16、uct conformity assessment. This standard is specified in each IEC product standard for live working for the purpose of assessing that products having completed the production phase meet the requirements of the relevant product standard. It can be used as a basis for production certification. TC 78 p
17、repares product standards which include requirements and normative tests for design input (type tests). Product conformity assessment elements related to the production phase (among them is the procedure to associate routine and sampling tests to the classification of defects) are included in the pr
18、esent standard. This publication does not cover conformity of commercial shipments. Shipments can contain products coming from several production batches. Batches are here understood as related to production. This publication is not a quality management systems standard. BS EN 61318:2008 4 LIVE WORK
19、ING CONFORMITY ASSESSMENT APPLICABLE TO TOOLS, DEVICES AND EQUIPMENT 1 Scope This International Standard provides elements for product conformity assessment. Critical defects on tools, devices and equipment for live working are not acceptable. Major defects on tools, devices and equipment for live w
20、orking are likely to result in failure or in a significant reduction of functionality, while minor defects do not reduce significantly the functionality. This standard defines assessment methods for products having completed production phase to assure that they conform to the requirements of the cor
21、responding product standard. It is to be used in conjunction with live working corresponding product standards. The following elements are not covered by the present document, but are included in each product standard: type tests; provisions and description for sampling and routine tests; the identi
22、fication and classification of the corresponding defects resulting from a risk analysis. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、16-16, modified 4 General The conformity assessment of every finished tool, device and equipment having completed the production phase can be achieved by the application of the provisions of this standard. Alternative test methods based on quality and safety assessment (see Annex B) are acceptable i
35、f they warrant the same level of conformity and safety and are validated by a “responsible authority”. NOTE Where appropriate, the product standards should include alternative test methods when the methods specified at the type test level are found less or not practicable at the production level. Ne
36、vertheless, it could happen that a test method provided in the product standard is not found adequate by a manufacturer. In such case, the present standard permits to replace this test by another equivalent alternative test. These alternative test methods shall be justified, described, maintained an
37、d recorded. NOTE To justify an alternative test method the manufacturer will have to provide objective evidence that it warrants the same level of conformity and safety. In any cases test results shall be recorded and kept by the manufacturer in accordance with national or regional regulations but n
38、ot less than five years. 5 Categories of tests 5.1 Overview Four categories of tests are currently included within live working product standards: BS EN 61318:2008 7 type tests (not covered by this standard), routine tests (see 5.2), sampling tests (see 5.3), acceptance tests (see 5.4 and Annex A).
39、This standard is intended to be used for managing routine and sampling tests in the purpose of conformity assessment during the production phase. This standard provides an informative annex related to acceptance tests. NOTE Other tests may be included in the conformity assessment documentation for e
40、xample, tests recommended for use during production to monitor the production process, but they are not covered by this standard. 5.2 Routine tests Routine tests shall be performed to avoid critical defect. An annex within each product standard identifies critical defects and associated tests (see a
41、 typical example in Annex C). To be in accordance with the present standard, these tests or alternative test methods as specified in Clause 4 shall be used as routine tests. 5.3 Sampling tests Sampling tests shall be performed to avoid major and minor defects. An annex within each product standard i
42、dentifies major and minor defects and associated tests (see a typical example in Annex C). To be in accordance with the present standard, these tests or alternative test methods as specified in Clause 4 shall be used as sampling tests. Sampling procedures and the validation of test results shall be
43、in conformance with Clause 6. 5.4 Acceptance tests Annex A provides guidance on the use of acceptance tests at customers request within the frame of a commercial contract. 6 Sampling procedure The sampling procedure is based on the availability of non-destructive sampling tests. When the tests propo
44、sed within the product standard are destructive, the manufacturer could propose if possible alternative non-destructive test methods according to Clause 4. The manufacturer shall define a sampling plan, using the rules of ISO 2859. According to the nature of the product and the lot size, the manufac
45、turer will select the more appropriate sampling parameters while respecting the following: major defects : AQL 2,5; minor defects : AQL 4. BS EN 61318:2008 8 Annex A (informative) Acceptance test An acceptance test is a contractual test to prove to the customer that the item(s) or product in questio
46、n meet(s) the customers specification. If the customer requests additional tests or increase of the stringency of the sampling procedure this should be acceptable after agreement between the customer and the supplier. In that case the customer should include this within his own specification. The di
47、sposition of tested products should be considered. If a test is destructive the product should be re-built, if possible, or destroyed to insure that worker safety is not jeopardized from the later use of a damaged product. If the test is non-destructive and the products are not damaged, they could b
48、e (or not) included in the customer order as a normal part of the order. BS EN 61318:2008 9 Annex B (informative) Recommendations for developing and applying equivalent alternative test methods The development of an equivalent alternative test method should consider the elements of risk analysis of
49、product defects provided by the product standard: description of the requirements the product has to meet; determination of the classification of defects (critical, major, minor); definition and statement based on the classification of defects of adequate requirements and relevant means (test, inspection, calculation, etc.). The alternative test methods developed should provide consistent results and ensure the reproducibility of the results. The accuracy of the chosen
