It is written in SI (metric units and supersedes the previous edition published in 1984. recog

The categories are described as follows: (a) Category 1: These fluids are the most fire resistant and show no measurable flams persistence in the flammability tests specif

29、ied in this Standard. (b) Category 2: These fluids are not as fire resistant as the fluids in Category 1 but still meet the flammability tests (with longer flame persistence) specified in this Standard. (c) Category 3: These fluids are considerably more fire resistant than mineral oils but are only

30、required to pass the spray flammability test in this Standard. They are usually compatible with systems designed to use mineral oil. of Mines for a Standard to cover the safety aspects of hydraulic fluids, which are used extensively in the hydraulic systems of mining machinery. (a) Clause 4.3, Fluid

31、 Stability: The acceptable oil separatioia for water in oil emulsions has been decreased from 3% to 2%. (b) Clause 4.4, Toxicity: This Clause has been expanded to include detailed criteria on acute toxicity, acute skin irritation, acute eye irritation, sensitization, and chronic toxicity. (c) Clause

32、 5.1, Preconditioning Test: The preconditioning test is now to be carried out only on non-aqueous hydraulic fluids. (d) Clause 5.4.3, Freeze-Thaw Stability Test: The number of cycles of exposure completed in this test has been increased from two cycles to seven cycles. This Standard was prepared by

33、the Technical Committee on Fire Resistant Hydrau!ir Fluids under the jurisdiction of the Standards Steering Committee on Electrical and Mechanical Mine Safety, and was formally approved by these Committees. It has been approved as a National Standard of Canada by the Standards Council of Canada. May

34、 1987 This Standard divides hydraulic fluids into three categories. The reasons for this are to This Standard has been prepared as a result of a request f, ,m the Provincial Inspectors The major changes from the 1984 edition of M423 concst nf the following: Notes: (1) Use of the masculine gender in

35、this Standard is not meant to exclude the feminine gender. Similarly, use of the singular does not exclude the plural (and vice versa) when the sense allows. (2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibil

36、ity of the user of the Standard to judge its suitability for his particular purpose. (3) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee. (4) All enquiries regarding this Standard, including requests for interpretation

37、, should be addressed to Canadian Standards Association, Standards Division, 178 Rexdale Boulevard, Rexdale, Ontario M9 W 1 R3. Requests for interpretation should (a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch: (b) provide an e

Scope 1 .I This Standard covers the fire resistance, toxicity, and stability with respect to separation of water-in-oil emulsions of

40、 hydraulic fluids intended for use at mines. 1.2 This Standard covers fluid in the following categories: (a) Category l-fluid that shows no measurable flame persistence (ie, less than 1 s) in either of the flammability tests specified in this Standard; (b) Category 2-fluid that passes both the spray

41、 and wick flammability tests specified in this Standard; (c) Category 3-fluid that passes the spray ignition test specified in this Standard but may not be capable of passing the wick test. 1.3 This Standard does not cover products of combustion or products of thermal degradation from hydraulic flui

42、ds subjected to fire or heating. Note: While the object of this Standard is to establish a reasonable level of fire resistance for hydraulic fluids, it is recognized that any hydraulic fluid may burn under conditions different from those described in this Standard. 2. Definitions 2.1 The following d

43、efinitions apply in this Standard: Fire resistant (as applied to hydraulic fluids)-a fluid that will meet the fire resistance tests specified in this Standard. LD, (median lethal dose) dermal-a statistically derived single dose of a substance that can be expected to cause death in 50% of treated ani

44、mals when applied to the skin. LD, (median lethal dose) oral-a statistically derived single dose of a substance that can be expected to cause death in 50% of treated animals when administered by the oral route. 3.
