1、I MSS SP-100-2002 Qualification Requirements for Elastomer Diaphragms for Nuclear Service Diaphragm Valves Standard Practice Developed and Approved by the Manufacturers Standardization Society of the Valve and Fittings Industry, Inc. 127 Park Street, NE Vienna, Virginia 22180 (703) 281 -661 3 MSS ST
2、ANDARD PRACTICE SP-1 O0 This MSS Standard Practice was developed under the consensus of the MSS Technical Committee 406 and the MSS Coordinating Committee. The content of this Standard Practice is the result of the efforts of compe- tent and concerned volunteers to provide an effective, clear, and n
3、on-exclusive specification that will benefit the industry as a whole. This MSS Standard practice is intended as a basis for common practice by the manufacturer, the user, and the general public. The existence of an MSS Standard Practice does not in itself preclude the manufacture, sale, or use of pr
4、oducts not conforming to the Standard Practice. Mandatory conformance is established only by reference in a code, specification, sales contract, or public law, as appli- cable. Substantive changes in this 2002 edition are “flagged” by parallel bars as shown on the mar- gins of this paragraph. The sp
5、ecific detail of the changes may be determined by comparing the material flagged with that in the previous edition. Unless otherwise specifically noted in this MSS SP, any standard referred to herein is identified by the date of issue that was applicable to the referenced standard(s) at the date of

9、1. SCOPE This Standard Practice delineates a method for quali- fication of elastomer diaphragms, in accordance with methodology and documentation as described in Ap- pendix QR-B of ASME QME-1, that are intended for use in ASME Boiler and Pressure Vessel Code, Section III, Classes 2 and 3 diaphragm v
10、alves. In addition, this Standard Practice establishes methods for production verification and for the development of service limits for elastomer diaphragms. 2. OUALIFICATION 2.1 The valve manufacturer shall prepare a test plan that details the procedures used to comply with the required tests of S
11、ection 2.2. The test plan shall state the rationale used to select the thermal aging temperature and time, radiation aging total dose, and pressure and temperature for the wear aging or cycle life test. 2.2 A specific diaphragm size, compound, design, and construction may be qualified by type testin
12、g. For each qualification step, testing shall be conducted on representative production diaphragms from the same batch. This type testing shall include: 2.2.1 Thermal aging to qualiS, for a minimum period of time, as specified in Section 4.0. The thermal aging test may be based on the Arrhenius Law
13、to determine aging time and temperature. 2.2.2 Radiation aging to a total dose levei at least equal to the requirements of the Design Specifica- tion or a dose level equivalent to the service life, as specified in Section 4.0. 2.2.3 Wear aging to quaiiS, the elastomer diaphragm for the service life
14、limitations specified in Section 4.0. The wear aging test shall include the effects of pressure, temperature, and cycles, simultaneously. 2.3 Each size diaphragm shall be subjected to a baseline life cycle test at a pressure and tempera- ture established by the valve manufacturer. This test data wil
15、l be used to establish acceptance criteria for production lot cyclic test specified in Section 3.1.4. 2.4 Thermal aging and wear testing conducted at two different pressurehemperature combinations may be used to qualify the diaphragm for all conditions enveloped by the two points with equal or less
16、radia- tion exposure. 3. PRODUCTION REQUIREMENTS 3.1 To verify that production diaphragms are equivalent to diaphragms qualified by the procedures for Section 2.0, the following minimum requirements shall be met: 3.1.1 Certification of compound by Certificate of Compliance from diaphragm manufacture
17、r for each batch. 3.1.2 Verification of tensile strength, modulus, and elongation properties for each batch of the elastomer compound per ASTM D 412. 3.1.3 Production lot visual, dimensional, and durom- eter examination to sampling procedure in accordance with ANSI ASQC Z1.4, General Inspection Leve
18、l III, AQL 0.40. In addition, all diaphragms for valves over NPS 2 shall be durometer tested in accordance with ASTM D 2240. 3.1.4 Cycle test one diaphragm from each produc- tion lot in accordance to the life cycle test estab- lished in Section 2.3. 1 -,-,- MSS STANDARD PRACTICE SP-1 O0 4. SERVICE L
19、IMITATIONS 4.1 Service limitations shall include limitations on diaphragm flexure cycles (full stroking, close-open- close or open-close-open), time in service and stor- age life as follows: 4.1.1 The required diaphragm cycle/flexure life shall not exceed 1/3 the minimum cycle life established by th
20、e requirements of Section 2.0. 4.1.2 The service life of the elastomeric diaphragm shall not exceed five years, and the combined ser- vice and storage life of the diaphragm shall not ex- ceed ten years. 5. MARKING manufacturers identification symbol, and elastomer compound identification code or bat
21、ch code. 6. DOCUMENTATION 6.1 The testing performed in accordance with the requirements of Section 2.0 shall be documented in a test report that shall include the test plan. 6.2 An applications report shall be prepared to show the suitability of the specific diaphragm for service defined by a Design
22、 Specification. 6.3 In lieu of compliance with service life required by the Design Specification, the applications report shall recommend the required diaphragm replace- ment life or qualified service life based on time and/ or cycles based on the data in the test report. 5.1 the month and year of m
