1、Designation: E 921 97 (Reapproved 2003)Standard Specification forExport Packaged Laboratory Apparatus1This standard is issued under the fixed designation E 921; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revis
2、ion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis specification is proposed as a performance standard to be met for items that will be exported.The standard would apply onl
3、y when requested by the buyer.1. Scope1.1 This specification covers the procedures for testingloaded shipping containers. Drop, vibration and compressiontests are performed to measure the ability of the shippingcontainer to protect the product from shock, vibration andcompressive forces encountered
4、during normal export handlingand shipping conditions. This specification is not intended tosupplant material specifications or existing preshipment testprocedures. This specification is not intended for use withhazardous materials.1.2 These procedures are suitable for all types of laboratoryapparatu
5、s, including reusable and disposable macro and microproducts.1.3 The following precautionary caveat pertains only to thetest method portion, Section 4, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility
6、 of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.
