1、Designation: E1157 87 (Reapproved 2011)Standard Specification forSampling and Testing of Reusable Laboratory Glassware1This standard is issued under the fixed designation E1157; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the y
2、ear of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers labo
3、ratory items for use untilthey are no longer considered functional for the intendedpurpose. It is written specifically for reusable items and is notto be confused with disposable (single use) items that aredescribed in other standards.1.2 This specification covers the sampling inspection andbasic te
4、sting criteria for the following four types of laboratoryglassware: blown and pressed glassware, nongraduated;2blown and pressed glassware, graduated;2tubular glassware,nongraduated; and tubular glassware, graduated.1.3 This specification is intended to be used in conjunctionwith a standard specific
5、ation for a specific laboratory glasswareproduct.1.4 The following precautionary statement pertains only tothe test method portion, Section 6, of this specification. Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the u
6、serof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.

Deviation from or changes to established manufac-turing procedures that could adversely affect performance of aproduct shall be cause for performing applicable testingrequirements on a specific lot to verify quality acceptance.4.2 Alternate testing methods, inspection levels, and sam
17、plesizes may also be implemented. Any deviation shall not negateresponsibility of product from complying with the applicabletest performance standards.4.3 Unless otherwise specified in the contract or purchaseorder, the supplier shall be responsible for the performance ofall designated inspection re
18、quirements. Except as otherwisespecified in the contract or purchase order, the supplier may usehis own or any other facilities suitable for the performance ofthe inspection requirements. The purchaser has the right toperform any of the inspections set forth in the specificationwhere such inspection
19、s are deemed necessary to ensure sup-plies conform to prescribed requirements.5. Sampling and Inspection5.1 Sampling shall be conducted in accordance with MIL-STD-105 with the levels of inspection and examination andacceptable quality levels as noted in Tables 1-13 unlessotherwise agreed upon by pur
20、chaser and vendor. Where appli-cable, distilled water and reagent grade chemicals shall be usedthroughout the tests. Inspection shall be conducted in accor-dance with applicable section and individual specifications.6. Test Methods6.1 Leakage TestThe item shall be filled to nominalcapacity with dist
21、illed water at 25 6 5C, normally capped orstoppered and laid on side for 60 s. No leakage shall result.6.2 Permanency of Marking:6.2.1 Alkali TestA representative piece of each sampleshall be completely immersed in 1 N sodium hydroxidesolution at room temperature, covered, boiled for 30 min, andallo
22、wed to stand in the alkali for an additional hour. The pieceshall then be removed, thoroughly rinsed with distilled water,and dried by rubbing vigorously with a cloth. No appreciablechange in decoration appearance shall result. Loss of glossshall not be considered a defect.6.2.2 Acid TestArepresenta
23、tive piece of each sample shallbe completely immersed in concentrated sulfuric acid at roomtemperature and allowed to stand 1 h. The piece shall then beremoved, thoroughly rinsed with distilled water, and dried byrubbing vigorously with a cloth. No appreciable change indecoration appearance shall re

Loss of gloss shall not beconsidered a defect.6.3 Capacity:6.3.1 Blown or Pressed Items (Nongraduated) and TubularGlassware (Nongraduated)Avolume of distilled water equalto the capacity specified for the size shall be added to the item.The water level shall be between the shoulder and the neck
25、 ofthe item or at the approximate point indicated in the specificstandard for the item. The test shall be conducted at roomtemperature (25 6 5C).6.3.2 Blown or Pressed Items (Graduated) and TubularGlassware (Graduated)Accuracy shall be as defined inappropriate item standard. Testing shall be conduct
26、ed inaccordance with procedures in Practice E542.6.4 AutoclavingItems with respective cap or cover se-cured shall be subject to three consecutive autoclaving cyclesat 15 psi for 30 min. Capped items shall be removed after eachautoclaving cycle and allowed to cool for 30 min beforerepeating the heati
27、ng cycle.Autoclaved items with cap or covershall be subjected to leakage test. Temperature shall be 121C.6.5 Pour TestFill the item to normal capacity with dis-tilled water. Tilt at an angle of 45 and pour approximately onefourth of the water from the item at such a rate that the waterflows in a con
28、tinuous stream and falls freely from the spout.Stream of water should not cling to the outside of the item andflow off the bottom.6.6 Centrifuge TestThe centrifuge may be any type ormodel commercially available or normally employed in labo-ratories and capable of speeds (RPM) recommended for theitem
29、. Item shall be filled with tap water to appropriate capacityand placed in centrifuge in balance positions. The centrifugeshall be brought slowly up to recommended speed and run for30 min. The centrifuge shall then be shut off and allowed tostop without use of the hand brake. There shall be no break
