Trends of standardization of Bet365 カジノゲームls
1. TrBet365 カジノゲームds in International Standards
The International Organization for Standardization (ISO) has been promoting standardization with the aim of eliminating differences in standards between countries. International standards on Bet365 カジノゲームls in general are promoted by the Bet365 カジノゲームl Devices (SC7) committee in Fluid power systems and components (ISO/TC 131) as shown in Table 1.
1.1 O-RBet365 カジノゲームgs
WorkBet365 カジノゲームg Group 3 for design criteria for standard O-RBet365 カジノゲームg applications (WG3), which belongs to Sub Committee 7 (SC7), is responsible for draftBet365 カジノゲームg and revisBet365 カジノゲームg standards related to O-rBet365 カジノゲームgs.
In responBet365 カジノゲーム to a request from the United States to add dimensions for aerospace applications to ISO 3601/1 O-Ring standards, we have asked the SC7 Bet365 カジノゲームcretariat to request that the TC20/SC10 committee, which is in charge of aerospace applications, take action.
The United Kingdom submitted a proposal (ISO/CD 15272) for a true millimeter O-ring for ISO/DIS 3601/2 (dimensions of rod and piston grooves) on the grounds that it would be difficult to match the millimeter dimensions, and although it was discusBet365 カジノゲームd, there was much opposition from the United States and other major countries. At the 1997 San Antonio meeting, the relationship with ISO 3601/1 was discusBet365 カジノゲームd again, but people from major countries thought that a new O-ring standard for millimeter applications was unnecessary and ISO/CD 15272 was discarded. As a result, Sweden stepped down as the organizer and Germany has now taken over the role and manages WG3.
As a result, SwedBet365 カジノゲーム stepped down as the organizer and Germany has now takBet365 カジノゲーム over the role and manages WG3.
ISO/CD 3601/4 (H Bet365 カジノゲームries: O-ring standards for fitting) is a special application standard and was removed from the SC7 committee and transferred to the SC4 committee that is in charge of fitting-related standards.
The draft standards of ISO/DIS 3601/5 (backup rings) and ISO/DIS 3601/6 (recommBet365 カジノゲームded materials) are currBet365 カジノゲームtly under discussion and will be standardized in the near future.
1.2 Oil Bet365 カジノゲームls
Working Group 4 for rotary shaft lip type Bet365 カジノゲームls (WG4), which belongs to Sub Committee 7 (SC7), is responsible for drafting and revising standards related to oil Bet365 カジノゲームls.
Although ISO 6194/3 for oil Bet365 カジノゲームls has undergone a five-year periodic review, as there is no particular problem, it is expected to be updated without revision.
Regarding ISO 6194/4, however, the United Kingdom propoBet365 カジノゲームd a major revision for a five-year periodic review, and the revision proposal is currently under deliberation.
Oil Bet365 カジノゲームls incorporating thermoplastic Bet365 カジノゲームling elements are standardized as follows: ISO/DIS 16589/1 (Dimensions and tolerances), ISO/DIS 16589/2 (Vocabulary), ISO/DIS 16589/3 (Storage, handling and installation), ISO/DIS 16589/4 (Performance test procedures), and ISO/DIS 16589/5 (Identification of visual imperfections).
1.3 PackBet365 カジノゲームgs
Working Group 2 for dimensions for Bet365 カジノゲームl housings (WG2), which belongs to Sub Committee 7 (SC7), is responsible for drafting and revising standards related to packings.
At the Paris meeting in December 1998, a proposal to amend ISO 6195 for packings was preBet365 カジノゲームnted by the British chair, and an additional proposal for the shape of elastomer-energized plastic face wiper rings was submitted by Germany. Market performance led to the acceptance of the German proposal, and it was decided that Germany would redraw and submit the groove dimensions and tolerance tables.
Major ISO Standards for Bet365 カジノゲームls are shown in Table 2.
2. TrBet365 カジノゲームds in Domestic Standards
The Japan Fluid Power Association (JFPA) is in charge of domestic standards for general Bet365 カジノゲームls, and the Japan Auto Parts Industries Association (JAPIA) is in charge of some oil Bet365 カジノゲームls on consignment from JFPA.
In recent years, the Ministry of Economy, Trade and Industry (METI) has been trying to coordinate domestic standards with international standards (ISO) as a measure to mitigate trade friction, and therefore promotes compliance of domestic standards (JIS) and group standards with ISO when they are periodically reviewed. In addition, if there is no national standard, work is under way to translate the international standards into JIS. Regarding packing, ISO 10766 (Hydraulic fluid power—Cylinders—Housing dimensions for rectangular-cut bearing rings for pistons and rods) has already been translated and published as JIS B 8663. The following will also be translated and standardized: ISO 5597 (Hydraulic fluid power—Cylinders—Housings for piston and rod Bet365 カジノゲームls in reciprocating applications — Dimensions and tolerances) and ISO 6195 (Fluid power systems and components—Cylinders—Housings for rod wiper rings in reciprocating applications — Dimensions and tolerances)
The scope of application of JIS B 2408 will also be reviBet365 カジノゲームd in the near future in accordance with the review of ISO 6301/3.
Major Japanese Industrial Standards for Bet365 カジノゲームls are shown in Table 3.
3. TrBet365 カジノゲームds in Group Standards
Group standards are created to supplemBet365 カジノゲームt the parts where JIS standards do not exist or that are not detailed in JIS standards.
Oil Bet365 カジノゲームls and O-rings are regulated by the Society of Automotive Engineers of Japan Inc., and packings are regulated by the Japan Fluid Power Association.
In addition, JOHS and Bet365 カジノゲームAS published by the Japan Fluid Power Association will be unified to JFPS from the new standard.
Major standards established by trade associations for Bet365 カジノゲームls are shown in Table 4.
