1、Designation: F3188 16Standard Specification forExtractable Hazardous Metals in Synthetic Turf InfillMaterials1This standard is issued under the fixed designation F3188; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of la

2、st revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification relates to the amount of certain metalsthat have the potential to be extracted from synthetic turf in

3、fillmaterials if ingested. The time, temperature, and pH of theextraction fluid approximate the conditions the infill materialwould experience in the stomach during the digestive process.The levels of extractable metals are compared to maximumlevels allowed in childrens toys.1.2 This specification a

4、pplies to all materials (man-made ornatural) that are intended for use as infill materials for syntheticturf sports surfaces.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all o

5、f thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

10、content of hazardous metals shall not exceed thelevel shown in Table 1.TEST METHODS5. Summary of Test Method5.1 The synthetic turf infill soluble hazardous metal contentis determined using a procedure contained in Consumer SafetySpecification F963. This procedure simulates the situation inwhich synt

United States16. Sampling6.1 The labor

15、atory sample of infill material is a representa-tive sample of at least 100 g collected from a synthetic turf fieldor from a super sack or infill container.7. Significance and Use7.1 This test method is based on subsection 8.3 of ConsumerSafety Specification F963, which specifies a test procedure to

16、determine the amount of hazardous metals that have thepotential to be present in toys and handled or ingested bychildren. Since it is possible for users of synthetic turf playingsurfaces to handle or ingest particles of synthetic turf infillmaterials, it is necessary to determine the level of hazard

17、ousmetals in the synthetic turf infill materials. The limits ofhazardous metals used in this specification are based on thosespecified in Consumer Safety Specification F963, adjusted forstatistical error correction factor as described in ConsumerSafety Specification F963.8. Apparatus8.1 pH Meter, ac

Unless otherwise indicated, it is intended thatall reagents conform to the specifications of the Committee onAnalytical Reagents of the American Chemical Society wheresuch specifications are avai

20、lable.5Other grades are permitted,provided it is first ascertained that the reagent is of sufficientlyhigh purity to permit its use without lessening of the accuracyof the determination.9.2 Hydrochloric Acid Solution, 0.08 mol/L.9.3 Hydrochloric Acid Solution, 2.0 mol/L.9.4 Purity of WaterUnless oth

21、erwise indicated, referenceto water shall be understood to mean reagent water as definedby Type 3 of Specification D1193.10. Procedure10.1 From the laboratory sample (6.1) of infill material,select a test portion of at least 100 mg10.2 Mix the test portion with 50 times its mass of anaqueous solutio

22、n of 0.08-mol/L hydrochloric acid at 37 6 2C.Shake for 1 min.10.3 Measure the pH of the mixture. If the pH is greater than1.5, add drop-wise while shaking an aqueous solution of 2mol/L (7.3 %) hydrochloric acid until the pH is between 1.0and 1.5. Protect the mixture from light. Continuously shake th

23、emixture for 1 h and allow to stand for1hatatemperature of37 6 2C.NOTE 1It has been shown that the extraction of soluble cadmium canincrease two to five times when extraction is conducted in the light ratherthan in the dark.10.4 Without delay, separate the solids from the mixture byfiltering through

24、 a membrane filter with a pore size of 0.45 m.If necessary, centrifuge at 5000 6 500 rpm for no longer than10 min. Analyze the solution using EPA Methods 7470A and6010B to determine the present of the elements listed in Table1.10.5 If it is not possible to analyze the sample within oneworking day, s

26、ples in 10.7. This is necessary tomake statistical correction for interlaboratory error.10.7 Example of Calculations Using Table 2:10.7.1 Example 1The analytical result for lead is 120mg/L; the correction factor from Table 2 is 30 % (0.30).Adjusted analytical results = 120 (120 0.30) = 120 36 =84 mg

27、/L. The result does not exceed the value for lead in Table1 and is therefore acceptable.10.7.2 Example 2The analytical result for chromium is 90mg/L; the correction factor from Table 2 is 30 % (0.30).5Reagent Chemicals, American Chemical Society Specifications, AmericanChemical Society, Washington,
