FORD LABORATORY TEST METHOD BO 131-03 Copyright 2014, Ford Global Technologies, LLC Page 3 of 7 Conditioning of Materials and Test Conditions All test values indicated he
14、rein are based on material conditioned in a controlled atmosphere of 23 2 C and 50 5% relative humidity, for not less than 24 hours prior to testing, and tested under the same conditions unless otherwise specified. All parts or samples should be wrapped/bagged 14 - 28 days after part manufacture wit
15、h one of the following: heat sealed polyethylene (PE) bags, clean plastic wrap foil (PE or PP), PE coated aluminum bags or aluminum foil. Parts that are only to be used in the China market and regionally sourced should be wrapped/bagged 7-14 days after part manufacture. Parts for testing must be lab
16、eled with the following information: supplier, date of manufacture, part number, part name, plant and location, and shipping date. Procedure 1. Clean the jars, lids (using laboratory washing machines) and seals (hand or machine wash) before each use. They must be clean and odorless. 2. A blank test
17、jar may be employed, as a control, to ensure that the jars are odorless and the water quality does not create an odor. 3. The jars containing the specimen(s) (or blank) should be conditioned and assessed per Table 2 below. TABLE 2: Summary of Test Conditions Use a separate specimen and jar for each
18、condition. Condition Temperature Test Time 1 23 2 C 24 h 1 h 2 40 2 C 24 h 1 h 3 65 2 C 2 h 10 min 4 (China Only)* 80 2 C 2 h 10 min *Applies to parts that are for the China market and regionally sourced only. Condition 1: Add 50 5 ml of distilled or deionized water to the jar(s). Take a stainless s
19、teel wire ring or support and suspend or stand the specimen(s) to be tested in the jar(s). The specimens are to be placed in the jar(s) in such a way to prevent direct contact with the water and to avoid wetting the specimen(s). Close the jar(s) and allow the specimen(s) to condition for 24 h 1 hr a
20、t 23 2 C. Immediately evaluate the odor. Condition 2: Pre-heat an oven to 40 2 C. Add 50 5 ml of distilled or deionized water to the jar(s). Take a stainless steel wire ring or support and suspend or stand the specimen(s) to be tested in the jar(s). The specimen(s) are to be placed in the jar(s) in
21、such a way to prevent direct contact with the water and to avoid wetting the specimen(s). FORD LABORATORY TEST METHOD BO 131-03 Copyright 2014, Ford Global Technologies, LLC Page 4 of 7 Close the jar(s) and place in the pre-heated oven for 24 h 1 hr at 40 2 C. Remove jar(s) from the pre-heated oven
22、and immediately evaluate the odor. Return the jar(s) to the pre-heated oven at 40 2 C for 15 2 minutes between odor assessments. Condition 3: Pre-heat oven to 65 2 C. Take a stainless steel wire ring or support and suspend or stand the specimen(s) to be tested in the jar(s). Close the jar(s) and pla
23、ce in the pre-heated oven for 2 h 10 min at 65 2 C. Remove the jar(s) from the pre-heated oven and immediately evaluate the odor. Three assessors (maximum) are permitted to evaluate the odor at one time. One minute, maximum total time, is allowed for the three assessors to evaluate the odor prior to
24、 returning the jars to the pre-heated 65 2 C oven*. Return the jar(s) to the pre-heated oven at 65 2 C for 15 mintues (minimum) between odor assessments. Condition 4 for CHINA ONLY: Pre-heat oven to 80 2 C. Take a stainless steel wire ring or support and suspend or stand the specimen(s) to be tested
25、 in the jar(s). Close the jar(s) and place in the pre-heated oven for 2 h 10 min at 80 2 C. Remove the jar(s) from the 80 2 C pre-heated oven then transfer the jar(s) to a second pre-heated oven at 65 2 C for 15 minutes (minimum). Remove the jar(s) from the 65 2 C pre-heated oven and immediately eva
26、luate the odor. Three assessors (maximum) are permitted to evaluate the odor at one time. One minute, maximum total, is allowed for the three assessors to evaluate the odor prior to returning the jars to the pre-heated 80 2 C oven*. Between odor assessments return the jars to the 80 2 C pre-heated o
27、ven for 30 5minutes. Then place the jar(s) in the 65 2 C pre-heated oven for 15 minutes (minimum) prior to the evaluation. * No more than three assessors are allowed per group. 4. Evaluating the Odor: The assessors should be selected from staff who do not work in the production facility. Heavy smoke
28、rs, users of strong perfumes, or people with sinus problems are not suitable. All assessors must be aware of any risk assessment documents and Toxicology reports of all submitted components, which should be readily available, if requested. Acceptance tests shall be made by a minimum of five assessor
29、s. If the rating of individual tests differs by more than two points, three additional assessors shall be used to retest the sample. The test must be conducted in an environment free from drafts and contaminant odors. FORD LABORATORY TEST METHOD BO 131-03 Copyright 2014, Ford Global Technologies, LL
30、C Page 5 of 7 The lid should be removed and the assessors nose should be positioned about 5 cm over the edge of the jar. The air from the jar should be wafted towards the assessors nose. The assessor should slowly inhale through the nose. The lid should not be off the jar longer than 5 seconds. Reco
31、rd the appropriate rating (refer to “Rating Scale“). If the assessor gives a rating which would be classed as a failure, a description of the odor must be included in the report. The person conducting the Odor Test should not allow the assessors to view any previous ratings or comments in any way. 5
32、. Repeat Step 4 for each assessor and each sample. 6. The odor rating is indicated by the arithmetic mean of all the assessors individual ratings, the value being rounded up to the nearest half point. To ensure that odor differentiation can be established by the assessors, all conditions being teste
33、d shall be conducted in the same time frame. For all the variants and conditions, the odor evaluation uses the rating of 1 to 6, with half-point ratings, as follows: Rating Scale Rating 1 not perceptible Rating 1.5 slightly perceptible Rating 2 perceptible, not disturbing Rating 2.5 clearly percepti
34、ble but not disturbing Rating 3 very perceptible but not disturbing Rating 3.5 intense enough to be slightly disturbing Rating 4 disturbing Rating 4.5 intense and disturbing Rating 5 strongly disturbing Rating 5.5 very intense, disturbing Rating 6 extremely disturbing The definition of a disturbing
35、odor is one that would be considered inappropriate for a new car smell. The smell of a component/ material is defined as disturbing, not when it is more concentrated, but rather when it transitions from one acceptable odor to another unacceptable odor upon conditioning. The concentrated odor of hot
36、plastic, hot rubber, hot leather, etc. would not qualify as a disturbing odor. A disturbing odor or inappropriate smell is also one that is identifiable as smells that are not normally associated with the interior of a new car, (i.e. sour milk, fish, perfume, burnt, musky, asphalt, rotten meat). The
37、 assessors should be encouraged to use the half point ratings to improve differentiation between samples. 7. The test report shall include: A reference to this standard. All necessary details for identifying the test samples. Material variant classification (A, B, C or D) from Table 1. Test conditio
38、n(s) (1, 2, 3, and/or 4) from Table 2. Identification of assessor by name or number. Individual and average odor rating. Samples defined as unacceptable should include an odor description.
