The kit consists of a plastic sample with breaking device, evacuated ampoules containing test chemicals, an

14、d high and low range color comparators. 3.2 First article. When specified (see 6.2), a sample shall be subjected to first article inspection (see 6.4) in accordance with 4.2.1. 3.3 Characteristics. 3.3.1 Performance.

The value obtained shall be equal to the readable value nearest to the actual hydrazine level of the sample or to the next readable value above or below this value. Both comparators shall read O when no hydrazine is present. A readable value is defined as equal

17、to the value of a color standard, the average of two adjacent color standards, or greater than the highest color standard. 3.3.2 Physical characteristics. 3.3.2.1 Component parts. The hydrazine test kit shall consist of the following: (a) One low range colorimetric comparator. (b) One high range col

26、t ampoules used in determining the hydrazine content shall be as shown on figure 3. They shall be made of glass, flat on one end and drawn to a tapered hermetically sealed closure at the other end. The tapered end shall be scored so that it breaks easily and evenly. A color-forming reagent shall be

27、contained in each ampoule. This color- forming reagent shall be clear to pale yellow in color with no sediment present. The ampoule shall contain a vacuum so it will self fill when placed in the sample to be tested and the tip is broken. When filled, the ampoule shall contain the sample and reagent.

28、 A small inert gas bubble shall be present in the broken ampoule to facilitate mixing of the sample and reagent. The ampoules shall be packaged 30 to a box with each ampoule in an individual paper divider to hold the ampoules in an orderly manner and to provide some cushioning as shown on figure 3.

The sample cup shall provide a reservoir for the sample into which the ampoule may be placed, such that whe

30、n the tip of the ampoule is broken, sample will be drawn into the ampoule. The sample cup shall be fabricated from clear plastic, at least 1 mm thick, and require no more than 30 mL of sample. The breaking device shall be an integral part of the cup. The cup shall rinse easily to prevent cross conta

31、mination of the samples. 3.3.2.1.5 StoraRe case. The storage case shall be of corrosion resistant material (that is, plastic or coated steel) with individual compartments for each component of the test kit. Each item in the kit shall be accessible without having to remove another item. The kit shall

32、 provide protection against breakage during normal handling. Packing material shall be used inside the case to prevent breakage during shipment. The case shall close securely using a snap or latch 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-I .

QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contra

36、ctor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements spe

37、cified herein, unless disapproved by the Government. The Govern- ment reserves the right to perform any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for complian

38、ce. All items shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the r

39、esponsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of the manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not au

40、thorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.2 Classification of inspections. The inspection,requirements specified herein are classified as follows: (a) First article inspection (see 4.2.1). (b) Quality
