designed in accordance with Figure 1. 3.4 Dimens ions. 3.4.1 cards shall be Indicator cards.

13、quare. 3.5 Reactivity. The reactivity of the time-temperature indica- tor is defined as the rate (time-units) at which the indicator changes color at a given temperature. The time taken for the indicator to show a maximum reading (color change through the length of the indicator) shall be determined
14、 at the temperature given in Table I for a particular class and at a relative humidity of 50 percent. TABLE I Reactivity I I Class I Days to maximum reading I I I 1 1 3.5.1 Time-temperature graph.

The time-temperature indicators covered by this specification are intended to be packaged with products having a limited shelf-life and which are temperature sensitive. The indicators should not be exposed to direct sunlight. Relative humidity in
38、 excess of 50 percent will slightly decrease the reactivity of the indicators. 6.1.1 Time-temperature graph. The time-temperature graph for each class of indicator card is utilized in the establishment of the product end point. 6.2 Ordering data. Acquisition documents should specify the following: a
39、. b. c. Total Quantity required d. e. Title, number and date of this specification. Class of indicator card required (see 1.2) Levels of packaging and packing required (see 5.1) Items of data required (see 6.3) 6.2.1. First article. When a first article is required for in- spection and .approval (se
40、e 3.1, 4.3, 6.2 and 6.3), the contracts or orders should specify the following provisions for first article in- spection. When a contractor is in continuous production of indicator cards from contract to contract, consideration should be given to waive the first article inspections, If inspection is
41、 required, indicate: If first article inspections are conducted at the contractors plant or a government approved laboratory, an inspection report should be forwarded to the acquiring activity for veri- fication. a. b. That the approval of first article samples or the waiving of the first article in
42、spection should not relieve the contractor of his obligation to fulfill all other requirements of the specification and contract. 8 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-4 DOD-1-85390 66 9779706 01115217 7 W DoD-1-85390 6.3 Contract data re
